SP5: first point of SignalConst is wrong renderer #4083
Description
Issue:
Will fixing LegendText bug in SignalConst I saw that rendering of first point is wrong.
I also noticed that Markers are not rendered!
ScottPlot Version: ScottPlot 5.0.36
Code Sample:
ScottPlot.Plot myPlot = new();
var sign = myPlot.Add.SignalConst(Generate.Sin(count:15, oscillations: 0.5));
sign.LegendText = "My fabulous Const LegendText";
sign.MarkerShape = MarkerShape.FilledCircle;
sign.MarkerSize = 20;
var sign2 = myPlot.Add.Signal(Generate.Sin(count: 15, oscillations: 0.5));
sign2.LegendText = "My fabulous LegendText";
sign2.MarkerSize = 20;
myShowLegend(Alignment.LowerCenter);
myPlot.SavePng("bug_signConst.png", 800, 600);
