Changing color of the bar graph

[millerrob1000]

Looked through the demo and didn't see a way to change the color of the bar graph part way though and then change it back. Basically I want to have the graph blue and then change to orange when a flag is triggered and then change back to blue.

Attached is an example of what I'm looking for.

 func setDataCount(_ count: Int, range: Double)
   {
       // MARK: BarChartDataEntry
       var yVals = [BarChartDataEntry]()
       for i in 0..<count
       {
           yVals.append(BarChartDataEntry(x: Double(i), y: Double(values[i])))
       }
       
       // MARK: BarChartDataSet
       var set1 = BarChartDataSet()
       if chartView.data == nil
