[Matplotlib-users] get_*gridlines alwys returns the same things?

2010-05-04 Thread Nico Schlömer
This is weird: When plotting something very simple, e.g., t = arange( 0.0, 2.0, 0.01 ) s = sin( 2*pi*t ) plot( t, s, ":" ) I thought I can check weather the grid is on or off by gca().get_xgridlines() -- but this *always* returns with *always* the same lines Line

Hi Jeff, Thanks very much for your response. As you noted, I do not understand the Basemap global sinusoidal coordinate system. Does this statement not set up a global sinusoidal cartesian coordinate system centered at (lon = 0.0, lat = 0.0)? m = Basemap(projection='sinu', resolution=None, lon_

Hello, I am trying to generate a 3d-plot I have two functions that depend on two free parameters, T_g = (5./512.) * Light_c**5 * a**4 / (Grav_G**3 * m**3) T_d = 3.e4 * sqrt(a**3/ (Grav_G * m**2.)) These are given in units of time, so that I would like axis y to be "time", running between 1.0

Eric, Thanks a lot for the pointers. Sorry for the double posting. I tried fill_between, which works better than bar graph. But I need to change the data set to be able to get the filling into a nicely-formed rectangle, and the performance is still not very good. As the below example shows: imp
