no plots in analysis example

[Nimda1482]

Hello. when i use analysis.py in example it gives me no plots in output. I have demo.asc and demo.edf files. what is the problem?
i think it's because of the demo.txt file. what should be in that file? thank you.

The txt file is a behaviour log as one would get from an experiment that was scripted using PyGaze. The analysis example assumes it is there, and won't do anything if it isn't.
