[Matplotlib-users] Vertical bar - making the bar fixed width
How do I set my vertical bar to be fixed width? Depending on amount of data on my x axis, the bars get created accordingly and the width gets adjusted to fit into the graph. If I have only 2 plots on the x axis then the 2 bars get stretched across the entire graph. Looks very ugly. -Alen - This SF.net email is sponsored by: Splunk Inc.

I keep coming back to this from time-to-time and have a go a poking around in the mpl codebase but I've never figured out exactly what state the matplotlib "Lazy Values" and "BinOps" store. If this internal state could be retrieved and then later restored, then python can pickle the extension objects using the copy-reg module. It might be enough if methods were added to the BinOp objects to retrieve internal objects to which they link. You could then recursively walk through the whole lazy-value tree. To make this work, you would need to retrieve the underlying C++ objects with it's python wrapper object intact (i.e. with the same IDs) so that python references to that object created elsewhere still work. While the concept of Lazy Values is easy enough to understand, understanding how and where these objects fit in to the MPL architecture is hard. I think a little documentation or explanation of this could go a long way to helping implement this. If I could understand all the places the Lazy Values are used, I'm keen to attempt the implementation of pickle-ability. One problem for me is my C++ knowledge is ~ 0.

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.

Won't work. 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.

Reasonable request, reasonable solution, but alas neither will work.
The mpl extension code doesn't support pickling.

I am but a humble newbie, but why not simply take your figure
object/reference and Pickle it (see
http://docs.python.org/lib/module-pickle.html)?

[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

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.
