Jim:  Using 'zorder=0' when calling the Basemap plot method seems to do 
the trick.  Perhaps I should add a 'zorder' keyword to drawcoastlines as 
well (there already is one for fillcontinents).

The code at the end of this message is a toy example which shows the  
problem I am encountering.
OS X 10.4.9  basemap 0.9.5 (Numeric 24.2 and Numpy 1.0) python 2.5

I define a map projection using Basemap, and then plot a number of  
markers at various geographical locations.
I would like the map coastlines to overlay the marker symbols, that  
is write over them as they pass through them.
I cannot get the coastlines to overlay the markers, no matter what  
the calling sequence. The markers always obscure the coastlines.

In the basemap/example contour_demo.py, the coastlines are called  
after contourf and the coastlines appear over the filled contours.
So there seems that there is something different in the plot marker  
characteristics.

I am probably missing something obvious - but what?

For example with:

  hlines(0,-1,1)
  vlines(0,-1,1)

I did reinstall my python with Python 2.5.1, Matplotlib 0.9, wxpython 2.8.4
and then it now works.
Thanx
Best Regards

hello,
the following script correctly plots the 2D exponential, but when I put 
my mouse on it, matplotlib sends this exception on the terminal :

the script is :

X, Y = meshgrid(x,y)

ax = p3.Axes3D(fig)
ax.contour3D(X,Y,Z)
ax.set_xlabel('X')
ax.set_ylabel('Y')
ax.set_zlabel('Z')
show()

Am I doing something wrong?
thanks,

Hi Robert,

If your app is wxPython based then I would use the attached as a test 
case and not the simple_plot one.

Then if you don't use wxPython Unicode 2.6.x then you need to follow 
Andrea's work around.

matplotlib/backends/_wxagg.pyd

to

matplotlib/backends/_wxagg not used.pyd


Hope this helps
Werner

Hello Werner, 
 
I run on WinXP with 
matplotlib 0.9.0 
python 2.4.3 (enthought edition) 
wx.VERSION_STRING = 2.6.3.3 
 
 
I tried your small example to use your setup and your simple_plot but i  
get the following traceback: 
 
    Traceback (most recent call last): 
      File "simpletest.py", line 6, in ?

    AttributeError: 'NoneType' object has no attribute 'splitlines' 
 
    Did I miss something? 
 
    Actually I am also trying to understand how to py2exe my own app. 
 
    Thanx for help.

 Hi Giorgio, 
 
Had a quick look at pylab based scripts and got an error on  
backend_tkagg when py2exe it.  It looks like one needs to force the  
backend to be included, I used tkagg but you would have to replace that  
with wxagg for your script. 
 
Attached is a setup.py and from the examples the file simple_plot.py.

Me too, on Linux, mpl 0.90dev3131. If it's adding a constant border of 6 on two
sides, can you tell mpl to export e.g. 588x288 (more hack than solution, though...)?

I'm trying to get matplotlib to make a 600x300 png, but matplotlib won't
let me; it keeps making a 612x312 png instead.  Here's a sample script
that has the problem on my system:

figure(figsize=(6., 3.))
plot(arange(10))
savefig('test.png', dpi=100.)

If I set dpi to 50., it makes a 312x162 png.  It appears to be adding a 6
pixel border to the edge of all the pngs.  How do I get rid of it?

Windows XP SP2, Python 2.5, matplotlib 0.90.

I'm going to advise you to not try to do that. MPL really isn't a GUI 
toolkit, there there are a number of very nice and complete GUI toolkits 
that MPL works just great with. It will require a bit of learning up 
front, but you'll get a much better result, and probably less pain in 
the process. My thoughts:

For Cross platform (Windows, *nix, OS-X): wxPython or pyQT. Tk's OK too, 
but at least until recently, not very native or robust on OS-X.

For *nix only: PyGTK

For OS-X only: Maybe pyObjC, but only if MPL is working OK with the 
Cocoa back-end -- or has development stalled there?

See the "embedding in ..." examples, and be sure to check out wxMPL if 
you want to use wxPython.

Hello everybody,

I tried useing matplotlib as a GUI for my programs. I'd like to incorporate 
things like Buttons, Sliders, RadioButtons and so on from 
matplotlib.widgets, but missed a prompt (i.e. a field to input text and/or 
numbers).

My question is: Is there already a text-input-field in one of the mpl modules?

Best regards and thanks in advance for any hints,

Jeff, 

This "_r" command seems not work well. Let me show you the full
line of that color map plot,
 --------------------------------------
contourf(X, Y, Z, v1, cmap=cm.pink)
 -------------------------------------- 

By the way, Jeff, do you know how to make the cmap explicitly defined,
like in GNUPLOT,
 ----------------------------------------------------------------
set palette defined (0.004 "white", 0.17 "brown", 0.28 "black")
 ---------------------------------------------------------------- 

Thank you so much!

Hi,

I'm wondering how to use matplotlib to 
plot on axes that intersect at the 
origin, as in the following picture:

              |
              |
	      |
              |
              |(0,0)
----------------------------
              |  
              |
              |
              |
              |

Any help will be appreciated

Michael.

Teng:  Simply append '_r' to the colormap name to get the colors 
reversed (e.g. cmap = pylab.cm.hot_r instead of pylab.cm.hot).

Hello, I have a quick question for you. 

I was trying to make a color and contour plot. But the problem is that
the matplot defaults the colors from the dark to light for the contour
values from minimum to maximum, is there any way or commands to reverse
this order? I mean the dark color for maximum value and light color for
minimum. 

Thank you so much!

See the chapter on mathtext on page 32 in the user guide:

That is described on page 52 in the user guide (see listing 6.1 for an 
example).

Hope this helps.

Hi All,

I'm trying to respond to double-click events on axis labels and tick
labels.  I'm using the wxAgg backend, and matplotlib directly, not
through pylab.  The matplotlib panels are wrapped into a bigger program.

Based on an thread between Andrea Gavana and Chris Barker back in Feb
06, I hacked a double-click event into backend_bases.py and
backend_wx.py.  This seems to work as expected; I can capture the double
click events without any problem.  Now for capturing pick events, the
built-in pick function seems to rely on the selection being "inaxes" so
I borrowed heavily from the object_picker.py demo to capture selecting
the tick labels or the axis labels.

My concern is that I'm reinventing the wheel.  Being able to capture
picks of the various labels seems like a natural thing to want to do
(e.g. for modifying font properties, display format, etc).  Is there an
easier (erm, and better!) way to accomplish what I've done?

Thanks,
Anthony.

hello, I'm tinkering with my matplotlibrc file and the changes are not taking effect. specifically I'm changing the hspace and wspace between subplots... although none other options seem to take effect either. I put the matplotlibrc file in my working directory with my script. I also tried making changes to the matplotlirc file in the installation directory, this didn't work either. should pylab be looking in the working directory for matplotlibrc? If so, what might be a reason changes aren't taking effect?

thanks,
Jeff

Look into the arguments of the xticks function.  I do things like

tickvals = arange(5.998,6.0025,0.0005);
ticklabs = map(lambda val:"%.4f"%val, tickvals);
ticklabs[0::2] = map(lambda val:"%.3f"%val, tickvals[0::2]);
xticks(tickvals,ticklabs);

to customize.

matplotlib supports mathtext strings, like  r'$\Phi_0 = e^{i\pi}$'. Currently, 
if you want to mix mathmode and regular mode, r'for example: $\Phi_0 = 
e^{i\pi}$', you need to enable usetex in your matplotlibrc file. usetex 
requires latex, ghostscript, dvipng to be properly installed, see 
http://www.scipy.org/Cookbook/Matplotlib/UsingTex for more details.

That's a new problem. Eric, it looks like some of your recent changes to 
ticker.py had some unintended side-effects. Do you have time to look into it?

Hi, I'm fairly new to using matplotlib having just stopped using Matlab
and started using Python.

=20

I have two questions about matplotlib.

=20

1)  It's pretty easy to include text on a graph, but are LaTex strings
supported?  That is, I want to write something like this on my plot:
'\Phi_0 =3D blah...'.  When passing a LaTex command as part of text =
string
to be written on a plot in MatLab, it interprets this and displays the
(in this case) Greek symbol.  Any suggestions on how this is or should
be done with matplotlib?

=20

2) How do I format how tick mark labels are displayed?  I have a plot
whose x-axis runs from 0 to 8.5e-5.  But the tick mark labels are
0,0.00001,0.00002,0.00003...  This is rather unsightly, but I haven't
found a way to specify the format of these numbers. =20

=20

thanks for any help,
