The list below represents a combination of high-priority work, nice-to-have features, and random ideas. We make no guarantees that all of this work will be completed or even started. If you see something that you need or would like to have, let us know, or better yet consider submitting a PR for the feature.
API
Axes
- add flag to remove weekends on Time axis
- pixel space scale (
ImPlotTransform_Display
), normalized space scale (ImPlotTransform_Axes
), data space scale (ImPlotTransform_Data
) - make ImPlotFlags_Equal not a flag ->
SetupEqual(ImPlotAxis x, ImPlotAxis y)
- allow inverted arguments
SetAxes
to transpose data? SetupAxisColors()
SetupAxisHome()
Plot Items
- add
PlotBubbles
(see MATLAB bubble chart) - add non-zero references for
PlotBars
etc. - add exploding to
PlotPieChart
(on hover-highlight?) - fix appearance of
PlotBars
spacing
Styling
- support gradient and/or colormap sampled fills (e.g. ImPlotFillStyle_)
- API for setting different fonts for plot elements
Colormaps
- gradient editing tool
RemoveColormap
enum ImPlotColorRule_ { Solid, Faded, XValue, YValue, ZValue }
Legend
ImPlotLegendFlags_Scroll
- improve legend icons (e.g. adopt markers, gradients, etc)
- make legend frame use ButtonBehavior (maybe impossible)
Tools / Misc.
- add
IsPlotChanging
to detect change in limits - add ability to extend plot/axis context menus
- add LTTB downsampling for lines
- add box selection to axes
- first frame render delay might fix "fit pop" effect
- move some code to new
implot_tools.cpp
- ColormapSlider (see metrics)
- FillAlpha should not affect markers?
- fix mouse text for time axes
Optimizations
- find faster way to buffer data into ImDrawList (very slow)
- reduce number of calls to
PushClipRect
- explore SIMD operations for high density plot items
Plotter Pipeline
Ideally every PlotX
function should use our faster rendering pipeline when it is applicable.

Completed
- make BeginPlot take fewer args:
- make query a tool ->
DragRect
- rework DragLine/Point to use ButtonBehavior
- add support for multiple x-axes and don't limit count to 3
- make axis side configurable (top/left, right/bottom) via new flag
ImPlotAxisFlags_Opposite
- add support for setting tick label strings via callback
- give each axis an ID, remove ad-hoc DND solution
- allow axis to be drag to opposite side (ala ImGui Table headers)
- legend items can be hovered even if plot is not
- fix frame delay on DragX tools
- remove tag from drag line/point -> add
Tag
tool - add shortcut/legacy overloads for BeginPlot
SetupAxisConstraints()
SetupAxisScale()
- add
ImPlotLineFlags
,ImPlotBarsFlags
, etc. for each plot type - add
PlotBarGroups
wrapper that makes rendering groups of bars easier, with stacked bar support PlotBars
restore outlines- add hover/active color for plot axes
