Issue with coloring grouped datasets in barchart

[yigitserin]

Hi there,

I want to create the same chart as the example image you provided here :
BarChart (grouped DataSets)

I managed to create the same grouping, but when I add color sets, it doesn't work like this.

Here is my attempt:

Code:
`

           var xVals = [String]()
            var datasets = [BarChartDataSet]()

            for i in 0..<json.count{

                var entries = [BarChartDataEntry]()

                for j in 0..<json[i]["Items"].count{

                    if i == 0{
                        xVals.append(json[i]["Items"][j]["X"].string!)
                    }

                    let entry = BarChartDataEntry(value: json[i]["Items"][j]["Value"].double!, xIndex: j)
                    entries.append(entry)

                }

                let dataset = BarChartDataSet(yVals: entries, label: json[i]["Name"].string)
                dataset.setColors(ChartColorTemplates.pastel(), alpha: 100)
                datasets.append(dataset)

            }


            let data = BarChartData(xVals: xVals, dataSets: datasets)

            barChart.data = data`

How do I color by type rather than group?

Solved by using
dataset.setColor(ChartColorTemplates.pastel()[i])
instead of
dataset.setColors(ChartColorTemplates.pastel(), alpha: 100)
