Multiple domoticz_graphs of the same period

[wez3]

A bug exists when using multiple domoticz graphs of the same period. For example these two graph of the same type domoticz_smart_charts use the same period "day":
[[domoticz_smart_charts]]
[[[1]]]
Wekelijks energy verbruik = 155, day, energy
[[[2]]]
Wekelijks gas verbruik = 156, day, gas

Due to the global variables that are used within domoticz.js multiple graphs, of the same type, within the same period are not possible.

During the development we decided to not fix this bug as it requires a big rewrite of domoticz.js.

We might fix this issue in the future. Not in the roadmap yet.
