How to use a second Y axes? It is added in version 9.1 but I could not select the data.
Let me share my pain.
not sure what do you want me to share. Just bind two data series to a LineChart and try to associate one of them with a secondary Y axes. I could not.
but the question is how to associate one of the series (you have 3 on you screenshot) with the secondary Y axes? Try to pickup one.
And it's not really 'Multi Y', but just two.
