Hi,
I often do this with ds9 and funtools.
ds9 is an astronomy-oriented image viewer (http://hea-www.harvard.edu/RD/ds9/)
but you can also use it with numpy array.
Within ds9, you can define regions (ellipse, polynomial, etc) easily
with a mouse.
After you define a region (and save it as a file),

Really? Try
plot([1,2,3], lw=math.pi)

Hi, does anyone know of a way to create lines with variable thickness and
color when doing a plot?
Basically, I'd like to have a third dimension represented using thickness.
The API for the plot function states that the line thickness can only be a
single floating point number.
Thanks

Okay, thanks to Ryan, I now have this point fixed,

Matplotlib users,
I've been using pcolor and pcolormesh to plot results from the NCEP
Reanalysis. I've noticed that the plotted values are slightly offset.
Googling around I see that matlab has this quality, which I assume
matplotlib inherited.

.get_paths() returns a list of Path objects. (See path.py). For each
Path object, you can get an Nx2 array of vertices from its "vertices"
member. You can also use the "iter_segments" method to iterate through
each of its vertices, but that's primarily only useful when there may be

I've successfully plotted gridded data on a basemap "cyl" projection

Hello,
I'm using a svn version of matplotlib and the API changed for contour. I want
to have the coordinate of the contour. Before Eric Firing (I think) gave a
solution to do it:
val = contour(xRange,yRange,delchi2,[1])
t = asarray(val.collections[0].get_verts())
but now get_ve

Okay, that tells me that I prettymuch don't want to be using show(), but
I don't think I want interactive mode either...

This didn't work :-S
- the first time I call show(), execution never comes back to my script
so the code never gets to plot any further points

I suspect there is an .afm font file on your new system that is untested
with matplotlib and exhibiting something "new".
I would first try to track down which font file it is, and then send it
to me off list and I'll have a look at what might be tripping up matplotlib.

I'm getting a nonsensical error when attempting to make a simple plot
with a date axis. Googling shows this similar errors, but none with a
date axis. What could be causing this?
