Distinguish LineGraph callback.

[anishparajuli555]

i have a CombinedChartView with multiple linegraphs and a scatter graph.

 let data: CombinedChartData = CombinedChartData(xVals: xAxisdateTimeArr)
 data.lineData = self.setLineData(foreCastData,highlightTime: highlightTime)
 data.scatterData = self.getScatterData(foreCastData,highlightTime: highlightTime)
 chartView.data = data

DataSource for line graph is as below

  func setLineData() ->LineChartData{
          ..........
        var dataSets : [LineChartDataSet] = [LineChartDataSet]()
        dataSets.append(set1)
        dataSets.append(set2)
        dataSets.append(set3)
        let data: LineChartData = LineChartData(xVals: xAxisdateTimeArr, dataSets: dataSets)
        return data
    }

I need to show a popup only when 1st line graph is selected.
But the delegate method is called for each line graph in chartView.
func chartValueSelected(chartView: ChartViewBase, entry: ChartDataEntry, dataSetIndex: Int, highlight: ChartHighlight){}

how do i distinguish the callback of a line graph?

it tells you which entry and dataSetIndex and highlight, I think it's enough

[danielgindi]

It tells you exactly what you need for that, as @liuxuan30 said

i handled delegate using below condition
if let data = chartView.data, data.isKind(of: PieChartData.self) { ... }
