Displaying float values in bar chart label.

[gabhisekdev]

Hi,

I have a bar chart in my project in XCode 8.3 and SWIFT 3. I want to display float values upto a max of 2 decimal places and a minimum of 0 decimal places depending upon the value of data passed.

My current code:

To pass data:

var dataEntries: [BarChartDataEntry] = []
        for i in 0...weekData.count-1 {
            print("\(i) day data \(Double(weekData[i]))") //e.g. weekData = [0.0,12.03,3.0]
            var dataEntry = BarChartDataEntry(x: Double(i), y: Double(weekData[i]))
            dataEntries.append(dataEntry)
        }
        let chartDataSet = BarChartDataSet(values: dataEntries, label: nil)
let chartData = BarChartData(dataSet: chartDataSet)

Problem:
My values are not displayed in float rather are rounded off to nearest whole number.

So is there any way to achieve this?
