How can we format the LABEL used for values?

[dhomes]

I have a line chart for which I'm using a IValueFormatter for the labels' text, I can also customize the labels' font and textcolor

But is there any way to access the UILabel itself for customization? I want to add a custom background color to it and also access the label's layer property (round corner, bordercolor, etc)

use valueFormatter and ask on stack overflow next time.
We don't have a UILabel. It's rendered by CoreGraphics so you could use CG's APIs to draw background rect.
