I have a chart with multiple data series and multiple axis similar to http://demos.kendoui.com/dataviz/bar-charts/multiple-axes.html
I want a way to give the user a clue which axis is related to which data series, so I've tried applying colors that visually tie them together. However this approach doesn't work too well with themes (try setting the demo to Black - you can hardly see one of the axes).

So what I'm thinking now is to visually highlight the axis when the user hovers over the data series and/or legend. Similar to the way that hovering over the legend highlights the associated data series. 

Could anyone give me a clue how to do this highlighting? or even any alternative ideas

Hi Alex,

I am afraid highlighting the axes is not supported in Kendo UI Chart at this point. If you wish you could submit this idea as a feature request at our UserVoice portal - this way the community would be able to evaluate it and if the suggestions gains popularity we will consider its implementation for future releases.

Meanwhile as an alternative idea I can suggest you changing axes and series colors (for example when use the Black theme you could set some light colors).
