API BREAKING CHANGES
====================
Occasionally introducing changes that are breaking the API. 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.
- 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.
