We have analyzed the reported query. We would like to inform you that we have prepared the workaround for your requirement and this can be achieved by applying below code snippet.
Code Snippet [C#]:

public override void CreateSegments()
for (int i = 0; i < this.DataCount; i++)

double y2 = CloseValues[i];
if (y1 < y2)
this.Segments[i].Stroke = this.BullFillColor;
this.Segments[i].Stroke = this.BearFillColor;
