Puzzled ....

1 Domoticz@Raspberry by means of RFLinkGTW receives the wireless info from 2 rain gauges which are located approx. 4m apart.
Measured numbers are different, but that is possible due to instruments and due to location (and perhaps I have to check the WS7000 rain gauge after 10 years of operation, whether still clean and no wear&tear).
However, in Domoticz' log the information produces a different layout for graphs:
Nexus has thick bars, WS7000 has thin bars.

Any idea of the cause of the difference in layout of the bars?

By the way, (how) can I quickly zoom the graph?
Via the short log setting the time-scale of a graph can be changed between 1 day and 7 days, but deducting from some messages there apparently is a quick way under mouse-control on the graph.
Have tried various approaches, but in vain, and no clear description found, or do I misunderstand?

Ton,
I can only help with the last part:
left click&drag a rectangular over an area to get a zoomed view.
The Reset zoom button will bring you back

@Domosapiens

Thanks for the hint!
I knew it was simple, but one needs to find the info .....

After several Upgrades of Domoticz no longer a difference:
'problem' solved, although don't know how/why .......

Addition 20Nov2016:
After upgrade to v3.5964 the difference is seen again ......
