Hi
I've added some lines with
ax.add_line(yellowlines)
ax.add_line(redlines)
how can I remove the lines without completely redrawing everything?

Hi Everyone,
I'm embedding two different figures on two different canvases (each
with subplots) into a Tk application, using the TkAgg backend. I'd
like to add some matplotlib widgets to one of the figures, and I need
to specify which figure to add these to. Currently, matplotlib is
putting the widgets on the figure that was the last to be created,
which is by default the active canvas, but I need to be able to
specify which widgets go where in my code, so I need to switch the
active figure. Normally during an interactive session, I would do
something like this:
figure(0)
# draw some lines
figure(1)
# draw some more
#now to add the widgets to figure 0, I need to make this active
figure(0)
# and now I can add my widgets
a = axis([0.0, 0.0, 0.1, 0.1]) # --> these are now drawn on figure 0
# etc...
But this won't work for embedded plots in a larger Tk program. So, my
question is, how can I select which canvas is active when I'm
embedding these figures using FigureCanvasTkAgg? I assumed there
would be a simple function like 'set_active' but I haven't found it.
I'm sure it's something simple that I'm missing.
Thanks very much,
Michael

Thanks Greg, that is exactly what I wanted.
Cheers

plot(data,zeros_like(data),marker='|',markersize=20,linestyle='None')

Hi all,
I needed to make bean plots (see
http://www.jstatsoft.org/v28/c01/paper ) so I made a function to plot
them by tuning the violin plot code from here:
http://pyinsci.blogspot.com/2009/09/violin-plot-with-matplotlib.html
Please see the attached file if interested.
Is there a repository where this kind of additional plot functions
could be submitted? The violinplot function needs scipy, so it's maybe
matplotlib itself is out of the question?
Best,
Teemu

I hope someone on this list can help me here. I am a complete matplotlib 
and python novice, so please forgive me if it is a rather simple question.
I am trying to plot markers in matplotlib. I have values at x at which 
they should appear, but that is it. The y value of them should just be 
an arbitrary value (for example 0).
Here is an example of the data
2.10686
4.21443
5.01784
6.20608
6.32343
6.44145
6.77794
...
..
.
I can load the data with
reflections_1=numpy.loadtxt("list.txt")
phase_1=reflections_1[:,0]
What is the best way of now plotting this (as single vertical marker lines)?
I thought of using the quiver function, but cannot get this to work.
Any help appreciated.
Thanks
Adrian
