UEA spurious coincident events

[dizcza]

Unitary events are displayed outside of the region where the analytical significance crosses the p-value threshold. The issue persists in the old UEA plots, so it's not a regression bug introduced by the recent changes in #32.

The figure is a zoomed-in part of the UEA tutorial.

Updated the plot.

Even if the events are not spurious, they look as such. What should we do about it?

BTW, the bottom axis 5 is not shifted by win_size / 2 in the X direction as in axis 4, for example.

It's hard to tell if this is spurious in this plot without a time axis and the value for the UE window (e.g., 100ms).

In general, red "UE spikes" in the lower plot may occur up to half the window size to the left or right of each point crossing the significance threshold in the upper plot. This is because each point on the upper plot is calculated from a window of that size centered on that point. Within that window, it is impossible to tell (in simplified worlds) which coincident spike are "excess" and which are "chance".
