matplotlib-users Mailing List for matplotlib (Page 2)

There are lots of code examples on that page. You have yet to provide a
sscce. Nor have you posted what happens when you run your sscce. At the
very leat, post the traceback or the bad image that differs from what you
expect.

Thank you,
                  Ifact I was referring to the example given on the page. 
 http://earthpy.org/earthpy-basemap-amazon.html
Becasue it has reference to the data to be downloaed, I thought it is better to send the link rather than sending the code which need data.

With best regards,

Dear Developers/users,
                 I updated matplot lib to 1.4.2 and below example appears to be not working for m.scatter. May I know what change is implimented ?. m.scatter plots the river discharge in gridded format if the x,y=meshgrid(lon,lat) is used else it do not plot over map.

Thanks. That helps me in my understanding. Choosing bins = 6 fixes the
problem I reported.

Best,
Amit.

The best I can guess is that this is a bad binary build. Is SUSE repository
tracking the development branch of matplotlib or the stable release? What
version of matplotlib does zypper say it installed?

For the record, another way to handle this situation is to use subplot 
parameters to leave adequate room on the right, then use the 
Axes.add_axes() method to make an Axes for the colorbar, and provide it 
as a cax kwarg.

Hi Ben,

Thanks for those tips.  I ended up giving a list of axes to the ax argument
of colorbar as you suggested.  That took care of the misalignment of the
top plots and bottom plots but then the colorbar extended the full vertical
height of both rows of axes.  Fiddling with the shrink and anchor parameter
values then got me what I wanted.  I'm sure that axis_grid1 could work as
well, but my situation is sufficiently complicated that I don't want to
spend the time fiddling with it at this point.

Regards,
Jon

If you have matplotlib v1.3 (maybe 1.2, I can't remember), you can pass a
list of axes to the "ax" argument of colorbar, and it should steal space
equally from all the specified axes.

I am also particularly fond of using the mpl_toolkit axis_grid1, which
provides you a nice way to preallocate space for colorbars in different
ways:

I hope that helps!

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 one colorbar since the two images are forced to have the same
scaling.  Can anyone tell me how to insert the colorbar on the top right
without it taking space from the top right image -- or force the space to
be taken from the horizontal space of all the plots so the shapes are
uniform?  I've tried several approaches including using make_axes_locatable
from mpl_toolkits.axes_grid1 with no success.  I must admit that I don't
really understand what make_axes_locatable does, so it may be entirely the
wrong thing to use.  On the other hand, not using it, i.e. just using
plt.colorbar or fig.colorbar seems to do essentially the same thing, steal
space from the axes.  The basics of the plot are like this:

x = np.arange(20.)
xc = (x[:-1] + x[1:])/2.
y = np.arange(15.)
xx,yy = np.meshgrid(x,y)
z1 = np.random.randn(14,19)
z2 = np.random.randn(14,19)

fig,ax = plt.subplots(2,2)
pc = ax[0,0].pcolormesh(x,y,z1)
ax[1,0].plot(xc,z1[0,:])
ax[0,1].pcolormesh(x,y,z2)
ax[1,1].plot(xc,z2[0,:])
cb = plt.colorbar(pc, ax=ax[0,1])
plt.show()

Any help would be appreciated.

Regards,
Jon

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.  i.e. we don’t have “averspe” and “eels” so its hard for us to see what you are seeing.

glue does a lot of fancy interactive stuff, they might have something like
that.

It is looking more and more like that is what I will be doing over the

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 Matplotlib is not the end-all-be-all of plotting in
Python. There are a bunch of other tools that build off of matplotlib to
add more features and functionality. A bunch off the top of my head are:
bokeh, seaborn, mpldatacursor. There are a few others, but their names
aren't coming to me right now.

You need to do the azal.locator_params() call *after* you create azal. You
would get errors otherwise.

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 from a figure into another.

I guess this heavily depends of the backend used, or of the OS. So my
question is probably naive, but anyway :
is there a plan to add an interactive way to select one or more curves from
a matplotlib figure and to copy/paste them into a another figure ?

It is, I think, a killing feature for many beginners/average users who used
to work with matlab (oups, I've said it).

Best regards,

Julien

Doing

azal.locator_params(nbins=4)
azal = rif.add_subplot(111)
azal.plot(eels*(10**9), averspe, label='data')
azal.plot(eels*(10**9), beck, label='fit')

the program runs but locator_params doesn't do anything

doing:

azal.yaxis.locator_params(nbins=4)
azal = rif.add_subplot(111)
azal.plot(eels*(10**9), averspe, label='data')
azal.plot(eels*(10**9), beck, label='fit')

it continue to say that yaxis has not this attribute.

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

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.

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.

is the easy way.  You can also write your own “Locators” that are more sophisticated if you have some ideas in mind (i.e. close to 5 ticks, but you’d prefer whole numbers, etc).

Hi Ben,

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

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.
http://matplotlib.org/api/widgets_api.html#matplotlib.widgets.RectangleSelector

I can imagine that you could set up a selector callback that could then
query the data on the graph to "snap" the final line to the nearest points
on the graph, creating a Line2D object on the fly. Is that what you are
looking for?

Cheers!
Ben Root

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

Gabriele
