I have test data measured on X, Y circular grid and and reported as X,Y, data in a file with three coloumns.

X, Y and data are not sorted in any particular fashion.

I need to plot the data on X, Y defining the circular grid.

I do not seem to be gerttring any where.

Any assistance would be very helpul.

Are you wanting the graph to be like a polar plot (with circular grid lines) instead of a cartesian plot?

This is the plot I get with scatter() and this is what I more or less expect, except that the data values are not colored by magnitude which would have been nicer.

However, as mentioned above, my end goal is to get a profile at 45 degree angle (cross-section of the above plot to a line passing through the origin). I have created a seperate thread for this problem.
