Use pylab.load to load the data into an array. Then, the rest of what
you want to accomplish is detailed in the wiki:
<http://www.scipy.org/Cookbook/Matplotlib/Maps>.
Hope that helps!

if you're building an app i would suggest using the OO interface.
There are good examples in the examples directory. But basically you
get a figure either by constructing it or using pylab.gcf and you can
add_axes to the figure and plot on them. It is much more scalable for
an app than the pylab interface.
as for your original question, i'm afraid i've never seen the behavior
before and don't have a good answer.

It's definitely not the behavior I'm seeing here. In my matploblibrc file,
hold is set to True. Is there another value that might be influencing this?
In any case, I don't want the behavior to be dependent on a config file: I'm
building an application. Do you know how I might specify this behavior at
run-time?

I have several lines of data that I want to plot on the same graph, but
every time I run the pylab.plot() function it redraws the graph from
nothing. I've tried pylab.plot(*, hold=True) and pylab.hold(True), but it
still happens. Can I add data to an existing figure, or do I have to pass
all the data at once?
e.g., Do I have to do this:
pylab.plot(x1, y1, x2, y2, x3, y3, ...)
or can I do this:
pylab.plot(x1, y1)
pylab.plot(x2, y2)
pylab.plot(x3, y3)
...

Matt, just to let you know, axes3d is not really supported. We
include it because some people find it useful and we're hoping some
person (you!) will pick it up and run with it. This code was written
and generously donated by John Porter, who is too busy to maintain it
as are the other core mpl devels. So please use it and post problems,
but don't be surprised if noone comes to your aid. Most likely, you
will need to find and fix these bugs yourself as you can.
In general, you can turn off autoscaling with 
 ax.set_autoscale_on(False)
Though I would have to dig through the code to see if this is
supported for Axes3d....

Hi!
I am farely new to matplotlib and basemap. I have one question about how to plot data from a csv file on a map.
the header goes as this
ID lat(x) long(y) measurements(z)
how can I read data in that
x gets the latitude
y gets the longgitute
z gets the data which will be shown in different color accoring to their values?
I played around and started from quiver_demo.py but didn't find my way.
reader = csv.reader(open('t.csv'))
for row in reader:
 print row
Could you give me some hints or starting points?
Thanks,
Tim
