change log line color, is it possible (highcharts)

[Stratos]

Hello,
running Domoticz since some weeks mainly to watch several temperatures and humidity in the house.
Since the beginning i was confused about the log line colors ( yellow:temperature, green:humidity),
i would prefer to have red:temperature , blue:humidity
Have searched for a while to find a way to change the line color but didnt found a hint.
Is there a way to do this and if not would it be nice to implement this?
Thanks

Hello again,
is there no hint?
At least a "read the forum" or "not possible" would move me forward .
Also a "noone needs this" or "just try to find this alone" is good.
On the highcharts website i have seen an example to change the line color.
ATM i'm not able to find the right place to implement this in the code.

Thanks
