bug: physmon prints many lines with variable

[AJPfleger]

Issue

The logs of the physmon contain many line filled with variable (around 10%).
@paulgessinger suggested, that it might be due to a bug in the plotter.

Severity

Has probably no effect on the monitoring itself, but clutters the logs and makes them harder to read.

Details

Here is a portion of the log:

[paulgessinger]

It's actually in histcmp, sorry.
