[Matplotlib-users] plotting durations

I don't think there is a built-in way to do this, but I thought I'd check first. Can matplotlib (somehow) directly plot a duration of time, such as in the form: 0:01:39.983001 (h:m:s:microsec) Thanks, Che -- This SF.net

[Matplotlib-users] Change Hue-Range in HSV color map

Hi, I would like to change the hue range of the hsv color map to use only hue values between 0 and 0.6667. I checked the documentation of matplotlib and searched in the internet but couldn't find the answer. Best regards, KB -- View this message in context: http://www.nabble.com/Change-Hue-Ran

It just occurred to me that another option might be to simply add a new colour option "line" for mec and mfc which would instruct them to pick up the current line colour. Gary -- This SF.net email is sponsored by: Sourc

Hi Norbert, Both of your proposals (b) and (c) sound better to me than the current behaviour, although they don't sound as obvious to me as simply defaulting to always setting the mec to the line colour unless overridden using mec="k" - you could label this proposal (d). Since others seem to h

I figured out why your show() works...you had WxPython installed and I'm assuming your backend was defaulting to this since Tkinter wasn't found. Once I noticed that I installed WxPython and then re-buily matplotlib with WxPython. If I used wxpython as my backend, then my GUIs worked. I can impo
