Matplotlib adds %f to end of the xtick date label in Python3

[alaudet]

Seems like converting bytes to string for python 3 matplotlib add %f to the end of the time.

20:00:00.%f instead of just 20:00:00

There is an issue with dates in matplotlib that is addressed in 1.5.

Thanks to user tacaswell who provided a workaround.

I will implement his suggested workaround.

Re-opening. While this is not a very serious issue I have not yet implemented any fix (even though it is only for very small log files with a few readings)

It only seems to be doing this when there are a handful of readings. It happens when the scope of the x axis has very few dates and wants to add microseconds to the date and put %f instead.
I am going to close this issue as it has so little impact and apparently will be fixed in a later version of matplotlib.
