[ephyviewer] synchronizing horizontal size and scale of viewers

[Peter N. Steinmetz]

I am using ephyviewer to construct a window with multiple trace and spike viewers. 

Presently the scale of the spike viewer occupies a different width in the window from the trace viewers. See attached. 

Is there an existing feature to change this and make the horizontal extent of the x-axes the same in all views?

A bit of noodling around in the pyqtgraph source code resulted in the following, which works:

if plots is a list of all the plot items in the ViewBoxes to be aligned

maxWidth = max(plt.axes['left']['item'].width() for plt in plots)
for plt in plots:
   plt.axes['left']['item'].setWidth(maxWidth)

Hi Peter.
Yes. I know.
It is due to the ylabel. Maybe there is a possible fix in pyqtgraph.

Oh good idea.
Could you make a PR ?

Perhaps after my other ones on python-neo get reviewed.
