Hi,

Rather than adding a line from the drawing toolbar consider using another
data series to draw the line

Hi All,

I have a line graph with minutes on y axis but scaling may vary from small
values to large ones. I want to draw a level line at 15 minutes with
AddLine
method. I can do that manually, but how can I calculate the position of 15
minutes (in points as required by the AddLine method) on y axis if its
place
varies with scaling of y axis? (or is there any other way?)

Thanks,
Stefi
