[SOLVED] Is there a way to determine a axis by position

[suilenroc1183]

Hi,
I have a chart with several y - axis and I will program a feature that a configuration dialog opens on double click on a axis.

My problem is to determine the axis under the mouse pointer. Is there a way to calculate the drawing area of an axis?

Thanks in advance

I do have plans to implement axis tools, but have no time right now.

Meanwhile, you can use TChartAxis.IsPointInside function.

Hi,
thanks for this tip. IsPointInside is good enough for me to solve my problem.

Thanks for your great work on TAChart.

To make things clearer, it could be mentioned that TChartAxis.IsPointInside behaves as TChartAxis.Marks.IsPointInside
If I click on the axis title, TChartAxis.IsPointInside returns false, still the title is a part of the axis.

Example:

Code: [Select]

procedure TForm1.FormCreate(Sender: TObject);
begin
  Chart1.LeftAxis.Title.Visible:=True;
  Chart1.LeftAxis.Title.Caption:='Left axis title';
end;

procedure TForm1.Chart1MouseDown(Sender: TObject; Button: TMouseButton;
  Shift: TShiftState; X, Y: Integer);
var
  APoint: TPoint;
begin
  APoint.x:=X;
  APoint.y:=Y;
if Chart1.LeftAxis.IsPointInside(APoint)= True then ShowMessage ('Inside');
end;
I would like to use the case to ask if there is a way to determine where the axis title is in the chart and/or if the mouse is inside it?
