Re: [Matplotlib-users] pylab (drag_pan )
To create a cursor that only pans horizontally, I'm thinking of writing a special version of drag_pan in backend_bases.py It would call drag_pan in axes.py with the key argument set to 'x' Any advice, suggestions? backend_bases.py : def my_drag_pan(self, event): 'the drag callback in pan/zoom mode' for a, ind in self._xypress: a.drag_pan(self._button_pressed, 'x', event.x, event.y) self.dynamic_update() # # In axes, up/down motion is prevented when the 'x' key is down # axes.py def drag_pan(self, button, key, x, y): ... elif key=='x': dy = 0 ...

Thank you. Now it is fixed. BTW, do you know how to constrain the panning function to left/right programmatically? I'm try to make a logic analyzer. I don't know offhand, but I don't think that capability is in place. I find holding down a key while panning to be a bit awkward, so I am also interested in alternatives. Finally, is this the best place to post my questions? (I suspect not...) Yes, matplotlib-users is the right place. I assume you intended to reply-to-all on that last one, so intended it to go to the list. Apparently the settings on this list are unusual in that one must explicitly reply-to-all; it is not automatic that one's reply goes to the list.

[Matplotlib-users] Interactive navigation toolbar documentation recommendation
I just realized that by clicking once on the pan button, the cursor goes into pan, and clicking again, it goes back to the arrow. Same for some of the other buttons. I realized this by looking at the code. I would recommend that the documentation at the link shown below say something about this. http://matplotlib.sourceforge.net/users/navigation_toolbar.html Marc Desmarais Long Beach, CA, 90814 -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

what's a patch for?

[Matplotlib-users] can't picker once pan or zoom chosen
I created a simple scatter plot and a service routine to print out the
coordinates of the points I pick with the cursor (based on the demo). It works
until I select the pan or zoom cursor. After I zoom or pan, I can no longer
get back to the normal cursor which allows me to pick a circle. Even clicking
home doesn't help.
The code is shown below
from matplotlib import figure,pyplot
from numpy import linspace,sin,take
fig=pyplot.figure()
ax1=fig.add_subplot(1,1,1) # (numRows, numCols, plotNum)
t=linspace(0,10,100)
y1=sin(5*t)
y2=y1+sin(10*t)
line1=ax1.scatter(y1,y2,picker=True)
def onpick1(event):
ind = event.ind
print 'onpick1 scatter:', ind, take(y1, ind), take(y2, ind)
fig.canvas.mpl_connect('pick_event', onpick1)
pyplot.show()
this is based on the demo at
http://matplotlib.sourceforge.net/examples/event_handling/pick_event_demo.html?highlight=scatter

the following does not work (the earth does not appear):

Re: [Matplotlib-users] embeding basemap in Tk
I think I needed to create an axes. This seems to have solved my problem.
a = f.add_subplot(111)
map = Basemap(projection='ortho',
lat_0=34.0,
lon_0=-117.3,
resolution='l',
area_thresh=1000,
