If you want to test ImPlot quickly, consider trying [mahi-gui](https://github.com/mahilab/mahi-gui), which bundles ImGui, ImPlot, and several other packages for you.
## Installing ImPlot using vcpkg
You can download and install ImPlot using the [vcpkg](https://github.com/Microsoft/vcpkg) dependency manager:
```bash
git clone https://github.com/Microsoft/vcpkg.git
cd vcpkg
./bootstrap-vcpkg.sh
./vcpkg integrate install
./vcpkg install implot
```
The ImPlot port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please [create an issue or pull request](https://github.com/Microsoft/vcpkg) on the vcpkg repository.
## Extremely Important Note
Dear ImGui uses **16-bit indexing by default**, so high-density ImPlot widgets like `ImPlot::PlotHeatmap()` may produce too many vertices into `ImDrawList`, which causes an assertion failure and will result in data truncation and/or visual glitches. Therefore, it is **HIGHLY** recommended that you EITHER:

**Q: What data types can I plot?**
A: ImPlot plotting functions accept most scalar types:
`float`, `double`, `int8`, `uint8`, `int16`, `uint16`, `int32`, `uint32`, `int64`, `uint64`. Arrays of custom structs or classes (e.g. `Vector2f` or similar) are easily passed to ImPlot functions using the built-in striding features (see `implot.h` for documentation), and many plotters provide a "getter" overload which accepts data generating callbacks. Additional support for `long`, `unsigned long` and `long double` can be added by defining `IMPLOT_INSTANTIATE_ALL_NUMERIC_TYPES` at compile-time. Also, you can fully customize the list of accepted types: see doc in `implot_items.cpp`.

// You can customize the supported types in two ways:
// 1. Define IMPLOT_INSTANTIATE_ALL_NUMERIC_TYPES at compile time to add support for all known types.
// 2. Or, define IMPLOT_CUSTOM_NUMERIC_TYPES at compile time to define your own type list. As an example, you could use the compile time define given by the line below in order to support only float and double.
