I have a realtime timeseries chart which should show a variety of values. To make it mor clear: It should contain values for a solar park. Therefore I have stuff like Voltage, Current, Power (absolute & normalized to 1MW), Temperature and Irradiation.
The irradiation value is a global one so it exists only once. All the other values basically exists for each inverter which is installed on the park, I'm talking about max 20 to 30.
The user will overlay the curves over each other to compare different inverters with each other.
What is the best approach to assign the colors to the curves? I want to be able to distinguish between the devices and additionally between the different values. So lets say I want to compare two inverters both temperature ans power output. The user should be able to clearly see what curve belongs to which inverter and also which is the temperature and which is the power output.
So all in all, if we talk about 20-30 devices, I have around 140-210 different curves (each its own color) which can be combined in any way.
