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.
- 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.

// Supported Types for T*
// The template functions below are explicitly instantiated in implot_items.cpp.
// They are not intended to be used generically with custom types. You will get
// a linker error if you try! All functions support the following scalar types:
//
// float, double, ImS8, ImU8, ImS16, ImU16, ImS32, ImU32, ImS64, ImU64
//
//
// If you need to plot custom or non-homogenous data you have a few options:
//
// 1. If your data is a simple struct/class (e.g. Vector2f), you can use striding.
// This is the most performant option if applicable.
//
// struct Vector2f { float X, Y; };
// ...
// Vector2f data[42];
// ImPlot::PlotLine("line", &data[0].x, &data[0].y, 42, 0, sizeof(Vector2f)); // or sizeof(float)*2
//
// 2. Write a custom getter function or C++ lambda and pass it and your data to
// an ImPlot function post-fixed with a G (e.g. PlotScatterG). This has a
// slight performance cost, but probably not enough to worry about.
//
// ImPlotPoint MyDataGetter(void* data, int idx) {
// MyData* my_data = (MyData*)data;
// ImPlotPoint p;
// p.X = my_data->GetTime(idx);
// p.Y = my_data->GetValue(idx);
// return p
// }
// ...
// MyData my_data;
// ImPlot::PlotScatterG("scatter", MyDataGetter, &my_data, my_data.Size());

// if you try plotting extremely large 64-bit integral types. Proceed with caution!
