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.
- 2026/02/12 (1.0) - ImPlotSpec replaces the SetNextXXX style functions. The guide below shows show to migrate from SetNextXXX to ImPlotSpec.
- `SetNextLineStyle` has been removed, styling should be set via ImPlotSpec.
```
// Before
ImPlot::SetNextLineStyle(line_color, line_weight);
ImPlot::PlotLine("Line", xs, ys, count);
// After
ImPlotSpec spec;
spec.LineColor = line_color;
spec.LineWeight = line_weight;
ImPlot::PlotLine("Line", xs, ys, count, spec);
```
- `SetNextFillStyle` has been removed, styling should be set via ImPlotSpec.
```
// Before
ImPlot::SetNextFillStyle(fill_color, fill_alpha);
ImPlot::PlotLine("Shaded", xs, ys, count, ImPlotLineFlags_Shaded);
// After
ImPlotSpec spec;
spec.FillColor = fill_color;
spec.FillAlpha = fill_alpha;
spec.Flags = ImPlotLineFlags_Shaded;
ImPlot::PlotTLine("Shaded", xs, ys, count, spec);
```
- SetNextMarkerStyle has been removed, styling should be set via ImPlotSpec.
```
// Before
ImPlot::SetNextMarkerStyle(marker, marker_size, fill_color, line_weight, marker_outline_color);
ImPlot::PlotScatter("Scatter", xs, ys, count);
// After
ImPlotSpec spec;
spec.LineWeight = line_weight;
spec.Marker = marker;
spec.MarkerSize = marker_size;
spec.MarkerLineColor = marker_outline_color;
spec.MarkerFillColor = fill_color;
ImPlot::PlotScatter("Scatter", xs, ys, count, spec);
```
- SetNextErrorBarStyle has been removed, styling should be set via ImPlotSpec.
```
// Before
ImPlot::SetNextErrorBarStyle(color, size, weight);
ImPlot::PlotErrorBars("ErrorBar", xs, ys, err, count);
// After
ImPlotSpec spec;
spec.LineColor = color;
spec.Size = size;
spec.LineWeight = weight;
ImPlot::PlotErrorBars("ErrorBar", xs, ys, err, count, spec);
```
- Flags, Offset and Stride should also be set via ImPlotSpec now.
- 2023/10/02 (1.0) - ImPlotSpec was made the default and _only_ way of styling plot items. Therefore the following features were removed:
- ImPlotCol_Line, ImPlotCol_Fill, ImPlotCol_MarkerOutline, ImPlotCol_MarkerFill, ImPlotCol_ErrorBar have been removed and thus are no longer supported by PushStyleColor.
You can use a common ImPlotSpec instance across multiple PlotX calls to emulate PushStyleColor behavior.
- ImPlotStyleVar_LineWeight, ImPlotStyleVar_Marker, ImPlotStyleVar_MarkerSize, ImPlotStyleVar_MarkerWeight, ImPlotStyleVar_FillAlpha, ImPlotStyleVar_ErrorBarSize, and ImPlotStyleVar_ErrorBarWeight
have been removed and thus are no longer supported by PushStyleVar. You can use a common ImPlotSpec instance across multiple PlotX calls to emulate PushStyleVar behavior.
- ImPlotStyle/ImPlotStyleVar_ DigitalBitGap was renamed to DigitalSpacing; DigitalBitHeight was removed (use ImPlotSpec::Size); DigitalPadding was added for padding from bottom.
- PlotX offset, stride, and flags parameters are now incorporated into ImPlotSpec; specify these variables in the ImPlotSpec passed to PlotX.
- 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 unnecessary 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.
