Hi, when I use the function "contour" sometimes I get a broken contour line. This should be continuous. Probably this is a bug. Does anyone know anything about this issue?
Regards,
Ozgur
Could you please post an image of what you are seeing, and possibly the data used to create this? Also, which version of mpl are you using?

Please forget it. For now the real problem is: I am plotting by using "contour" and I get the data values by using get_paths. But it does not include some part of the contour. A screenshot is attached. The colored lines are those returned by get_paths. But the black line is not included. I guess this is a bug?
contour = plt.contour(xi,yi,zi,numberoflevels,linewidths=1,colors='k')
lev = contour.levels
col = contour.collections
polygons =
for i in range(len(lev)):
polygons.append (col[i].get_paths()[0].vertices)
... other code to plot the colored points...

You are assuming that there are the same number of contours as levels. In the general case, this can never be assumed. Why not just simply loop over the collections(or, even better, use a list comprehension)?

lev = contour.levels

I guess that is the problem. Thanks for the idea.
