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

Can you post an simple selfcontained 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) On Thu, Aug 18, 2011 at 1:10 PM, R.

JaeJoon, thanks for your reply. There is a combination of effects that make my contour labels placed in unfortunate positions. Here is a selfcontained 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.

Hi, I think this is partly because the current clabel implementation of matpltolib does not correctly account the dpi setting. I opened a pull request I think fix this problem. Please try that fix if you can. https://github.com/matplotlib/matplotlib/pull/453 Otherwise, I think you can workaround this by using the default dpi (72 or similar).
