How Many Charts to Keep Open

Every open chart costs a share of the screen, a share of your attention and a block of bars in memory, and the number to keep open is the number one person can actually watch, with the rest tiled out of the way or saved in a profile. This paper shows you the question in five lines; the idea as a lifeguard's chair and the stretch of water one guard can cover; Window, Tile with four charts on one screen; the Max bars in chart setting and what each open chart holds; and profiles on your platform, one set of charts per job.

Open charts, in five lines

How many charts to keep open is a question about cost. Every open chart takes a share of the screen, a share of your attention, and a block of bars held in memory. Window, Tile, arranges them two, four or six side by side, or one at a time in tabs. The number that fits is the number you can actually look at, which on one screen is usually two to four. The rest are closed, or kept in a second profile that opens with one click. Tools, Options, Charts, has the Max bars in chart setting that caps what each one holds. The platform will open fifty; there is one pair of eyes in the room.

A lifeguard's chair

Picture a lifeguard's chair and the stretch of water one guard can watch: four swimmers inside the two dashed lines, and two beyond them, out of view. A beach with twelve swimmers does not need one guard looking harder; it needs the stretch cut to what one guard covers, and the other swimmers in another guard's stretch or out of the water. Open charts are the swimmers. Their number is set by what one pair of eyes can watch, not by how many the platform can open, and the ones outside the stretch are not watched at all, whatever the screen says.
