matplotlib-users Mailing List for matplotlib (Page 16)

Is there any way to encode 2 variables in a matplotlib colormap?  The idea
is to replicate this dataspora R scatterplot in matplotlib:

http://www.dataspora.com/gameday/pitcher/daisuke-matsuzaka/493137

"The bottom strip of charts encode two dimensions with color -- blue or red
hue indicates pitch velocity -- while the lightness or darkness of the hue
indicates how many pitches were thrown in a given region. "

I am generating level curves numerically with a gradient method of my own
recipe.  The result is a bunch of 100x2 vectors, each 'row' of which is a
point on a level curve in the plane.  My goal is to label each plot line
analogously to how contour lines are labelled with clabel.  Is this
possible?  If so, does anybody know how or have some example code?

Thanks,
~Luke

Jose: I think the key is to only create the basemap instance only once 
(for the main plot and for the inset), then re-use that basemap instance 
each time you create an animation frame.

I just upgraded from 0.98.3 to 0.98.5.2 on my Mac (OS X 10.4.11) because I
wanted some of the new legend features, and now have two strange errors.

1) When I run a script that creates a plot, the terminal window (either a
command prompt or ipython) is now frozen until I have closed the plot
window.  Previously, this same script would create the plot, but then allow
me to access the prompt.

2) I seem to no longer be able to zoom in or out on the plots.
Additionally, with 0.98.3 I used to be able to dynamically move the plots (I
would see the figure move as I dragged it), but now the plot doesn't move
until after I've released the mouse button, making it harder to see how far
I've moved it.

I've noticed that my old backend was 'TkAgg', while 0.98.5.2 defaults to
'MacOSX'.  I've tried running

matplotlib.rcParams['backend'] = 'TkAgg'

at the top of my script, but that doesn't seem to do anything (I have the
same problems).  Does anyone have any idea what's happening or how I can fix
these problems?  If not I may need to go back to 0.98.3 for now.  Thanks.

Hi!

[I think the message didn't get through the first time I sent it. Resending,
and apologies if you get it twice]

I have a rather complex basemap-derived plot that I want to save as
animation.
In essence, it uses the blumarble() to add a nice background, plots some
stuff on top of that, and also has an inset with a map of the world that
shows the area of the main map.

The problem is that memory usage as I iterate through the frames that will
eventually make up my animation, rises very fast. I read a post some time
ago
on how to store the background, so it didn't have to be recreated everytime
here:
<http://www.nabble.com/Save-a-plot-background-to20519596.html#a20519596>

There's an example on how to actually do this for basemaps from J Whitaker,
but I can't get this to work on my example. Ideally, I would like to store
the inset in a function, and my main background in another function, and
restore each axis directly. My attempt follows (which produces a blank
image)
is at <http://pastebin.com/f4636fd7f>

Unrelated to your original question, is there a reason you need axes_square
there and can't just use:

ax.set_aspect('equal')

?

Try this:

from matplotlib import pyplot as plt
from matplotlib.patches import Circle

f = plt.figure()
ax = f.gca()
rad = 1.4
c1 = Circle((-1,0),rad, alpha=.2, fc ='red')
c2 = Circle((1,0),rad, alpha=.2, fc ='blue')
c3 = Circle((0,1),rad, alpha=.2, fc ='green')
ax.add_patch(c1)
ax.add_patch(c2)
ax.add_patch(c3)
ax.set_xlim(-3,3)
ax.set_ylim(-3,3)
plt.show()

Such a shame... Anyway, I'm glad to learn horizontal bars are possible, I'll
try it.

Internally, we often do end up using Nx2 ndarrays.

I don't think it makes sense to complicate the API by directly 
supporting other function signatures, however, if this is what you are 
proposing.  For example, we have plot(y) and plot(x,y); to support 
either of the alternatives you mention above would require either a 
kwarg or a different function name.  Personally, I would rather leave it 
to the user to take care of this as needed, and keep the additional 
complexity out of matplotlib.

Yes.  To begin, see examples/event_handling/pick_event_demo.py and 
pick_event_demo2.py.

On the web, the code is here:
http://matplotlib.sourceforge.net/examples/event_handling/index.html

In working on code for matplotlib, I would generally find it easier to  
provide an array of objects than to provide an array of X values and a  
second array of Y values. I understand that X[] and Y[] is the way  
that matlab does it, but we would find it easier to provide an array  
of either tuples  [(x1,y1), (x2,y2), ...]  or else an array of objects  
with .x and .y properties.

Other than doing our own cover, is there any other way to do this? Any  
thoughts of adding this functionality?

-Simson

Greetings.

I have a colleague who I have worked hard to convert from matlab to  
matplotlib.

One issue that has come up is clickable graphs. He would like to be  
able to click on the graphs that matplotlib produces and actually have  
things happen. For example:

* Display information about a histogram, like the values that went  
into the bin.
* Have a callback called with information about where the click took  
place.

Is there any way to do this?

hi all,

can someone advise on how to make simple venn diagrams, like the one here:

http://en.wikipedia.org/wiki/File:Venn_diagram_cmyk.svg

simply three (or more) intersecting circles, such that one can label every
point of their intersection, and maybe make the circles in size proportion
to the number of elements they are supposed to represent.  i know some
people use Sage for this but i prefer to use matplotlib directly.

any help / info on how to get started on this or some example code would be
greatly appreciated.

thank you.

Width is in the same units as x, and it looks like your range of x 
values is 1e8, so maybe your width needs to be something like 1e7, not 10.

Horizontal bar is possible, although i'm not sure it fits your need.

http://matplotlib.sourceforge.net/examples/pylab_examples/barh_demo.html

Anyhow, with the current mpl, I guess it is much easy to make the
horizontal bars with rectangle patches (in case barh does not do what
you want), rather than trying to rotate the legend.

hi all,

i am reading a set of tab-separated data from a file and i want to put it
into an array, and then plot some of the columns. i know the number of
columns ahead of time but not the number of rows. i load the array from the
file as follows, which seems to work:

data = []
for line in myfile:
  field1, field2, field3 = line.strip().split('\t')
  data.append([int(field1), int(field2), int(field3)])

i then convert it into an array as follows:

data = array(data)

i am able to reference the first column as follows:

data[:,0]

but if i try to plot the first column against the second as follows:

bar(data[:,0],data[:,1])

then i get the error:

/usr/lib64/python2.5/site-packages/matplotlib/units.pyc in
get_converter(self, x)
    128             converter = self.get(classx)
    129
--> 130         if converter is None and iterable(x):
    131             # if this is anything but an object array, we'll assume
    132             # there are no custom units

[repeated many times]

RuntimeError: maximum recursion depth exceeded
WARNING: Failure executing file: <myfile.py>

how can i fix this? i'd like an n-by-m representation of my data as an array
which i can reference like a matrix in matlab. some of the columns are
floats, other are ints, and others are strings, so i prefer to load the data
into an array as a loop where i can cast the strings appropriately, rather
than use some built in io function for reading tab-separated data.

thank you very much.

I don' think these is a straight forward way to rotate the legend as a whole.
As a matter of fact, it is hardly possible with the current
implementation of the legend class. Could you explain why do you want
to have a rotated legend? An example figure (from other plotting
package) will be very helpful. If a rotated legend is desirable, I'll
work on to support it.

Regards,

-JJ

Linux v.s Mac does not make much sense. What version of maplotlib do
you use in each platform? The rc file in two platform are identical?

They are both pdf files, it does not make much sense that one of them
has a higher quality. Looking at your two pdf files, the ticks in
linux.pdf looks a bit more fuzzy, but as far as I can see, it seems to
me as some antialising effect.

If you think the tick lines are too fuzzy, you 'd better increase the
width of tick lines.

 rcParams["lines.markeredgewidth"]=1. # default is 0.5

I don't think there is nothing wrong with the mac version. But see
below. Again, if you think the tick lines are too fuzzy, increase the
line width.

Are the linux.pdf and mac.pdf created with a same script?
The linux one seems to have xrange of -0.05~1.05 while the mac one has
x-range of -0.05~1. And according to your script, it should be
-0.05~1.

What do you intend to do by "xlim(-0.05, 1, 1.05)"? Why you a third
arguments?  (I don't think you mean to set emit=True by this).

Maybe you just wanted "xlim(-0.05, 1.05)"?
