Grid with Top Axis

Grid lines use the bottom and left axes by default, but this behavior can be customized for plots which use other axes.

GridRecipes.cs

ScottPlot.Plot myPlot = new();

var sig = myPlot.Add.Signal(ScottPlot.Generate.Sin());
sig.Axes.XAxis = myPlot.Axes.Top;
myPlot.Grid.XAxis = myPlot.Axes.Top;

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