Issues with Dynalog and trajectory log

first of all: I’m not a physicist, I’m a computer scientist.
Now I have a quick question about the dynalog and the trajectorylog. When I use the …run_demo() method, I get a graphic output. What do I see there?

The first pic is labeled “Actual Fluence”. What do I see there? I mean, what is the label of the axes?

Actually, that’s my problem with every single graphic. I miss labels, I don’t get what I’m supposed to see.

Can anyone explain to me what the labels of the axes in this 6 pics are?
