The plotting module provides a bunch of plotting widgets to imgui. We use the implot library to handle this functionality.

To enable the plotting module, update your uvproj.yaml so that the plotting key under enabled-modules is set to true like this:

name: "MyProject"
version: "1.0.0.0"
engine-version: "1.0.0.0"
enabled-modules:
  plotting: true

Then, regenerate the modules cache by running the following command:

user $ ./UVKBuildTool --generate <project directory>

After that, refresh your CMake project with cmake ..!

Next, in your source file, include the Modules.hpp header in your components like this:

#include <Modules/Modules.hpp>

The entire module is flagged as event safe at All ready

In one of your widgets, add the following code to your tick function

ImGui::SetNextItemWidth(250);
if (ImPlot::BeginPlot("##Pie1", ImVec2(350, 350), ImPlotFlags_Equal | ImPlotFlags_NoMouseText))
{
    static const char* labels[] = { "Data 1", "Data 2" };
    double dt[] = { 10.0f, 12.0f };
    ImPlot::SetupAxis(ImAxis_X1, nullptr, ImPlotAxisFlags_NoDecorations);
    ImPlot::SetupAxis(ImAxis_Y1, nullptr, ImPlotAxisFlags_NoDecorations);
    ImPlot::SetupAxesLimits(0, 1, 0, 1, ImPlotCond_Always);
    ImPlot::SetupLegend(ImPlotLocation_North | ImPlotLocation_West, ImPlotLegendFlags_Horizontal);
    ImPlot::PlotPieChart(labels, dt, 2, 0.5, 0.5, 0.4, "%.3f", 90.0f, ImPlotPieChartFlags_Normalize);
    ImPlot::EndPlot();
}

and if you run your application, you will get some type of output like this:

To learn more about using implot, check out the implot GitHub repository.

To check for the module at compile time, use the UIMGUI_PLOTTING_MODULE_ENABLED macro.

Runtime checking can be done using the plotting member of the ModuleSettings struct. More info can be found here.

There is a C API for the plotting module as part of the cimgui_extra project.
