Fig 7b is just a set of curves with sequential offsets in x, right?  A 
LineCollection can be nice for this.  See the last panel in 
http://matplotlib.org/examples/api/collections_demo.html.

Hi,

put all them into a list

ps = [p1, p2, ..., pn]

and then unpack them

path.Path.make_compound_path(*ps)

Cheers,

Fra

ps: this is standard python unpacking

Hi, I have several path objects that I want to join together with
make_compound_path.

For example, with p1 and p2:

In [136]: p1
Out[136]: 
Path(array([[-29.85721973, -30.        ],
       [-29.84752676, -29.77715877],
       [-29.88734508, -29.55431755],
       [-29.97470553, -29.33147632],
       [-30.        , -29.28831083]]), None)

In [138]: p2
Out[138]: 
Path(array([[-30.        ,  45.0000166 ],
       [-29.94756898,  45.09749304],
       [-29.87227011,  45.32033426],
       [-29.84525888,  45.54317549],
       [-29.86787108,  45.76601671],
       [-29.93898847,  45.98885794],
       [-30.        ,  46.10595725]]), None)

I can do path.Path.make_compound_path(p1, p2) which joins them successfully.
If I have a another path, p3, I can do:
    path.Path.make_compound_path(p1, p2,p3), and so on.

However, in my script I never know how many paths I will have, so I'd like
 to put them into some sort of container, and pass that to
 make_compound_path.  I've tried lists:


In [140]: p1p2 = [p1, p2]

In [141]: path.Path.make_compound_path(p1p2)
---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
<ipython-input-141-eb62de9fcada> in <module>()
----> 1 path.Path.make_compound_path(p1p2)

/usr/lib64/python2.7/site-packages/matplotlib-1.4.2-py2.7-linux-x86_64.egg
/matplotlib/path.py
in make_compound_path(cls, *args)
    330         total_length = sum(lengths)
    331 
--> 332         vertices = np.vstack([x.vertices for x in args])
    333         vertices.reshape((total_length, 2))
    334 

AttributeError: 'list' object has no attribute 'vertices'


without success.  Can anybody suggest a way to do this?

Thanks, Evan

you could go with something like this:

import matplotlib.pyplot as plt
import numpy as np

fig, ax = plt.subplots(1, 10, figsize=(10,3))
fig.subplots_adjust(wspace=0)

for i,axi in enumerate(ax):
    axi.axis((0,1,0,1))
    axi.xaxis.set_ticks([])
    axi.yaxis.set_ticks([])
    if i is 0:
        axi.xaxis.tick_bottom()
        axi.yaxis.tick_left()
        axi.spines['right'].set_visible(False)
        axi.spines['top'].set_visible(False)
        axi.spines['left'].set_bounds(0, 1)
        axi.spines['bottom'].set_bounds(0, 1)
        axi.yaxis.set_ticks(np.linspace(0,1,5))
        axi.yaxis.set_ticklabels(np.linspace(0,1,5))
        axi.xaxis.set_ticks(np.linspace(0,1,3))
        axi.xaxis.set_ticklabels(np.linspace(0,1,3))
    if i > 0:
        axi.set_frame_on(False)
        
    axi.plot(np.random.rand(10), np.random.rand(10))

Friends,

I want to make multiple graphs on a single axes. As an example, i am
pasting below an article where it has been shown.

http://www.ncbi.nlm.nih.gov/pubmed/23403925

My plot of interest is *Figure7B*, where multiple distribution are depicted
in single plot. I want to make a similar one. Kindly give me some insights
on how i can make it with mpl, if anyone have achieved making it with mpl.

Thanks in advance,
Bala
