Hello MeteoBB<br>
<br>
I've struggled with the same problem. I tend to forget sometimes
that contouring is not magic. Plotting your data under the contours
shows that there are considerable areas of your plot where there are
no data. The spatial pattern and sparsity of your points are
challenging to contour. Perhaps contouring is not the best method to
illustrate these data. Are you asking the routine to do something
that it is not designed to do? Just plotting the points coloured by
magnitude may give a better representation of the actual data. You
can also scale the size of each coloured point by it's magnitude.
This can be quite an effective representation of this type of data.<br>
