FR - GKBar - add value labels

[liaojinxing]

Great job!
I think if the value of the bar shown in the left side, it would be more intuitive, just like GKLineGraph.

Sure. I will add a functionality soon.

Great job on the graphkit. Any chance this has been implemented yet?

Thank you

I am really sorry but I have not had a chance to do it so far. Hopefully by the end of this year.
