Multiple entries of the same item in legend

[yigitserin]

Hey there,

Trying to implement a bar chart into my app. It works but there is an issue with legend. As you can see in the image, color boxes are shown for all items:

However expected behaviour is as shown bellow:

Why is that happening? My code is bellow:

`

            let barChart = BarChartView(frame: CGRectMake(0, 0, parent.frame.width, 400))
            let json = JSON(data: jsonString)

            var dataSets = [BarChartDataSet]()
            var xVals = [String]()
            for i in 0..<json.count{
                if let items = json[i]["Items"].array{

                    var yVals = [BarChartDataEntry]()

                    for j in 0..<items.count{

                        if i == 0{
                            xVals.append(items[j]["X"].string!)
                        }
                        yVals.append(BarChartDataEntry(value: items[j]["Value"].double!, xIndex: j))
                    }

                    let dataSet = BarChartDataSet(yVals: yVals, label: json[i]["Name"].string!)
                    dataSet.setColors(ChartColorTemplates.pastel(), alpha: 100)
                    dataSets.append(dataSet)
                }
            }
            let data = BarChartData(xVals: xVals, dataSets: dataSets)

            barChart.data = data

And this is the json data if it is required:

I think because you are using grouped bars rather than single bar. Check out ChartsDemo
