[Matplotlib-users] handling pick events doesn't work for me
Hi
I have a GTK application with the code
def on_pick(event):
print on_pick
thisline = event.artist
xdata, ydata = thisline.get_data()
ind = event.ind
print 'on pick line:', zip(xdata[ind], ydata[ind])
cid = fig.canvas.mpl_connect('pick_event', on_pick)
but the routine never gets called when I click the left mouse button.
Instead, the FigureCanvas pick method is called.
What am I doing wrong??

Re: [Matplotlib-users] display a filled lat/lon basemap rectangle.
lets say I want to shade the area with lat/lon corners 34.-117 and 35,-116 but my map was created with projection='aeqd' The shade area will not be a rectangle. In fact the edges will be curved. See the basemap code for tissot. I think every point on the boundary of the lat/lon box has to projected to a line segment. The collection of resulting segments forms an irregular polygon.

[Matplotlib-users] another noob question
Any help appreciated I am displaying a line on a map ala -- m=Basemap( ) xpt,ypt= m([],[]) outlines=m.plot(xpt,ypt,'r-') - and then in an update routine I do def update(newxpts,newypts): outlines[0].set_data(newxpst,newypts) --- This works fine but now I want to add additional lines.

[Matplotlib-users] how do I get my axis
Okay, I've gotten this far. I have a Figure and I think I can change the formatting of the values displayed in the toolbar by setting taking the X axis and setting the function format_xdata to something of my own (something that computes lat/lon). Similar idea for the Y axis. So, given my figure, how do I get the X and Y axis? All I see is gca(). But how can I get both? Using fig.get_axes() I only got 1 axis. Anybody know?

Re: [Matplotlib-users] how do I get my axis
The reason it wasn't working is that my function foo didn't have the right signature.fmt_xdata takes 1 argument. I have no idea why I didn't see an exception displayed. It's working now that I have def foo(x) pass Mathew John Hunter wrote: On Mon, Oct 13, 2008 at 2:27 PM, Mathew Yeates [EMAIL PROTECTED] wrote: Angus pointed out that I need to do res.fmt_xdata=foo Duh.

Re: [Matplotlib-users] updating a basemap
never mind. Got it working. One annoying thing, though, when the line reaches the edge of the figure, a line is drawn horizontally to the other side.
