Remove Highlight from bar graph

[AH24]

I currently have a storyboard where the first page contains a bar graph, when the user selects a bar I push to the next page. When I go back from that page the selected bar is still highlighted and I have to click it again to remove that highlight.

I was trying to remove the highlight in the function:
-(void)chartValueSelected:(ChartViewBase *)chartView entry:(ChartDataEntry *)entry highlight:(ChartHighlight *)highlight;
but I am not having any luck.

I am using Objective C. How do I go about doing this? I don't want to disable the highlighting all together just remove that highlight from the selected bar.

chartValueSelected is delegate method, calling it by yourself is not supposed to work.
You can remove the highlight by passing nil or empty highlight objects in

open func highlightValue(_ highlight: Highlight?, callDelegate: Bool)

Just take a look at the implementation.

How do I call that using objective c?
