Hi akim, Have you tried to pass your data to ChartDirector to plot the contour chart? If there is an issue, would you mind to clarify what is the issue? Regards Peter Kwan

Hi akim,

First, modify your data, so that the x range is from -180 to 180 (not from 180 to 360 then from 0 - 180). The code is:

For i = 0 To Ubound(dataX)
If dataX(i) > 180 Then dataX(i) = dataX(i) - 360
Next

Then your x-axis will be from -180 to 180. To label your axis, you may use:

Call c.setLinearScale(-180, 180, Array("", 210, 240, 270, 300, 330, 0, 30, 60, 90, 120, 150, 180))

So even internally, the dataX is -180 to 180, the labels will show ("", 210, 240, 270, 300, 330, 0, 30, 60, 90, 120, 150, 180).

Hope this can help.

Regards
Peter Kwan
