matplotlib-users Mailing List for matplotlib

I wish to produce a plot very much like that in  the examples -  
ganged_plots.py.
In these type of plots the tick labels on the end points of the y -  
axis tend to run into each other if nothing is done.
In the example -ganged_plots.py, this issue is addressed by judicious  
use of ylim and defining the ytick values explicitly.
In the example on the wiki, all  the ytick -labels are just made  
invisible.

I have not been able to figure out how to just make the first and  
last ytick labels vanish. I can make all the labels invisible, but I  
am unable to manipulate individual tick labels.
I thought that the following might work but this just makes all the  
labels disappear - my understanding is incomplete.
    ytl = a.get_yticklabels()
    ytl[0]._visible = False
    ytl[-1]._text = False

I vaguely recall that this was discussed before on the list - but I  
cannot locate the reference - if it exists.


Thanks for any help.

Darren, thanks a lot for your help!

I tried the animation_blit_tk example but it did not work as I expected it
to. It still was not possible to resize or maximize the window while the
animation was running.

However you gave me the clue to make it work by modifying the example just a
little.

I have been looking for a while to a solution to this problem, so let me
explain how I got it to work just in case someone is interested.

Basically, the original example (animation_blit_tk.py) does:

    manager = p.get_current_fig_manager()

followed by

    manager.window.after(1000, run)

to schedule the execution of a function (called run) 100 ms after the
function pylab.show() function is called. The problem is that their run
function has an infinite loop that does the animation and never exits. I
guess that does not let the GUI thread respond to GUI events (maximize and
resize).

Instead, the solution is to make the run function update the plot only once
(i.e. do one single animation frame) AND then call manager.window.after(100,
run) and return. This schedules the next animation frame but gives a chance
to the GUI thread to responds to events.

The single question that I have is whether this .window.after function works
with all types of GUI toolkits. I personally use Tk, since it comes builtin,
but does it also work with Wx and QT?

Thanks a lot for your help, Darren!

I dont think this is possible. usetex is kind of an all or nothing deal.
