Skipping error in for-loop

Question

I am doing a for loop for generating 180 graphs for my 6000 X 180 matrix (1 graph per column), some of the data don\'t fit my criteria and i get the error:

Answer 1

Instead of catching the error, wouldn't it be possible to test in or before the myplotfunction() function first if the error will occur (i.e. if the breaks are unique) and only plot it for those cases where it won't appear?!
