Adjust Scaling of Correlated Instrument Lines

[oldporkchops]

At the moment, if a correlated instrument moves out of scale, the line disappears at the top or bottom of the screen.

Could you please enhance the scaling of correlated instruments such that the top and bottom of the heatmap area is the 0-100% scale of the correlated instrument. In other words, use the vertical axis to scale the correlated instrument using percentage.

Thanks.
