Hi all,
how can I create line segments between consecutive selected points of a
scatter plot in an interactive manner ? It should be possible to create
several unclosed polygonal lines. Each polygonal line might have
a different color.
A small example is appreciated.
Thanks in advance.

Hi all,
I'm trying to set the NUMBER of ticks on a subplot axis.
Googling I'm finding only how to set the ticks values...but what if I don't
know them and for visual reasons I would like to have a fixed number of
ticks?
thanks

Nils,
Perhaps the rectangle selector might be of use? It defaults to a draw mode
of 'box', but you can set it to line so that it looks like a ruler widget.

I can imagine that you could set up a selector callback that

I have attached a sample scatter plot. The task is to add lines to the

Hi,
I already saw that stack overflow page but
this is my code:
azal = rif.add_subplot(111)
azal.plot(eels*(10**9), averspe, label='data')
azal.plot(eels*(10**9), beck, label='fit')
I tried to add both
azal.yaxis.locator_params(nbins=4)
or
azal.locator_params(nbins=4)
and it doesn't work.
I wonder if setting the locator params prior to plotting would fix that?
Might be one of those rare situations where the order of commands matter in
matplotlib.

I would just call use `plot` and keep track of the Line2D objects returned.

Dear all,
We're, at our lab, trying to (slowly) make the transition from a famous
(but expansive) numerical software to Python.
The most recurring remark made against the use of Python/Matplotlib instead
of this famous software is the fact that one cannot male simple
click/copy/paste of a curve
You need to do the azal.locator_params() call *after* you create azal. You
would get errors otherwise.

Plans? No. This is the first I have ever heard of such a feature. You could
always add a feature request for it (this is a community-developed tool).
It might even fold in nicely with the MEP22 work going on to refactor our
interactivity and make it easier to add tools.
Keep in mind that
glue does a lot of fancy interactive stuff, they might have something like
that.
From a reproducible computing PoV that functionality is a bit of a problem
until we have a way to serialize figures.
It is looking more and more like that is what I will be doing over the
holidays

Yes, this works fine:
import numpy as np
import matplotlib.pyplot as plt
eels= np.random.rand(12)
averspe = np.random.rand(12)
fig,azal = plt.subplots(1,1)
azal.locator_params(nbins=10)
azal.plot(eels, averspe, label='data')
Cheers, Jody
PS, easiest is to include self-contained examples.
Hi,
I'm trying to make a plot with four panes (2x2). The two on top are
images, created with pcolormesh, while the ones on the bottom are line
plots. I'd like to the axes to line up -- which they do -- but when I add
a colorbar to the top right, it steals space from the image plot. I only
need
