matplotlib-users Mailing List for matplotlib

I tried this and although it sort-of works, it doesn't really do what I
need. I tried using this:

import matplotlib.pyplot as plt
import matplotlib.path as mpath
import numpy as np
import copy

# create figure and axes
fig = plt.figure(figsize=(6, 6))
ax = fig.add_axes([.1, .1, .8, .8])
ax.set_xlim([-3, 3])
ax.set_ylim([-3, 3])

# a circle at the origin with radius 1
circle = plt.Circle((0, 0), 1, transform=ax.transData,
                    edgecolor='k', facecolor='none')

# from Phil's example
exterior = mpath.Path.unit_rectangle()
interior = circle.get_path()
exterior = mpath.Path(copy.deepcopy(exterior.vertices),
                      copy.deepcopy(exterior.codes[:]))
interior.vertices = interior.vertices[::-1]
exterior.vertices *= 6
exterior.vertices -= 3
clip_path = mpath.Path(vertices=np.concatenate([exterior.vertices,
interior.vertices]),
                       codes=np.concatenate([exterior.codes,
interior.codes]))

# lines from the origin dividing the axes into 8 sectors
end_coords = [(3, 0), (3, 3), (0, 3), (-3, 3),
              (-3, 0), (-3, -3), (0, -3), (3, -3)]
for x, y in end_coords:
    line, = ax.plot((x, 0), (y, 0), color='k')
    line.set_clip_path(clip_path, ax.transData)

ax.add_artist(circle)

plt.show()

and the result is the attached image with_clipping.png. You should see that
the circle is no longer circular, and also there are weird line width
issues. What I want it basically exactly like the attached
without_clipping.png but with paths inside the circle removed.

Thanks

You would build and install basemap from the git source as you would
normally from a tarball source.  Make modifications to the source, do a
"python setup.py install", test, and repeat as needed.  When happy, commit
those changes to your local branch, push that branch up to your github
account, and then from github make a PR.

The instructions for basemap wouldn't be all that different from
matplotlib, which can be found here:
http://matplotlib.org/devel/gitwash/index.html

Cheers!

You could just use paths which have holes in them, making the exterior so
broad that you wouldn't notice the edge of the clipping. I've put together
an example of doing just that:

import matplotlib.pyplot as plt
import matplotlib.path as mpath
import matplotlib.collections as mcol
import numpy as np
import copy


exterior = mpath.Path.unit_rectangle()
exterior = mpath.Path(copy.deepcopy(exterior.vertices),
                      copy.deepcopy(exterior.codes[:]))
exterior.vertices *= 4
exterior.vertices -= 2
interior = mpath.Path.unit_circle()
interior.vertices = interior.vertices[::-1]
clip_path = mpath.Path(vertices=np.concatenate([exterior.vertices,
interior.vertices]),
                       codes=np.concatenate([exterior.codes,
interior.codes]))

star = mpath.Path.unit_regular_star(6)
star.vertices *= 2.6


ax = plt.subplot(321)
col = mcol.PathCollection([clip_path], facecolor='yellow')
ax.add_collection(col)
ax.set_title('Clip path')
ax.set_xlim([-3, 3])
ax.set_ylim([-3, 3])


ax = plt.subplot(322)
col = mcol.PathCollection([star], facecolor='red')
ax.add_collection(col)
ax.set_title('Target polygon')
ax.set_xlim([-3, 3])
ax.set_ylim([-3, 3])


ax = plt.subplot2grid((3, 2), (1, 0), colspan=2, rowspan=2)
col = mcol.PathCollection([star])
col.set_clip_path(clip_path, ax.transData)
ax.add_collection(col)

ax.set_title('Target polygon clipped by clip_path')
ax.set_xlim([-3, 3])
ax.set_ylim([-3, 3])

plt.tight_layout()

plt.show()

[image: Inline images 1]



There are other options if this doesn't cut the mustard.

Hi

I'd like to be able to clip a line so that the portion of it lying outside
of a given polygon remains visible and the part that lies inside of the
polygon is not visible. What I want is basically the opposite of:

    line.set_clip_path(polygon)

which leaves only the part of the line inside the polygon visible. Is this
possible?

I know I can just fill the polygon with the background color or something
but this gets messy when there are other lines on the plot that don't need
to be clipped.

Thanks,
Andrew

Dear all,

I've successfully forked matplotlib.basemap to 
ThomasLecocq.basemap and cloned ThomasLecocq.basemap to my machine. Now,
 how can I have this clone be THE mpl_toolkits.basemap package, so I can
 make edits in the __init__.py (that contains the Basemap class) and 
preview them "live" on this machine. Once they are nice and OK, I can 
commit/push it to my master on github and probably create a pull request
 to the matplotlib.basemap git ?

Thanks a lot in advance,

Thom

ps : if this mail goes through and the previous didn't, might be becaused I did not use the forked term in the subject...

Thank You Phil,
                                  It did it correctly. TkAgg is good with interactive plotting.

I hadn't spotted you were using the WxAgg backend too - this looks like the same bug that Brendan reported yesterday. 

The easiest solution would be to use another back-end until this is fixed. Do you have 'TkAgg' available? I currently do not have a wx installation to hand to try out any workarounds at the moment.

Hi,

Did some more testing with the 
"http://matplotlib.org/examples/user_interfaces/embedding_in_wx5.html" 
example and see the same problem/crash.

Attached the slightly adapted version of the script (using wxPython 2.9 
and wx.App instead of wx.SimpleApp which is deprecated in 2.9) and the 
setup.py script I used to generated the py2exe'd version.

The py2exe'd version works without problem on my Intel Core i5 but 
crashes on an AMD Athlon 2400+ equiped PC.

Anyone has some tips, ideas on how to track this down?

Best regards
Werner

Thank you Phil, 
                            But I had tried it earlier after seeing a another mail thread. I get command prompt but no figure pops up.

In [3]: import matplotlib.pyplot as plt

In [4]: plt.ion()

In [5]: plt.plot(range(10))
Out[5]: [<matplotlib.lines.Line2D at 0x410f250>]

In [6]: 

 Any way out??
with best regards,
Sudheer

Hi Sudheer,

Try the interactive mode (http://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.ion):


>>> import matplotlib.pyplot as plt
>>> plt.ion()
>>> plt.plot(range(10))
[<matplotlib.lines.Line2D object at 0x1c565d0>]

**a figure pops up here and hands you back the python command line**

I don't know of any reason why one shouldn't be able to use the wxAgg
backend interactively.
This looks like a bug to me. Would you mind adding this as an issue on the
github issue tracker?

Thanks,

Hi Mike,

Do you have any code or an image to show the problem?

Cheers,

Hi Sudheer,

Try the interactive mode (
http://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.ion):


>>> import matplotlib.pyplot as plt
>>> plt.ion()
>>> plt.plot(range(10))
[<matplotlib.lines.Line2D object at 0x1c565d0>]

**a figure pops up here and hands you back the python command line**

>>>

Regards,

Dear experts,
Is there a way to get back to the prompt after a plot is made and displayed with out closing the plot?
The objective is to compare to plots or check some aspect about the plot made from the loaded variables. This is the standard behavior of matlab after plotting we get the prompt and we can make another plot if we want to compare 2. I know there is subplot option but it will be of small size if I need to make a spatial map at to time intervals and compare. The detail of my matplotlib is below

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
I use Ubuntu 12.04 64 bit version
and

In [3]: matplotlib.get_backend()
Out[3]: 'WXAgg'

In [4]: matplotlib.__version__
Out[4]: '1.2.0'

with best regards,
Sudheer
