Using the mouse to click and drag on a logarithmic y axis triggers a zooming behaviour as if the user zoomed in on a linear axis. 

How to reproduce:
Take a plot that ranges from 1e-20 to 100, for example. Click around the middle of the axis and drag the mouse up to about 3/4.

Expected result:
Limit the y axis to the approximate range 1e-10 to 1e-4

Actual result:
The y axis limits are around 50 and 75.


P.S. Is there a way to configure the history plot in a way that values of 0.00 are ignored rather than showing up as 1e-20?
