See only the 75% of my screen, how can I ?

[[Deleted]]

Hi,

I post comments to my screen on the left hand side. They take up about 25% of my screen. The background is black, barchart is green.

How can I always black out the 25% portion of my screen so I can read my comments easily.

Is there a function that reads bars on screen, Bar(left hand side) to bars 25% to the right, then loop thru and change colors of barchart and moving averages to black.

any ideas appreciated, thanks
