Hi Christian,
Thanks, that works indeed! I should have tried a little bit harder, I
suppose.
Regarding this huge number of points, it is actually needed: my data
consists in thousands of lines of various amplitude, and I want to be able
to distinguish one of these lines from its neighbour as well as comprehend
the global variation in amplitude. However, you're right that it may be a
pain for the user, and I will consider using an image instead. Actually,
that was my workaround, but I was not satisfied with this.
So thanks for your help and comments.
Best regards,
Aurélien
