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

Enabling the module

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>

Event safety

The entire module is flagged as event safe at All ready.

Testing out the module

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:

Learning the module

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

Checking for the module

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.
