[Matplotlib-users] Bar graph color
Hey guys, I'm a new guy in here and amazed by the capability Matplotlib has. I have a question for you, which might be a result of my ignorance or the limitation of the current Matplotlib. I'm trying to make a bar chart with hundreds of bars at different x positions with their own y values (so called mass spectra) and would like to have different colors for some of them, but the bar colors were never changed to what I intended. Then, I realized because each bar is so narrow I can't see the color of the bars but only outside lines (I see the colors by zooming it), which I couldn't find a way to change the color. My question is, is there any way either 1) to get rid of the outside lines or 2) to change the color of the lines? Thanks much in advance! Young Jin - This SF.net email is sponsored by: Splunk Inc.

For (1), use the linewidth=0 kwarg, e.g.: barh(pos,val, align='center', linewidth=0) Eric Young Jin - This SF.net email is sponsored by: Splunk Inc. Still grepping through log files to find problems?

My question is, is there any way either 1) to get rid of the outside lines or 2) to change the color of the lines? Thanks much in advance! To get rid of the lines, set the linewidth property of the bars to 0; to change their color, set the edgecolor property. For example, using ipython -pylab: In [31]: a=bar([1,2,3,4],[3,1,4,1],lw=0) In [32]: setp(a[1], lw=10, ec='red') Out[32]: [None, None] Here I used the abbreviations lw and ec for linewidth and edgecolor. The first command creates a bar chart where all bars have line width zero, the second modifies one of the bars to have very thick red edges. You can experiment with the properties using the pylab commands getp and setp. -- Jouni K. Seppänen http://www.iki.fi/jks - This SF.net email is sponsored by: Splunk Inc.

Re: [Matplotlib-users] stuck after a mpl_connect - how to disconnect and go on
Hi thanks a lot for this feedback! Your example is quite nice indeed. However there is something I may not have fully understand. If I use the example you sketch, I of course need to call the displayer class (right?), by doing something like: test = displayer() However, then I hit the same problem again: I would need to define ALL the commands I wish to go through WITHIN the displayer class (and more precisely into the show_next function), because any command put after the test = displayer() would be executed anyway without waiting that I finally hit the right mouse button. Or is there something I didn't catch which would allow me to go around this? (what my program is supposed to do at the end is to go through a series of (3xdataframes), and for each dataframe in turn, use the offset trick, then reinitialise everything and start with the next series... This seems to imply that I need to specify the full set of commands within the displayer class show_next function) thanks again Eric - This SF.net email is sponsored by: Splunk Inc.

[Matplotlib-users] Looking for a way to save a graph
Hello, I would like to save a matplotlib figure (data, title and axes label, plot properties, ...) to load it later on for modification. Something like figure.savelall(file.matplot) and later on do a figure.loadall(file.matplot) using an empty figure. Did somebody already implement such a functionality? If yes Is it available somewhere or are you eager to share it? Thanks, David - This SF.net email is sponsored by: Splunk Inc. Still grepping through log files to find problems? Stop.

Reasonable request, reasonable solution, but alas neither will work. The mpl extension code doesn't support pickling. JDH - This SF.net email is sponsored by: Splunk Inc.

Pickling only works for objects that have been designed for it. Such design is not trivial for extension code, and has not been done for mpl. Eric - This SF.net email is sponsored by: Splunk Inc.

I'm not sure why this is a problem. Yes, you need to put all your code into the callback routines of displayer, but just think of it as wrapping your program code inside the class. Your __main__ code then simply becomes test = displayer()... and away you go. Also, I realised shortly after sending my email that you can of course do away with the offset class in this example, and put those methods into the displayer class too, which will make things a little simpler. Or is there something I didn't catch which would allow me to go around this? (what my program is supposed to do at the end is to go through a series of (3xdataframes), and for each dataframe in turn, use the offset trick, then reinitialise everything and start with the next series... This seems to imply that I need to specify the full set of commands within the displayer class show_next function) thanks again Eric Angus. -- AJC McMorland, PhD Student Physiology, University of Auckland - This SF.net email is sponsored by: Splunk Inc.
