Uncaught TypeError: jQuery.plot is not a function

I have Google Analyticator 6.4.8 installed on 2 wp websites.

Both are not showing the graph in Dashboard -> Google Analytics Summary

No matter 30 days, 60 days, Yesterday. None of them show the graph.

Both are showing this error:
Uncaught TypeError: jQuery.plot is not a function

Does this have to do with it? And how can it be fixed?
