- optional legend with toggle buttons to quickly show/hide items
- default styling based on current ImGui theme, but most elements can be customized independently
- customizable data getters and data striding (just like ImGui:PlotLine)
- relatively good performance for high density plots
- support for single and double precision data
- accepts data as float, double, and 8, 16, 32, and 64-bit signed/unsigned integral types
- and more! (see [Announcements](https://github.com/epezent/implot/issues/48))

## Integration
0) Set up an [ImGui](https://github.com/ocornut/imgui) environment if you don't already have one.
1) Add `implot.h`, `implot_internal.h`, `implot.cpp`, `implot_items.cpp` and optionally `implot_demo.cpp` to your sources. Alternatively, you can get ImPlot using [vcpkg](https://github.com/microsoft/vcpkg/tree/master/ports/implot).
2) Create and destroy an `ImPlotContext` wherever you do so for your `ImGuiContext`:

Of course, this assumes you already have an ImGui-ready environment. If not, consider trying [mahi-gui](https://github.com/mahilab/mahi-gui), which bundles ImGui, ImPlot, and several other packages for you.
You should be good to go!

## Special Notes
- If you experience data truncation and/or visual glitches, it is **HIGHLY** recommended that you EITHER:
1) Handle the `ImGuiBackendFlags_RendererHasVtxOffset` flag in your renderer when using 16-bit indices (the official OpenGL3 renderer supports this) and use an ImGui version with patch [imgui@f6120f8](https://github.com/ocornut/imgui/commit/f6120f8e16eefcdb37b63974e6915a3dd35414be), OR...
2) Enable 32-bit indices by uncommenting `#define ImDrawIdx unsigned int` in your `imconfig.h` file.
- By default, no anti-aliasing is done on line plots for performance reasons. If you use 4x MSAA, then you likely won't even notice. However, you can enable software AA per-plot with the `ImPlotFlags_AntiAliased` flag, or globally with `ImPlot::GetStyle().AntiAliasedLines = true;`.

**Q: Is ImPlot the right plotting library for me?**
A: If you're looking to generate publication quality plots and/or export plots to a file, ImPlot is NOT the library for you. ImPlot is geared toward plotting application data at realtime speeds with as little user code as possible. ImPlot does its best to create pretty plots (indeed there are quite a few styling options available), but it will always favor function over form.

A: Not currently. Use your OS's screen capturing mechanisms if you need to capture a plot. ImPlot is not suitable for rendering publication quality plots; it is only intended to be used as a visualization tool. Post-process your data with MATLAB or matplotlib for these purposes.
**Q: Does ImPlot handle double precision data?**
**Q: What date types can I plot?**
A: Yes, ImPlot accepts both `float` and `double` for all of its plotting functions.
A: ImPlot plotting functions accept most scalar types:
`float`, `double`, `int8`, `uint8`, `int16`, `uint16`, `int32`, `uint32`, `int64`, `uint64`.
**Q: Can ImPlot be used with other languages/bindings?**
A: Yes, you can use the C binding, [cimplot](https://github.com/cimgui/cimplot) with most high level languages. [DearPyGui](https://github.com/hoffstadt/DearPyGui) provides a Python wrapper, among other things. A Rust binding, [implot-rs](https://github.com/4bb4/implot-rs), is currently in the works. An example using Emscripten can be found [here](https://github.com/pthom/implot_demo).
