What problem are you trying to solve?

Some charts needs to display data of 2 different scales and units. Therefor a support for a left and right y-axis would be helpful.

Describe the solution you'd like

Turning y-axis config to accept a map or array with a name as key. Using name can be used to assign a series to. As alternative I used in a POC a hardcodedy2 property next to y.
