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.
