ImPlot.jl

Plotting extension library that can be used in conjunction with CImGui.jl to provide enhanced immediate-mode data visualization.

ImPlot.jl provides an interface to cimplot, which is an auto-generated C API to implot, a C++ plotting extension library for imgui.

Installation

Simple installation via the package registry:

]add ImPlot

Example Usage

Use demo/implot_demo.jl to check if things are working via:

include("implot_demo.jl")
show_demo()

implot_demo.jl replicates all the plotting functionality visible in implot_demo.cpp of implot v0.8, with the exception of examples using Tables (depends on upstream imgui) and custom plotting with implot_internal.h functions (depends on cimplot v0.9).

Aside from the replication of the C++ interface, we have some convenience for some things that are slightly less verbose. See demo/example_plots.jl and below.

## within a CImGui.jl render loop
## This assumes you have CImGui.LibCImGui.ImGuiCond_Once in scope
...

if show_window
    @c CImGui.Begin("Plot Window", &show_window)
    y = rand(1000)
    ImPlot.SetNextPlotLimits(0.0,1000,0.0,1.0, ImGuiCond_Once)
    if (ImPlot.BeginPlot("Foo", "x1", "y1", CImGui.ImVec2(-1,300)))
        ImPlot.PlotLine(y)
        ImPlot.EndPlot()
    end
    CImGui.End()
end
