Jae-Joon, thanks for your reply.
There is a combination of effects that make my contour labels placed in unfortunate positions. Here is a self-contained example (somewhat different from issue I originally explained, but illustrates the fact clabels are not where I'd like them to be)
import numpy as np
import matplotlib as mpl
ff = 10
params = {
'text.usetex': True,
'axes.labelsize': ff,
'axes.fontsize': ff,
'legend.fontsize' : ff,
'xtick.labelsize' : ff,
'ytick.labelsize' : ff,
'figure.dpi': 150,
'figure.figsize' : [5,2],
}
mpl.rcParams.update(params)
import matplotlib.pyplot as plt
import matplotlib.gridspec as gridspec
gs = gridspec.GridSpec(1,2)
ax = plt.subplot(gs[0])
xi = np.linspace(0,0.4,100)
yi = np.linspace(0,0.4,100)
xx,yy = np.meshgrid(xi,yi)
zi = np.sin(5*xx*yy)
v = np.arange(0.0, 0.5, 0.1)
cplot = ax.contour(xi, yi, zi, v, linewidths=0.5, colors='k')
ax.clabel(cplot, v,
fontsize = 8,
inline=True,
fmt = "%0.2f",
)
ax.axis([np.min(xi),np.max(xi),np.min(yi),np.max(yi)])
plt.show()
The end result is that contour labels are placed almost outside of the grid, with most of the area in the center being blank. I am pretty sure it has to do with the way rcParams are set, but I have no idea why. Params I do need to set are text.usetex, figure.dpi, and figure.figsize. I am using matplotlib 1.0.1.
Thanks for your help,

Subject: Re: [Matplotlib-users] contour's clabels overlap each other in an ImageGrid
Can you post an simple self-contained script that reproduces your problem?
I just tried something similar but could not reproduces your problem.
Here is what I did,
Also, what version of matplotlb are you using?
Regards,
-JJ
import matplotlib.pyplot as plt
import numpy as np
from mpl_toolkits.axes_grid1 import ImageGrid
fig = plt.figure(1)
arr = np.arange(100).reshape((10, 10))
grid = ImageGrid(fig, 111, (2, 2))
cntr0 = grid[0].contour(arr)
cntr1 = grid[1].contour(arr)
cntr2 = grid[2].contour(arr)
cntr3 = grid[3].contour(arr)
plt.clabel(cntr0, manual=True)
plt.clabel(cntr1, manual=True)
plt.clabel(cntr2, manual=True)
plt.clabel(cntr3, manual=True)

Hey guys,
I was hoping someone could provide a hint for how I should go about correcting this. As you can see, locations for the inline labels for
contours in this image are unfortunately chosen, and they overlap with one another. If I set manual to 'True' then I get this weird behavior
where I can only choose labels in the top left grid and nothing is shownin any of the other grids.
I am using a 2x2 Image Grid (I get the same problem when using gridspec instead of image grid), and loadingcontour data (2x2 array) from a file.
Thanks for your help,
Ron
