[Matplotlib-users] Nanoseond timestamp on x axis

2013-12-19 Thread Alexandru Popa
I need to plot some large csv files that contain financial data with
timestamps that have nanosecond precision.

Is there a way to make matplotlib show these timestamps as dates with
nanosecond precision?

If not, is there a way to plot my data by sending the timestamps, and then
set a formatter that will show the timestamp based on a custom format of my
choosing?

Note that I'm embedding matplotlib in a wxPython application, and I am not
familiar with the ipython way  of working with matplotlib.

Here are a couple of examples of using custom formats:
http://matplotlib.org/examples/api/date_index_formatter.html
http://matplotlib.org/examples/pylab_examples/date_demo2.html

And here's a link with all of the possible formatting strings:
