I'm having trouble getting your C code to compile (maybe a gsl version mismatch...?)
In the meantime, perhaps you could try something for me. If you add the kwarg "solid_joinstyle='bevel'" or "solid_joinstyle='round'" to your plot command, does that improve things? If so, we could consider changing the default. Cheers, Mike mtcoder wrote: > All, > > Thanks for the quick and informative responses. I've attached the code > (testode.c).
