Two annotations for cursor tool

Currently cursor tool has only one annotation on the bottom axis. Is it possible to have two annotations one on the bottom axis and the second on the left axis?

Hi Vladimir,
You can add as many TAnnotationTools as you want and calculate their position at the TColorLineTool OnDragLine event.

Hi Yeray
I know, I can add, but as cursor tool has one X-annotation tool, for symmetry can be the second Y-annotation.

Hi Vladimir,
Sorry, I misread it and understood you were talking about the TAnnotationTool in the TColorLineTool, while you clearly mentioned it's about the TAnnotationTool on the
TCursorTool.
I've added it to the public tracker:

Hi Yeray
As I can this issue is not fixed yet.
Would you like to tell, how this can be fixed?

Hi Vladimir,
Note this is a feature request to be implemented, more than a bug to be fixed.
I'm afraid you are right, this hasn't been implemented yet, but since the same result can already be done without much effort with the current set of tools, I wouldn't give this a much elevated priority.

Exactly. I did it like this:
Code: Select all
procedure TForm8.cursorToolChange(
Sender: TCursorTool;
x, y: Integer;
const XValue, YValue: Double;
Series: TChartSeries;
ValueIndex: Integer);
begin
annotationTool.Top := Y - (annotationTool.Height div 2);
annotationTool.Text := YValue.ToString();
end;
