Extra features for ImPlot.jl:
image!— fast image/heatmap display. A large scalar matrix (colormapped) or an RGB(A) image is uploaded once as a GPU texture and drawn as a single quad, so it stays fast at resolutions whereImPlot'sPlotHeatmapslows down.colorbar!— a colorbar for arbitrary nonlinear colorscales (e.g. logarithmic), with correct tick locations and labels. It is interactive: scroll to zoom, drag to pan the displayed range.
See the docstrings for details and arguments, and examples/example.jl
for a runnable demo.
