Hi Gerrit, Thanks for the report, though I'm not sure what you expect to happen here? Changing at least one of the elements of x to be something other than nan does not cause the error. There is an inconsistency, though, in that plt.plot(x,x) when x is full of nans does not cause any errors. best, -- Paul Ivanov 314 address only used for lists, off-list direct email at: http://pirsquared.org | GPG/PGP key id: 0x0F3E28F7
