Dragable chart (up and down) pretty please!

Hi there,
Ok so we can scroll charts left and right but if I want to move a chart upwards/downwards without changing scale I can’t. I want to be able to left click-drag the chart any direction I wish without any scale changes please.

Quite often I want plot lines and drawings above the current high but I simply can’t without squishing the volatility out of the chart which is pretty pointless if you are plotting with volatility in mind.

I could go on but you get the idea (I hope)
