Invalid JSON exported from graph

No, it is still not there where I would like to have that. I’m still not having my pure digital graph with sharp edges. This one describes the number of (conference) rooms seen active. Of course it went from 0 to 1 to 2 to 1 to 0 again. Values in the graph are: 0, 0.05, 1, 1.03, 2, 1.98, 1, 0 and so on.

Is that all what I can achieve?
