Re: [Matplotlib-users] Plot data with specified time (hour, minute, second)

Ok.
I tried to do the job through the old way and it's working.
But I have the latest version (0.91.2). Is it possible that my version
wasn't successfully installed and that an older one is doing the job ?
Anyway, thanks a lot for the (fast) help.
