Answer 1

The questions asks how to set a limit to the view which none of the responses to this point answers. For others who come across this the view of the plot can be limited to a section of the axis like this:

p1.plotItem.vb.setLimits(xMin=a, xMax=b, yMin=c, yMax=d)

Answer 2

As the error message indicates, you have not supplied the correct number of arguments to setXRange(). The correct line should look like:

p1.setXRange(5, 20, padding=0)

Michael.

The easiest way would be to simply specify your ranges as elements of a list. Replace the p1.setXRange with something like this:

p1.setRange(xRange=[5,20])

And that's it!
