How do i get the coordinates from more then 1 mark ?
This code don't get the coordinates !
For id=0 to antalrows-1
Set mark = c.xAxis2().addMark(DataSerie3nr(id), &H900066FF, DataSerie3txt(id), "arialbd.ttf")
EventMark(IdMark) = mark.getImageCoor()
IdMark = IdMark+1
End If
Next
I want to show some info where special events occurred.
I can only get coordinates after the "c.makeSession" code, and then it is only the last coordinate.
Please help
Thanks

Hi Thomas,
As you have already known, the coordinates can only be obtained after the chart is drawn. Before the chart is drawn, the coordinates are not fixed (you can keep adding more data, and the axis scale will change to reflect your data), so you cannot get the coordinates.
Would you mind to clarify how you get the coordinates after makeSession? It should be similar to your current code, except that you store the mark instead of the mark coordinates:
Set mark = c.xAxis2().addMark(DataSerie3nr(id), &H900066FF, DataSerie3txt(id), "arialbd.ttf")
Set EventMark(IdMark) = mark
IdMark = IdMark + 1
Then after makeSession, you can use a for loop to get the coordinates as EventMark(IdMark).getImageCoor().
Hope this can help.

Hi Peter
Thank you.
It was the method for getting coordinates for more than one mark i needed.
Your example clarified that.
Set EventMark(IdMark) = mark
EventMark(IdMark).getImageCoor()
