plotting not showing for certain channels

I searched to no avail.

problem: I see some channels plot, like speed, RPM but not for Shift Solenoid Pressures (and others) as shown in the screenshot below.

The same channel in a gauge works, but I need graphs to compare against other pressures.

Are some channels not able to be plotted/graphed or do I need to enable something for the channel to make it plot.

Thanks for help...

I had to populate the 'Max Limits' with a value in the channel
