Figure Background Image

An image can be used for the background of a figure.

This code sample is specific to ScottPlot 5 (details)
ScottPlot.Plot myPlot = new();

// plot sample data
var sig1 = myPlot.Add.Signal(Generate.Sin());
var sig2 = myPlot.Add.Signal(Generate.Cos());

// One could load an image from a file...
// Image bgImage = new("background.png");

// But in this example we will use a sample image:
Image bgImage = SampleImages.MonaLisa();
myPlot.FigureBackground.Image = bgImage;

// Color the axes and data so they stand out against the dark background
sig1.Color = sig1.Color.Lighten(.2);
sig2.Color = sig2.Color.Lighten(.2);
sig1.LineWidth = 3;
sig2.LineWidth = 3;

// Shade the data area to make it stand out
myPlot.DataBackground.Color = Colors.Black.WithAlpha(.5);

myPlot.SavePng("demo.png", 400, 300);
