I have created a python program that uses matplotlib to plot data and it had been working fine until today, an error occured. The program uses AutoDateLocator and ConciseDateFormatter. As you can see in the last line of the error log below, the received error is:
> IndexError: too many indices for array: array is 1-dimensional, but 2 were indexed
Since it would be really difficult to post more details about my program functionality as well as the data used, I was wondering if there is an obvious solution to the above-mentioned problem, or if you could guide me to where I should look for the problem.
