For more advanced uses, you may want to read from: - - io.NavActive: true when a window is focused and it doesn't have the ImGuiWindowFlags_NoNavInputs flag set. - - io.NavVisible: true when the navigation cursor is visible (and usually goes false when mouse is used). - - or query focus information with e.g. IsWindowFocused(ImGuiFocusedFlags_AnyWindow), IsItemFocused() etc. functions. - Please reach out if you think the game vs navigation input sharing could be improved. - - Gamepad: - - Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad to enable. - - Backend: Set io.BackendFlags |= ImGuiBackendFlags_HasGamepad + fill the io.NavInputs[] fields before calling NewFrame(). - Note that io.NavInputs[] is cleared by EndFrame(). - - See 'enum ImGuiNavInput_' in imgui.h for a description of inputs. For each entry of io.NavInputs[], set the following values: - 0.0f= not held. 1.0f= fully held. Pass intermediate 0.0f..1.0f values for analog triggers/sticks. - - We uses a simple >0.0f test for activation testing, and won't attempt to test for a dead-zone. - Your code will probably need to transform your raw inputs (such as e.g. remapping your 0.2..0.9 raw input range to 0.0..1.0 imgui range, etc.). - - You can download PNG/PSD files depicting the gamepad controls for common controllers at: http://goo.gl/9LgVZW. - - If you need to share inputs between your game and the imgui parts, the easiest approach is to go all-or-nothing, with a buttons combo - to toggle the target. Please reach out if you think the game vs navigation input sharing could be improved. - - Mouse: - - PS4 users: Consider emulating a mouse cursor with DualShock4 touch pad or a spare analog stick as a mouse-emulation fallback. - - Consoles/Tablet/Phone users: Consider using a Synergy 1.x server (on your PC) + uSynergy.c (on your console/tablet/phone app) to share your PC mouse/keyboard. - - On a TV/console system where readability may be lower or mouse inputs may be awkward, you may want to set the ImGuiConfigFlags_NavEnableSetMousePos flag. - Enabling ImGuiConfigFlags_NavEnableSetMousePos + ImGuiBackendFlags_HasSetMousePos instructs dear imgui to move your mouse cursor along with navigation movements. - When enabled, the NewFrame() function may alter 'io.MousePos' and set 'io.WantSetMousePos' to notify you that it wants the mouse cursor to be moved. - When that happens your back-end NEEDS to move the OS or underlying mouse cursor on the next frame. Some of the binding in examples/ do that. - (If you set the NavEnableSetMousePos flag but don't honor 'io.WantSetMousePos' properly, imgui will misbehave as it will see your mouse as moving back and forth!) - (In a setup when you may not have easy control over the mouse cursor, e.g. uSynergy.c doesn't expose moving remote mouse cursor, you may want - to set a boolean to ignore your other external mouse positions until the external source is moved again.) - - API BREAKING CHANGES ==================== Occasionally introducing changes that are breaking the API.

For varieties of reason this is more self-explanatory. + - 2020/09/21 (1.79) - removed return value from OpenPopupOnItemClick() - returned true on mouse release on an item - because it is inconsistent with other popup APIs and makes others misleading. It's also and unnecessary: you can use IsWindowAppearing() after BeginPopup() for a similar result. + - 2020/09/17 (1.79) - removed ImFont::DisplayOffset in favor of ImFontConfig::GlyphOffset. DisplayOffset was applied after scaling and not very meaningful/useful outside of being needed by the default ProggyClean font.

Otherwise, you may skip submitting the contents of a cell/column, BUT ONLY if you know +// it is not going to contribute to row height. +// In many situations, you may skip submitting contents for every column but one (e.g. the first one). +// - Case A: column is not hidden by user, and at least partially in sight (most common case). +// - Case B: column is clipped / out of sight (because of scrolling or parent ClipRect): TableNextColumn() return false as a hint but we still allow layout output. +// - Case C: column is hidden explicitly by the user (e.g. via the context menu, or _DefaultHide column flag, etc.). +// +// [A] [B] [C] +// TableNextColumn(): true false false -> [userland] when TableNextColumn() / TableSetColumnIndex() returns false, user can skip submitting items but only if the column doesn't contribute to row height. +// SkipItems: false false true -> [internal] when SkipItems is true, most widgets will early out if submitted, resulting is no layout output. +// ClipRect: normal zero-width zero-width -> [internal] when ClipRect is zero, ItemAdd() will return false and most widgets will early out mid-way. +// ImDrawList output: normal dummy dummy -> [internal] when using the dummy channel, ImDrawList submissions (if any) will be wasted (because cliprect is zero-width anyway). +// +// - We need to distinguish those cases because non-hidden columns that are clipped outside of scrolling bounds should still contribute their height to the row. +// However, in the majority of cases, the contribution to row height is the same for all columns, or the tallest cells are known by the programmer. +//----------------------------------------------------------------------------- +// About clipping/culling of whole Tables: +// - Scrolling tables with a known outer size can be clipped earlier as BeginTable() will return false. +//----------------------------------------------------------------------------- + +//----------------------------------------------------------------------------- +// [SECTION] Header mess +//----------------------------------------------------------------------------- + +#if defined(_MSC_VER) && !defined(_CRT_SECURE_NO_WARNINGS) +#define _CRT_SECURE_NO_WARNINGS +#endif + +#ifndef IMGUI_DEFINE_MATH_OPERATORS +#define IMGUI_DEFINE_MATH_OPERATORS +#endif + +#include "imgui.h" +#ifndef IMGUI_DISABLE +#include "imgui_internal.h" + +// System includes +#include // intptr_t + +// Visual Studio warnings +#ifdef _MSC_VER +#pragma warning (disable: 4127) // condition expression is constant +#pragma warning (disable: 4996) // 'This function or variable may be unsafe': strcpy, strdup, sprintf, vsnprintf, sscanf, fopen +#if defined(_MSC_VER) && _MSC_VER >= 1922 // MSVC 2019 16.2 or later +#pragma warning (disable: 5054) // operator '|': deprecated between enumerations of different types +#endif +#pragma warning (disable: 26451) // [Static Analyzer] Arithmetic overflow : Using operator 'xxx' on a 4 byte value and then casting the result to a 8 byte value.

We try to make the breakage minor and easy to fix. -Below is a change-log of API breaking changes only. If you are using one of the functions listed, expect to have to fix some code. -When you are not sure about a old symbol or function name, try using the Search/Find function of your IDE to look for comments or references in all implot files. -You can read releases logs https://github.com/epezent/implot/releases for more details. - -- 2020/09/07 (0.8) - Plotting functions which accept a custom getter function pointer have been post-fixed with a G (e.g. PlotLineG) -- 2020/09/06 (0.7) - Several flags under ImPlotFlags and ImPlotAxisFlags were inverted (e.g. ImPlotFlags_Legend -> ImPlotFlags_NoLegend) so that the default flagset - is simply 0. This more closely matches ImGui's style and makes it easier to enable non-default but commonly used flags (e.g. ImPlotAxisFlags_Time). -- 2020/08/28 (0.5) - ImPlotMarker_ can no longer be combined with bitwise OR, |. This features caused unecessary slow-down, and almost no one used it. -- 2020/08/25 (0.5) - ImPlotAxisFlags_Scientific was removed. Logarithmic axes automatically uses scientific notation. -- 2020/08/17 (0.5) - PlotText was changed so that text is centered horizontally and vertically about the desired point. -- 2020/08/16 (0.5) - An ImPlotContext must be explicitly created and destroyed now with `CreateContext` and `DestroyContext`. Previously, the context was statically initialized in this source file. -- 2020/06/13 (0.4) - The flags `ImPlotAxisFlag_Adaptive` and `ImPlotFlags_Cull` were removed. Both are now done internally by default. -- 2020/06/03 (0.3) - The signature and behavior of PlotPieChart was changed so that data with sum less than 1 can optionally be normalized. The label format can now be specified as well. -- 2020/06/01 (0.3) - SetPalette was changed to `SetColormap` for consistency with other plotting libraries. `RestorePalette` was removed. Use `SetColormap(ImPlotColormap_Default)`. -- 2020/05/31 (0.3) - Plot functions taking custom ImVec2* getters were removed. Use the ImPlotPoint* getter versions instead. -- 2020/05/29 (0.3) - The signature of ImPlotLimits::Contains was changed to take two doubles instead of ImVec2 -- 2020/05/16 (0.2) - All plotting functions were reverted to being prefixed with "Plot" to maintain a consistent VerbNoun style. `Plot` was split into `PlotLine` - and `PlotScatter` (however, `PlotLine` can still be used to plot scatter points as `Plot` did before.). `Bar` is not `PlotBars`, to indicate - that multiple bars will be plotted. -- 2020/05/13 (0.2) - `ImMarker` was change to `ImPlotMarker` and `ImAxisFlags` was changed to `ImPlotAxisFlags`. -- 2020/05/11 (0.2) - `ImPlotFlags_Selection` was changed to `ImPlotFlags_BoxSelect` -- 2020/05/11 (0.2) - The namespace ImGui:: was replaced with ImPlot::. As a result, the following additional changes were made: - - Functions that were prefixed or decorated with the word "Plot" have been truncated. E.g., `ImGui::PlotBars` is now just `ImPlot::Bar`. - It should be fairly obvious what was what. - - Some functions have been given names that would have otherwise collided with the ImGui namespace. This has been done to maintain a consistent - style with ImGui. E.g., 'ImGui::PushPlotStyleVar` is now 'ImPlot::PushStyleVar'. -- 2020/05/10 (0.2) - The following function/struct names were changes: - - ImPlotRange -> ImPlotLimits - - GetPlotRange() -> GetPlotLimits() - - SetNextPlotRange -> SetNextPlotLimits - - SetNextPlotRangeX -> SetNextPlotLimitsX - - SetNextPlotRangeY -> SetNextPlotLimitsY -- 2020/05/10 (0.2) - Plot queries are pixel based by default. Query rects that maintain relative plot position have been removed. This was done to support multi-y-axis. - -*/ - -#include "implot.h" -#include "implot_internal.h" - -#ifdef _MSC_VER -#define sprintf sprintf_s -#endif - -// Global plot context -ImPlotContext* GImPlot = NULL;

We try to make the breakage minor and easy to fix. +Below is a change-log of API breaking changes only. If you are using one of the functions listed, expect to have to fix some code. +When you are not sure about a old symbol or function name, try using the Search/Find function of your IDE to look for comments or references in all implot files. +You can read releases logs https://github.com/epezent/implot/releases for more details. + +- 2023/08/20 (0.17) - ImPlotFlags_NoChild was removed as child windows are no longer needed to capture scroll. You can safely remove this flag if you were using it. +- 2023/06/26 (0.15) - Various build fixes related to updates in Dear ImGui internals. +- 2022/11/25 (0.15) - Make PlotText honor ImPlotItemFlags_NoFit. +- 2022/06/19 (0.14) - The signature of ColormapScale has changed to accommodate a new ImPlotColormapScaleFlags parameter +- 2022/06/17 (0.14) - **IMPORTANT** All PlotX functions now take an ImPlotX_Flags `flags` parameter. Where applicable, it is located before the existing `offset` and `stride` parameters. + If you were providing offset and stride values, you will need to update your function call to include a `flags` value. If you fail to do this, you will likely see + unexpected results or crashes without a compiler warning since these three are all default args. We apologize for the inconvenience, but this was a necessary evil. + - PlotBarsH has been removed; use PlotBars + ImPlotBarsFlags_Horizontal instead + - PlotErrorBarsH has been removed; use PlotErrorBars + ImPlotErrorBarsFlags_Horizontal + - PlotHistogram/PlotHistogram2D signatures changed; `cumulative`, `density`, and `outliers` options now specified via ImPlotHistogramFlags + - PlotPieChart signature changed; `normalize` option now specified via ImPlotPieChartFlags + - PlotText signature changes; `vertical` option now specified via `ImPlotTextFlags_Vertical` + - `PlotVLines` and `PlotHLines` replaced with `PlotInfLines` (+ ImPlotInfLinesFlags_Horizontal ) + - arguments of ImPlotGetter have been reversed to be consistent with other API callbacks + - SetupAxisScale + ImPlotScale have replaced ImPlotAxisFlags_LogScale and ImPlotAxisFlags_Time flags + - ImPlotFormatters should now return an int indicating the size written + - the signature of ImPlotGetter has been reversed so that void* user_data is the last argument and consistent with other callbacks +- 2021/10/19 (0.13) - MAJOR API OVERHAUL! See #168 and #272 + - TRIVIAL RENAME: + - ImPlotLimits -> ImPlotRect + - ImPlotYAxis_ -> ImAxis_ + - SetPlotYAxis -> SetAxis + - BeginDragDropTarget -> BeginDragDropTargetPlot + - BeginDragDropSource -> BeginDragDropSourcePlot + - ImPlotFlags_NoMousePos -> ImPlotFlags_NoMouseText + - SetNextPlotLimits -> SetNextAxesLimits + - SetMouseTextLocation -> SetupMouseText + - SIGNATURE MODIFIED: + - PixelsToPlot/PlotToPixels -> added optional X-Axis arg + - GetPlotMousePos -> added optional X-Axis arg + - GetPlotLimits -> added optional X-Axis arg + - GetPlotSelection -> added optional X-Axis arg + - DragLineX/Y/DragPoint -> now takes int id; removed labels (render with Annotation/Tag instead) + - REPLACED: + - IsPlotXAxisHovered/IsPlotXYAxisHovered -> IsAxisHovered(ImAxis) + - BeginDragDropTargetX/BeginDragDropTargetY -> BeginDragDropTargetAxis(ImAxis) + - BeginDragDropSourceX/BeginDragDropSourceY -> BeginDragDropSourceAxis(ImAxis) + - ImPlotCol_XAxis, ImPlotCol_YAxis1, etc. -> ImPlotCol_AxisText (push/pop this around SetupAxis to style individual axes) + - ImPlotCol_XAxisGrid, ImPlotCol_Y1AxisGrid -> ImPlotCol_AxisGrid (push/pop this around SetupAxis to style individual axes) + - SetNextPlotLimitsX/Y -> SetNextAxisLimits(ImAxis) + - LinkNextPlotLimits -> SetNextAxisLinks(ImAxis) + - FitNextPlotAxes -> SetNextAxisToFit(ImAxis)/SetNextAxesToFit + - SetLegendLocation -> SetupLegend + - ImPlotFlags_NoHighlight -> ImPlotLegendFlags_NoHighlight + - ImPlotOrientation -> ImPlotLegendFlags_Horizontal + - Annotate -> Annotation + - REMOVED: + - GetPlotQuery, SetPlotQuery, IsPlotQueried -> use DragRect + - SetNextPlotTicksX, SetNextPlotTicksY -> use SetupAxisTicks + - SetNextPlotFormatX, SetNextPlotFormatY -> use SetupAxisFormat + - AnnotateClamped -> use Annotation(bool clamp = true) + - OBSOLETED: + - BeginPlot (original signature) -> use simplified signature + Setup API +- 2021/07/30 (0.12) - The offset argument of `PlotXG` functions was been removed. Implement offsetting in your getter callback instead. +- 2021/03/08 (0.9) - SetColormap and PushColormap(ImVec4*) were removed. Use AddColormap for custom colormap support. LerpColormap was changed to SampleColormap. + ShowColormapScale was changed to ColormapScale and requires additional arguments. +- 2021/03/07 (0.9) - The signature of ShowColormapScale was modified to accept a ImVec2 size. +- 2021/02/28 (0.9) - BeginLegendDragDropSource was changed to BeginDragDropSourceItem with a number of other drag and drop improvements. +- 2021/01/18 (0.9) - The default behavior for opening context menus was change from double right-click to single right-click. ImPlotInputMap and related functions were moved + to implot_internal.h due to its immaturity. +- 2020/10/16 (0.8) - ImPlotStyleVar_InfoPadding was changed to ImPlotStyleVar_MousePosPadding +- 2020/09/10 (0.8) - The single array versions of PlotLine, PlotScatter, PlotStems, and PlotShaded were given additional arguments for x-scale and x0. +- 2020/09/07 (0.8) - Plotting functions which accept a custom getter function pointer have been post-fixed with a G (e.g. PlotLineG) +- 2020/09/06 (0.7) - Several flags under ImPlotFlags and ImPlotAxisFlags were inverted (e.g. ImPlotFlags_Legend -> ImPlotFlags_NoLegend) so that the default flagset + is simply 0. This more closely matches ImGui's style and makes it easier to enable non-default but commonly used flags (e.g. ImPlotAxisFlags_Time). +- 2020/08/28 (0.5) - ImPlotMarker_ can no longer be combined with bitwise OR, |. This features caused unecessary slow-down, and almost no one used it. +- 2020/08/25 (0.5) - ImPlotAxisFlags_Scientific was removed. Logarithmic axes automatically uses scientific notation. +- 2020/08/17 (0.5) - PlotText was changed so that text is centered horizontally and vertically about the desired point. +- 2020/08/16 (0.5) - An ImPlotContext must be explicitly created and destroyed now with `CreateContext` and `DestroyContext`. Previously, the context was statically initialized in this source file. +- 2020/06/13 (0.4) - The flags `ImPlotAxisFlag_Adaptive` and `ImPlotFlags_Cull` were removed. Both are now done internally by default. +- 2020/06/03 (0.3) - The signature and behavior of PlotPieChart was changed so that data with sum less than 1 can optionally be normalized. The label format can now be specified as well. +- 2020/06/01 (0.3) - SetPalette was changed to `SetColormap` for consistency with other plotting libraries. `RestorePalette` was removed. Use `SetColormap(ImPlotColormap_Default)`. +- 2020/05/31 (0.3) - Plot functions taking custom ImVec2* getters were removed. Use the ImPlotPoint* getter versions instead. +- 2020/05/29 (0.3) - The signature of ImPlotLimits::Contains was changed to take two doubles instead of ImVec2 +- 2020/05/16 (0.2) - All plotting functions were reverted to being prefixed with "Plot" to maintain a consistent VerbNoun style. `Plot` was split into `PlotLine` + and `PlotScatter` (however, `PlotLine` can still be used to plot scatter points as `Plot` did before.). `Bar` is not `PlotBars`, to indicate + that multiple bars will be plotted. +- 2020/05/13 (0.2) - `ImMarker` was change to `ImPlotMarker` and `ImAxisFlags` was changed to `ImPlotAxisFlags`. +- 2020/05/11 (0.2) - `ImPlotFlags_Selection` was changed to `ImPlotFlags_BoxSelect` +- 2020/05/11 (0.2) - The namespace ImGui:: was replaced with ImPlot::. As a result, the following additional changes were made: + - Functions that were prefixed or decorated with the word "Plot" have been truncated. E.g., `ImGui::PlotBars` is now just `ImPlot::Bar`. + It should be fairly obvious what was what. + - Some functions have been given names that would have otherwise collided with the ImGui namespace. This has been done to maintain a consistent + style with ImGui. E.g., 'ImGui::PushPlotStyleVar` is now 'ImPlot::PushStyleVar'. +- 2020/05/10 (0.2) - The following function/struct names were changes: + - ImPlotRange -> ImPlotLimits + - GetPlotRange() -> GetPlotLimits() + - SetNextPlotRange -> SetNextPlotLimits + - SetNextPlotRangeX -> SetNextPlotLimitsX + - SetNextPlotRangeY -> SetNextPlotLimitsY +- 2020/05/10 (0.2) - Plot queries are pixel based by default. Query rects that maintain relative plot position have been removed. This was done to support multi-y-axis. + +*/ + +#define IMGUI_DEFINE_MATH_OPERATORS +#include "implot.h" +#include "implot_internal.h" + +#include + +// Support for pre-1.82 versions.

The behavior of this color depends upon the style color to +// which it as applied: +// +// 1) For style colors associated with plot items (e.g. ImPlotCol_Line), +// IMPLOT_AUTO_COL tells ImPlot to color the item with the next unused +// color in the current colormap. Thus, every item will have a different +// color up to the number of colors in the colormap, at which point the +// colormap will roll over. For most use cases, you should not need to +// set these style colors to anything but IMPLOT_COL_AUTO; you are +// probably better off changing the current colormap. However, if you +// need to explicitly color a particular item you may either Push/Pop +// the style color around the item in question, or use the SetNextXXXStyle +// API below. If you permanently set one of these style colors to a specific +// color, or forget to call Pop, then all subsequent items will be styled +// with the color you set. +// +// 2) For style colors associated with plot styling (e.g. ImPlotCol_PlotBg), +// IMPLOT_AUTO_COL tells ImPlot to set that color from color data in your +// **ImGuiStyle**. The ImGuiCol_ that these style colors default to are +// detailed above, and in general have been mapped to produce plots visually +// consistent with your current ImGui style. Of course, you are free to +// manually set these colors to whatever you like, and further can Push/Pop +// them around individual plots for plot-specific styling (e.g. coloring axes). + +// Provides access to plot style structure for permanant modifications to colors, sizes, etc. +IMPLOT_API ImPlotStyle& GetStyle(); + +// Style plot colors for current ImGui style (default). +IMPLOT_API void StyleColorsAuto(ImPlotStyle* dst = nullptr); +// Style plot colors for ImGui "Classic". +IMPLOT_API void StyleColorsClassic(ImPlotStyle* dst = nullptr); +// Style plot colors for ImGui "Dark". +IMPLOT_API void StyleColorsDark(ImPlotStyle* dst = nullptr); +// Style plot colors for ImGui "Light". +IMPLOT_API void StyleColorsLight(ImPlotStyle* dst = nullptr); + +// Use PushStyleX to temporarily modify your ImPlotStyle.
