matplotlib-users Mailing List for matplotlib (Page 8)

On an iMac running 10.6.3, python 2.6.4 I have installed numpy and then matplotlib using 'pip'.
The message in both cases was that the install was successful.
'import matplotlib' does not cause error messages.
'from pylab import randn, hist' gets a traceback with the message "ImportError: No module named ma"
How do I get matplotlib to work?
Thank you for any help.
Christopher

Hi,
I would like to set the limits of the x axis and get the y scale
adjusted to the new range. I have tried something like
plot.axis('tight', xmin=0, xmax=1), but this shows all the data as
indicated in the documentation. Is there any way to limit the x axis
and set the y axis to tight?
Thanks,
Miguel

Dave,
Thanks, but much as I would like to see this problem solved, I don't 
really want to get sucked into it. I haven't messed with Suns for many 
years, and I am not eager to resume.
Did you compile the previous version of matplotlib that you used on your 
machine, or did someone else there do it?
Have you looked at the Cookbook entry?

I did reply, but I think off-list by mistake. So I'll reply to the list.
I think this actually causes the build to break earlier.
Do you have access to Sun SPARC hardware? If not, I can almost certainly arrange 
access to a Sun T5240 (16 core) at the University of Washington for a serious 
matplotlib developer.

Can you get it to work by adding "-D_XOPEN_SOURCE" to your CFLAGS 
environment variable?

I'm relatively new to matplotlib so I need some help. I'm trying to make a
direction field plot for visualzing solutions to differential eqs. My first
attempt at a simple plot came out all right but I can't figure out why the
plotted lines are not the same length. The block of code that does all of
the work is...
for x in ax1.xaxis.iter_ticks(): #Iterate
over x-ticks
 for y in ax1.yaxis.iter_ticks(): #iterate
over y-ticks 
 
# Solve for local slope at point to be evaluated (dy/dx)
 yp = 9.8 - ((np.float(y[1]))/4) #yp = y` as
in dy/dx
 
 
# Plot line based on slope
 cpx = np.float(x[1]) #cpx = x-coord of line center,
convert x-tick value to float
 cpy = np.float(y[1]) #cpy = y-coord of line center,
covnert y-tick value to float
 
 a = np.arctan(yp) #a = angle between line and
horizontal
 
 
 px = np.cos(a)*(L/2) #px = x offset from line center to
end
 py = np.sin(a)*(L/2) #py = y offset from line center
to end
 tpx = cpx + px #tpx = x-coord of right hand
end of line
 tpy = cpy + py #tpy = y-coord of right hand
end of line
 bpx = cpx - px #bpx = x-coord of left hand end
of line
 bpy = cpy - py #bpy = y-coord of left hand end
of line
 
 Length = np.sqrt(((tpx-bpx)**2)+((tpy-bpy)**2))
 #just a quick check of the line length accoring to the coordinates of
the ends
 ax1.plot([bpx, tpx], [bpy, tpy], color='black', linewidth=0.75)
As you can see in the attached figure (see below), the lines seem to plot in
the right locations and right angles but the lengths are not constant (not
intended - seem to be twice as long near the middle of the chart). Am I
missing something obvious? Why are the lines near the center of the chart
longer? Thanks in advance for any help provided.

The latest stable (0.99.3) matplotlib builds ok on Solaris 10 03/05 on SPARC.
However, your latest trunc release has some useful fixes, so it was downloaded 
by a fellow Sage devloper. However, when I try to build this version on a Sun 
Blade 1000 running Solaris 10 03/05, it presents a problem:
/usr/include/stdlib.h:144: error: declaration of C function 'void swab(const 
char*, char*, ssize_t)' conflicts with
/usr/include/unistd.h:480: error: previous declaration 'void swab(const void*, 
void*, ssize_t)' here
error: command 'gcc' failed with exit status 1
Error building matplotlib package.
There are two declarations of 'swab' in the Solaris header files, and what one 
you get depends on the compilation mode. The reasons are explained in the 
Solaris header files.
The issue is traced at
http://trac.sagemath.org/sage_trac/ticket/9202
where you will see the full error message and attachments of the header files.
For this, gcc 4.4.4 was used.

Hi Everyone,
I'd like to know, what is the underline mechanism that connects the points
of my gridded data when I use
contour().
Can I control this mechanism ?
Maybe I missed it in the documentation, but it's not clear to me.
Thanks in advance,

Clearing the font cache works too. Although, judging from the debug output,
it still seems to find the fonts in the system directories. There are no
fonts in the matplotlib site-packed dir:
[jsp@psy86] 1014:$ ls
/usr/lib64/python2.6/site-packages/matplotlib/mpl-data/
example/ images/ lineprops.glade matplotlib.conf matplotlibrc
I installed matplotlib with gnome package kit from the fc12 repos. I
manually installed stix only after seeing this problem (after my font cache
was already hosed).

The transformation must take input in your coordinate system and
output in display coordinate systems. The default Affine2D
transformation is identity, so you are transforming 0.5, 0.5 userland
coordinates to 0.5, 0.5 display. This display coordinate falls
outside the Axes window and so is being clipped. If you turn clipping
off, you will see part of your text in the lower left
t = Text(0.5, 0.5,"Problems?",transform=mytrans, clip_on=False)
If you want to see it in the middle of your plot, you could do something like
t = Text(200, 200,"Problems?",transform=mytrans, clip_on=False)
Note this transformation applies only to the x,y location of the text,
and will not transform the glyphs of the text.
See http://matplotlib.sourceforge.net/users/transforms_tutorial.html
for more details on transformations.

Ola,
Just to make sure, have you tried "ax.set_xticks([])"?

Hello all.
I'm trying to apply a transformation (Affine2D) to a text artist. For
some reason the artist doesn't show up in the plot. I have a simple
code here which demonstrates the problem. Any ideas what I'm doing
wrong?
Thanks
Jack Liddle
from numpy import *
import matplotlib.pyplot as plt
from matplotlib.text import Text
fig = plt.figure()
from matplotlib.transforms import Affine2D,Transform
ax1 = fig.add_subplot(111)
#Something to plot
xs = linspace(0,1,100)
ys = xs**2
ax1.plot(xs,ys)
#The transformation
mytrans = Affine2D()
print mytrans
print isinstance(mytrans,Transform)
t = Text(0.5,0.5,"Problems?",transform=mytrans)
ax1.add_artist(t)
plt.show()

The problem here is that it isn't finding the STIX fonts in the 
matplotlib distribution, but from system locations -- and it's actually 
not finding all of them, only some.
How did you install matplotlib? Did you try John's suggestion of 
clearing the font caches? Do you see any STIX ttf fonts under
/usr/lib64/python2.6/site-packages/matplotlib/mpl-data/fonts/ttf
?

 mathtext.fontset : stix

You may also want to clear your fonts and tex cache
 rm -rf ~/.matplotlib/font*.cache
 rm -rf ~/.matplotlib/tex.cache
though this is probably not the source of your problems....
JDH

Can you set the rcParam 'verbose.level' to 'debug-annoying' and send us 
the output?
What version of matplotlib? Which backend?

 Hello!
 I wonder if there is a way to make 3d plots specifying arbitrary
colors, instead of having the color be a function of the height. I was
able to achieve this making minimal changes to the plot_surface method
of Axes3D, adding as an optional keyword argument a function *cfun*
which specifies the color (it specifies a real number that is mapped
into a color by the color map *cmap*). But is there a standard way?
 Regard
Pablo Angulo
from matplotlib.colors import Normalize, colorConverter
def plot_surface(self, X, Y, Z, *args, **kwargs):
 '''

Hi,
I'm trying to remove the xtickmarks and ytickmarks from a 3d plot,
without any success.
The example I experiment with is the following:
from mpl_toolkits.mplot3d import axes3d
import matplotlib.pyplot as plt
fig = plt.figure()
ax = axes3d.Axes3D(fig)
X, Y, Z = axes3d.get_test_data(0.05)
cset = ax.contour(X, Y, Z, 16, extend3d=True)
ax.clabel(cset, fontsize=9, inline=1)
#One try that didn't work
ax.set_xticklabels("")
plt.show()
It looks like the final plot ignores all my efforts in turning the
ticks off. Any help on this matter would be greatly appreciated.
Regards,

Ben: I've added a new example (fcstmaps_axesgrid.py) that does this.

Hi,
yes as I understand it (happy to be corrected)...
fig = plt.figure(figsize=(8, 4))
fig.subplots_adjust(bottom=0.05)
does nothing unless you also do 
ax = fig.add_subplot(111)
but as I am also doing 
ax = fig.add_axes([0.1, 0.15, 0.7, 0.7]), it means I would just get two
frames.

Not that it was a "problem" per se, just merely an observation I had.
Anyway, I tried that and indeed, zooming on one box zoomed all of the other
boxes the same way. Might be good to include in the basemap examples,
maybe?
Thanks,

Just to make sure, were you calling subplots_adjust() *before* calling
subplot()? Calling it after subplot() shouldn't have an effect on the
already created axes (I think...).

Unless I am mistaken subplots_adjust doesn't do anything as I am building an
axes instance. Doing...
fig = plt.figure(figsize=(8, 4))
ax = fig.add_axes([0.1, 0.15, 0.7, 0.7])
has shrunk the white space, though I think the font of the legend looks a
bit less well defined, but perhaps that is just my eyes!

When I run the following, I get gibberish for the math symbols: ),?,"
instead of alph's, beta's, ..., etc.
I believe I have all the correct fonts installed: stix, computer
modern. I have tex and latex installed.
Any suggestions? I am running FC12.
Thanks,
Jeff

Just in case nobody responded to you, yet...
Are you asking how to plot a trend line onto a figure already containing
data, or are you asking how to calculate a trend line from the data? If you
need to calculate a trend line, then you need to use the SciPy module. If
you already have your trend data, then you can call plot(X, Y) after you
call your other command to plot your data.
