how to center legend text of LineChartView?

[slzrafael]

I want to center my legend text relative of all graph not only canvas width.

I use this code to do this:

            let legend = graph.legend
            legend.drawInside = false
            legend.wordWrapEnabled = true
            legend.form = .circle
            legend.orientation = .horizontal
            legend.verticalAlignment = .top
            legend.horizontalAlignment = .center

But i have this result:

I guess you need to override some code. The legend in this library is not as smart as you think. I admit there is a lot to improve, but we don't have the man power to do that.
