Labels on Mac OS X application : place and title

[satan87]

Hello,

I'm trying to place labels on a chart, with specific title but so far i have no luck.

I use this to display the labels
self.barChartView.xAxis.drawLabelsEnabled = true

and i got this

What i would like is for the label to be just under each bar.
i also would like to rename the labels with the right date.
In my example, not from 0 to 18 but from 1995 to 2016.

Any idea how to do this please ?

thanks,
Nicolas

1. xAxis.labelPosition = XAxisLabelPositionBottom;
2. use valueFormatter to format 0-18 to 1995-2016.
