Adjustable scale (add/reduce) [in conjunction w/dragable lines]
Similar to the TK6 feature of adjustable scale to increase and/or decrease the Y-axis scale. (and in conjunction with having the ability to reposition the lines to make the view clearer and/or be able to see the price bar trend)
The scale automatically adjusts if you move a line/data series or remove it through the legend. You do not need to manually add or reduce scale to see all of the graph lines.

Many many times the graph is off screen for Earnings per Share and Pre-Tax Profit. Even moving the lines can be difficult. It would be good to scroll the Y axis to at least see what is off screen.
Zooming scale would also be wonderful.
