Balloon Marker: making it work in line chart inside combined view

[egmonterrubio]

Hello; I'm learning to use Charts, it's an amazing tool, thanks for sharing it.

I created a CombinedChart with bars and lines, and it's working fine, then I added the BallonMarker and it works with the bar chart but it doesn't consider the line chart, I added the option to select if the user wants bar and line, just bar or just line charts, and with the option of just bars selected it still works, but I can't make it work with the line chart, is there something that need to be changed in the Balloon Marker code?

This is the code I use to create it:

let marker:BalloonMarker = BalloonMarker(color: UIColor.red, font: UIFont(name: "Helvetica", size: 12)!, textColor: UIColor.white, insets: UIEdgeInsets(top: 7.0, left: 7.0, bottom: 7.0, right: 7.0))
        marker.minimumSize = CGSize(width: 75.0, height: 35.0)
        combinedChartView.marker = marker

Also, one more thing, is it possible to make the BallonMarker change position if there is not enough space to be shown, like this case?

Thanks!!

Balloon marker is just a demo marker. You can create your own marker class and do whatever you like to display and where.
