Path lacks initial MOVETO

Community matplotlib-users

Hello everyone,

I have been using matplotlib 0.99.3 to write some down. But I had to upgrade my OS and so installed the last version of the library 1.1.0. But unfortunately when I try to run my code I get the following error:

raise ValueError, ‘Path lacks initial MOVETO’

ValueError: Path lacks initial MOVETO

I have been goggling it and saw some reports about it when using a vector containing zeros for which I apply a log and then trying to plot this. But the reports seem to indicate this was fixed in a svn version I can’t access anymore.

Can anyone point me on the correct direction to solve this problem?

Thank you very much in advance,

Bruno Santos

Could you provide a bit more information: Are you calling Path directly? If not, do you know what in your code is calling it? A minimal, runnable example would be very helpful.

Cheers,

Sorry it took me a while to get back to you. I have finally written some code to replicate the problem. I have attached a file with it.

Thank you very much in advance,
