Re: [Matplotlib-users] Formatter dates
Thanks for the reply! Do you know what makes X climb? And can you control its on some way? // Tim From: jdh2...@gmail.com Date: Wed, 17 Nov 2010 05:55:04 -0600 Subject: Re: [Matplotlib-users] Formatter dates To: qw...@hotmail.com CC: matplotlib-users@lists.sourceforge.net On Wed, Nov 17, 2010 at 2:29 AM, Tim Åberg qw...@hotmail.com wrote: Hello!

Re: [Matplotlib-users] Formatter dates
Thanks for the reply! I have been looking into it now and thinks i have get the hang of how it works rougly. Do you know any way to know the max-value of X straight away? I have a list of dates that with listlength Y, the X spans from 0 - something. So if i could figure out what something is i could get the ratio and then plot the dates by indexing the ratio times X eg. (Xmax / listlength) * X. // Tim From: jdh2...@gmail.com Date: Wed, 17 Nov 2010 05:55:04 -0600 Subject: Re: [Matplotlib-users] Formatter dates To: qw...@hotmail.com CC: matplotlib-users@lists.sourceforge.net On Wed, Nov 17, 2010 at 2:29 AM, Tim Åberg qw...@hotmail.com wrote: Hello!

Re: [Matplotlib-users] Formatter dates
I just checked it up, and it had some nice function, the timeseries looked nice and maybe i can use it in some way (time_series looked interesting) . I dont want to go away from Linecollection way of plotting due to its speed or is the timeseries-way a fast way of plotting?
