foxplot's Issues

Deterministic color mapping

It is a minor inconvenience when I plot the same fields in two different log files (e.g. when I run the same experiment with different conditions) and get different color mappings. The color mapping is random now and different every time.

It should be very easy to get a consistent mapping using ordered sets (As Python sets are not ordered by default):

foxplot/foxplot/generate_html.py

Line 89 in 2ffdb2d

left_labels = set(left_axis.keys())

Although the inconvenience is minor, the fix is very easy as well. Do you think it's a desirable property? If so, I'll create a PR.

Error in particular JSON file

The JSON file in test2.zip yields the following error:
