ios-charts: Can Selecting A Node Trigger A Labels Text To Change?

I am using ios-charts in swift language. I'm wanting to show more data about each node when they are selected. A marker wouldn't have enough space for all the info I am wanting to display so I am wanting to display it all in a dedicated label on the ViewController itself. Is there any way to do this?

I got the chartValueSelected method working but am not sure how to utilize it for this.

Solution

  • Included ChartViewDelegate

    &

     chtChart.delegate = self

    I have an array called textNotes thats corresponds to each data entry in the array and made a label called infoLabelChart

        func chartValueSelected(_ chartView: ChartViewBase, entry: 
    ChartDataEntry, highlight: Highlight) {
        let pos = NSInteger(entry.x)
        infoLabelChart.text = "\(textNotes[pos])"
    }
