SignalXY: Too many markers drawn in step display mode #1896
Description
After version > 4.1.33 if StepDisplay = true every point to draw a line to is now marked with a marker (if marker size > 0).
Possible fix in SignalPlotXYGeneric.cs:
add line
PointF[] PointsToMark = (PointF[])PointsToDraw.Clone();
before
if (StepDisplay)
PointsToDraw = GetStepPoints(PointsToDraw);
and replace variable PointsToDraw with PointsToMark in the section below where the drawing of the markers is done
if (PointsToMark.Length > 1)
{
float dataSpanXPx = PointsToMark[PointsToMark.Length - 1].X - PointsToMark[0].X;
float markerPxRadius = .3f * dataSpanXPx / PointsToMark.Length;
markerPxRadius = Math.Min(markerPxRadius, MarkerSize / 2);
float scaledMarkerSize = markerPxRadius * 2;
if (markerPxRadius > .3)
{
// skip not visible before and after points
var PointsWithMarkers = PointsToMark
.Skip(PointBefore.Length)
.Take(PointsToDraw.Length - PointBefore.Length - PointAfter.Length)
.ToArray();
MarkerTools.DrawMarkers(gfx, PointsWithMarkers, MarkerShape, scaledMarkerSize, MarkerColor, MarkerLineWidth);
}
}
