[TCursorTool] Invisible when superimposed

Hello,
I'm using 2 CursorTool on my chart. My problem is that sometimes the 2 cursors must be at the same position. But if the 2 cursors are superimposed, they are not visible anymore. Is there a way to avoid this problem ?

Hi bertrod,
I'm afraid this is a bug, I've added it (TV52011928) to our defect list to be fixed for future releases.
In the meantime, you can try changing tool's pen width when they overlap, for example:
Code: Select all
procedure TForm1.ChartTool1Change(Sender: TCursorTool; x, y: Integer;
const XValue, YValue: Double; Series: TChartSeries; ValueIndex: Integer);
begin
if ChartTool1.XValue=ChartTool2.XValue then
ChartTool1.Pen.Width:=2
else
ChartTool1.Pen.Width:=1
end;
procedure TForm1.ChartTool2Change(Sender: TCursorTool; x, y: Integer;
const XValue, YValue: Double; Series: TChartSeries; ValueIndex: Integer);
begin
if ChartTool1.XValue=ChartTool2.XValue then
ChartTool2.Pen.Width:=2
else
ChartTool2.Pen.Width:=1
end;
