Bug in History-Chart

[delphinis]

Describe the bug
There is an issue in the History chart. See also at: https://forum.iobroker.net/topic/79688/bug-in-history-adapter-diagramm
The incrementation display (line and its underlying area) is wrongly made (Blue). It should be like the red line.
If you get a new measure value, then this has an effect in the "future", not in the past. But it is important to know, that this error is only well visible, if you have just a few values, with a certain delay between. See below.

To Reproduce
Steps to reproduce the behavior:

1. Measure some values which occurs just sporadic like from temperature sensors of from a power measuring on a fridge.
2. Look at the point with the new measured value. From this point, this value is valid until the next time a new measure is done - not to the past. If you look at the Grafic with 5 measure points, you can see the measuring point 1.5W. From this time, the grafic line should go to the right, not up to 18Watts!
   Expected behavior
   Look at the point with the new measured value. From this point, this value is valid until the next time a new measure is done - not to the past. If you look at the Grafic with 5 measure points, you can see the measuring point 1.5W. From this time, the grafic line should go to the right (the next measure point), not up to 18Watts -> it's still 1.5W.

Screenshots & Logfiles

Versions:
Adapter 3.0.1

Additional context
Eventually this issue is in the Admin Adapter, when you just deliver this graph from there...?
