You can read releases logs https://github.com/epezent/implot/releases for more details.
- 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).
