Y-axis on share chart - is there a way of making it static?

Perhaps this is an option that I have not yet found.

When I scan the share chart on a PC, the y-axis changes depending on the peaks and troughs in the share movement during the time period viewable on the screen. Is there an option to ‘fix’ the y-axis so I can scan the share behaviour without the chart constantly readjusting the share activity?

I hope this makes sense!

Thanks :smiley:
