Is it possible to configure the highlight of a bar / column series to make it more obvious that the series is clickable? I tried changing the border of the series's highlight property but from the documentation, it seems border is only available for "donut", "bubble", "pie", "candlestick", or "ohlc" charts. I just need a way to make the series data pop out more when user hovers over it so they know it's "clickable". Even if I can change the mouse cursor to pointer would be nice.
