Hi, I've managed to take the contents of my CSV file and display it with matplotlib. I'm having some issues with the way my X-axis is being displayed.
For the X-axis, I pass in a list that filled with datetime objects, an example of one element on the list: datetime.datetime(2007, 12, 17, 20, 28, 15), Issues (please see the attached cpu.png: - for some reason a TZ has been inserted - graphs have white space buffers on either side of the X-axix - points on X-axis are separated by the hour, instead of values in datetime object I have tried many variations of plotdate, etc. If someone could please point me in the right direction.
