Dynamic zoom y-axis

[dflatow]

Is your feature request related to a problem?

There are times where a labeler may want to “zoom” into a particular vertical range of a time series. Currently my understanding is that you can set the y range via:

#168 (comment)

On: don't scale y axis at all, always fit for all the values on channel

Off: scale to fit currently displayed data

Can be changed globally for TimeSeries and locally on Channel

Describe the solution you'd like

Ability to do one or more of the following:

• set the y-min and y-max via direct numerical input.
• slider connected with a numerical output ( so that the user can see which value is actually selected with the slider)
• selectable magnification levels (e.g. 1x, 2x, 3x, etc.) via something like a radial button.

This is exactly what I need too for labeling EMG in multiple channels at the same time. When everything is dynamic, it is super difficult to judge relative amplitude differences @makseq.

I also started a thread on slack about this.
