SignalConst: Update GetAxisLimits() to include data offsets #4485
Description
Issue: Some days ago, we have successfully exposed Data property of SignalConst (#4440). Now XOffset can be set from the outside but it's still not taken into account.
ScottPlot Version: ScottPlot.WPF, 5.0.44
Code Sample:
var ys = [1, 2, 3, 4, 5]
var period = 1;
var offsetX = 100;
// With Signal, the offset works fine
var signalPlot = plot.Plot.Add.Signal(ys, period)
signalPlot.Data.XOffset = offsetX;
// For SignalConst, offsetX has no effect
var signalConstPlot = plot.Plot.Add.SignalConst(ys, period)
signalConstPlot.Data.XOffset = offsetX;
