Plot a CurveFit, Polynomial or set of points to a PNG file.

Generates a filename based on the source file, line number, and timestamp.

• Creates the necessary directories if they don’t exist.
• Prints the path of the generated file to stdout.
• If prefix is specified, it is prepended to the filename.

Examples

plot!(fit);
plot!([fit, poly1, poly2]);
plot!(fit, PlotOptions<_> { title: "My Plot", ..Default::default() });
plot!([fit, poly1], PlotOptions<_> { title: "My Plot", ..Default::default() }, prefix = "custom");
