Re: CPI_POSITION returns unexpected values - Bug?

[Software FX]

No. This is not a bug. This coordinates are relative to the chart window, so 

when drawing in the screen the chart it is only offset by the border (+1) so 

that when you get the Device Context (CPI_GETDC) you draw relative to that 

position. This behavior is the same in Chart FX 3.0 and 98. 

The CPI_POSITION call is particularly useful when you print the chart since 

the chart is not drawn at 0,0 or close. 

You want your pixel position to be relative to what ? to the whole chart 

window ? maybe you want to use Windows API's ClientToScreen and 

ScreenToClient functions.
