Empty pressure graph in sleepyhead this morning

[Islandwoman]

I like the pressure graph because it is easy to see small breaks when I get up during the night. This morning it was nothing but an empty rectangle, no numbers on the left. Pressure graph did appear in Encore. My pressure is a flat 6 so is worthless except to mark when the machine is off during the night but I wonder what happened.

I don't know why it is empty, but the Flow graph is good (better problably) for that purpose too.

Try going to Preferences and the Appearance tab and remove the check mark from "use Pixmap caching"...see if that helps.
It might and it might not but it is all that I know to try
