In SVN trunk, there is an example in examples/event_handling/viewlims.py
that redraws a fractal when you zoom in. You could probably adopt a similar
approach to grab new data points, though the details would depend on the
type of plot.

Me and my team are almost to the finishing point. Our final problem is
getting the graph to update.

Dear Matplotlib Folks,
When I run pylab.plot, I get a weird warning:
** (python:20754): WARNING **: Couldn't connect to system bus
** (python:20754): WARNING **: Couldn't connect to system bus
<matplotlib.lines.Line2D object at 0x1225850>
(Note that this was copied by hand because the system on which I run
Matplotlib is currently unable to connect to the global internet.)
The first line really is repeated.
The number after "python:" changes from one instance of the warning to
another.
I am running:
Red Hat Enterprise Linux ES release 4 (Nahant Update 3)
At least, that is what is in /etc/redhat-release.
The warning is not fatal and I can display what I attempted to plot with
pylab.show. However, the warning has a significant impact on the
interactive usability of Python and matplotlib as a replacement for Matlab.
Anyone have any suggestions or observations?
Yours,
David Sigeti

Mike: To save space, the EPD folks took out the full resolution 
datasets. Manually copying the files should work - are you sure you got 
them in the right place (the mpl_toolkits/basemap/data directory)? You 
probably have to copy more than the gshhs file (the states, rivers and 
countries too).

I am experimenting with the Enthought Python Distribution (EPD) on MacOS 
10.5, which includes BaseMap version 0.99.1. I have existing modules 
that use the 'full' resolution data. These modules are currently 
failing with the error message below.
I have tried copying what looked like the full resolution data sets 
(gshhs_f.dat and gshhsmeta_f.dat) from my 0.99.2 source installation 
into the EPD basemap data directory, and rerun my scripts, with no success.
I looked at my most recent copy of the basemap README and cannot find 
any reference to the boundary datasets.
So, a question for Jeff, and a request for Enthought:
1) How do I update the EPD with the full resolution data
2) Can the EPD be updated to include the full resolution boundary data?
Thanks,
Mike

I've got the NavigationToolbar2 going nicely on my app
(OO, embedded in wx, mpl 0.98.5), and was wondering
how difficult it might be to change how the pan works,
in the following way...
Right now, when I show a plot, I am grabbing a subset
of data from the database. Panning within that plot
allows exploration of *just that data*. E.g., if I have
values between x = 100 and x = 200, I can pan past
either of these values, but there are no more data points
beyond that, because I didn't fetch those points when I
created the plot.
What would be nice is if, on panning, I could fetch
new points, namely those that are found in that part of
the x axis. This would be just like Google Maps' ability
to allow one to pan the map over and see new land area,
because it fetches those land patches of the map.
I could of course just fetch all the data I have first
and set the x limits to show the requested subset
of data initially, but I thought maybe it would
be more efficient to only get what is requested and
then grab more data on pans. I thought I'd ask if
anyone had done something like this already.
Thanks,
Che

As Darren said, normed=1 means that the integral of the histogram is
normalized to one, not the height. In other words, the total area under the
histogram curve is set to one.
Imagine a histogram with a single bin. If the width of the bin is less than
one, the height must be greater than one in order for the area to equal one.
Therefore the y-axis scale can be greater than one even when normed=1.

There was a typo in my previous mail.
y axis goes scale is more than one when i use normed=1. I am not getting why
this happens.

Sorry, I'm not sure what "filling the width of the x-axis" means or what you
are expecting to see. If you want to the x and y limits to be collapsed to
your data limits, you need to do
 ax.axis('tight')
JDH

My graph, which had been working just fine, randomly decided to stop filling
the width of the x-axis: http://screencast.com/t/vr3AaXIq
Here's the code I'm using (nothing fancy.. I took out all unnecessary
formatting and it didn't help):
fig = plt.figure(facecolor ='w', frameon=False)
ax = plt.subplot(111)
lines = ax.plot(r_dates, r_inbox, 'w-')
I'm out of ideas.. what could be causing this?
Thanks!

which kind of data file? ascii? If yes, numpy.loadtxt will be your friend.

Hi,
I'm using the code copied straight from the simple tkagg animation example at:
http://matplotlib.sourceforge.net/examples/animation/simple_anim_tkagg.html
It starts up fine and I can see the moving sine wave, however, after about 15 to 20 seconds the plotting window freezes showing "Figure 1 (Not Responding)" and that's that. Adding an additional line, "print i" just before "line.set_ydata(...)" shows that even once the window has frozen the code is still being executed. Has anyone had this problem and solved it?
I'm on Windows Vista running:
Python 2.5.1 (r251:54863, Apr 18 2007, 08:51:08) [MSC v.1310 32 bit (Intel)] on win32
Matplotlib v0.98.3
numpy v1.2.0
Tkinter $Revision: 50704 $
Thanks

I am using 0.98.3-3, which is in the Ubuntu packages.

You have to call plt.show() only when you want to actually show the
figure. That's because you're using python command interpreter.
Try:
plt.plot(x,y,'b-')
plt.ylim( (1.5,4.5) )
plt.show()
If you want to do interactive plotting, I suggest using ipython.
ipython -pylab
already import the pylab module, that provide all the pyplot functions.
I prefer to do something like
$ipython
 import matplotlib.pyplot as plt
 plt.ion() # incase it's not already in interactive mode
 <do my printing>
This way, it will open the figure window and you'll be able to
"decorate" the plot in the ipython shell and see the result applied to
the "background" figure with no need to execute "plt.show()" or close
the windows between a command and a "show()".

Friends,
In the following. I am not able to understand how this plot.show() works. I
have commented the problem in the following examples.
>>> plt.plot(x,y,'b-')
[<matplotlib.lines.Line2D object at 0x9e50ecc>]
>>> plt.show() *# shows the plot of x Vs y*
>>> plt.ylim( (1.5,4.5) )
(1.5, 4.5)
>>> plt.show() *# Does nt show the plot*
>>> plt.ylim( ymin=1.5,ymax=4.5 )
(1.5, 4.5)
>>> plt.show() *# Does nt show the plot*
Thanks,
Bala

Friends,
Kindly give me some tips on how to import data from a data file to make the
plot.
Thanks,
Bala

Ok so at least you can reproduce with bug ;)
Maybe we should ask matplolib to render into a buffer widget...but I not
sure.
However, I'm pretty sure we should not call matplotlib on every draw event.
Any ideas??

I suggest you to have a look to the matplotlib gallery, in particular
this example 
http://matplotlib.sourceforge.net/examples/pylab_examples/psd_demo2.html
You need to define subplots using the pyplot interface
http://matplotlib.sourceforge.net/api/pyplot_api.html?#matplotlib.pyplot.subplot
or the matplotlib API 
http://matplotlib.sourceforge.net/api/axes_api.html?#matplotlib.axes.Subplot
With many subplots, you may pay attention with the figure size, that you
can define with the 'figsize' and 'dpi' keyword arguments of the figure
function :
http://matplotlib.sourceforge.net/api/pyplot_api.html?#matplotlib.pyplot.figure

This is covered in the tutorial I referred you to in my first response,
 http://matplotlib.sourceforge.net/users/pyplot_tutorial.html
specifically the section "Working with multiple figures and axes"
http://matplotlib.sourceforge.net/users/pyplot_tutorial.html#working-with-multiple-figures-and-axes
To make six rows and three columns, you do
 subplot(6,3,1)
 subplot(6,3,2)
 ...
 subplot(6,3,18)
See also the documentation for the subplot command
http://matplotlib.sourceforge.net/api/pyplot_api.html#matplotlib.pyplot.subplot
