Waveform Graph and cursors position

[Jaiminho]

Dear:
I analyze an FFT graph that has different cursors. By code, do that cursors are multiples of a value in a numeric control (x1, x2, x3, x4, ...) through the property "Cursor Position: Cursor X". The problem that I find is that when looking at "Cursor Legend" some cursor position on the chart (time axis) is not correct when the time scale (x-axis) is great, except for some matching cursors position.
But when I decrease the scale of the time axis, all cursors tend to position themselves in the correct location.
Someone can tell me how I can solve this problem?
I need to take cursors correct position, independent of the size of the time scale.

Thanked since already
Best Regards

Jaime

When the range on an axis is large, cursor positions are inherently estimations since the cursor obviously can't fall between two screen pixels.
