Simple Radar Chart causing hang / cpu 99%

[royherma]

Trying to create and load a simple RadarChartView, however when assigning data to it, it causes the app to freeze / cpu goes to 99%.

@IBOutlet var radarChart : RadarChartView!

let entries = [
                ChartDataEntry(value: 0.8, xIndex: 0),
                ChartDataEntry(value: 1.8, xIndex: 1),
                ChartDataEntry(value: 2.8, xIndex: 2),
                ChartDataEntry(value: 3.8, xIndex: 3),
                ChartDataEntry(value: 4.8, xIndex: 4),
                ChartDataEntry(value: 5.8, xIndex: 5)
                ]
            
let dataSet : RadarChartDataSet = RadarChartDataSet(yVals: entries, label: nil)
dataSet.drawFilledEnabled = true
dataSet.drawValuesEnabled = false
let data = RadarChartData(xVals: ["1","2","3","4","5","6"], dataSets: [dataSet])
            
self.radarChart.data = data

When no data is assigned, the chart loads and display the valid "no data text", however as mentioned assigning data to it (i've tried multiple forms) causes the problem.

Would love some help, thanks!

try that

   let entries = [
        RadarChartDataEntry(value: 0.8),
        RadarChartDataEntry(value: 1.8),
        RadarChartDataEntry(value: 2.8),
        RadarChartDataEntry(value: 3.8),
        RadarChartDataEntry(value: 4.8),
        RadarChartDataEntry(value: 5.8)
   ]
    
    let data = RadarChartData()
    let dataSet = RadarChartDataSet(values: entries, label: nil)
    dataSet.drawFilledEnabled = true
    dataSet.drawValuesEnabled = false
    
    data.addDataSet(dataSet)
    
    self.radarChart.data = data

Don't have RadarChartDataEntry, so did this:

let entries = [
                ChartDataEntry(value: 0.8, xIndex: 0),
                ChartDataEntry(value: 1.8, xIndex: 1),
                ChartDataEntry(value: 2.8, xIndex: 2),
                ChartDataEntry(value: 3.8, xIndex: 3),
                ChartDataEntry(value: 4.8, xIndex: 4),
                ChartDataEntry(value: 5.8, xIndex: 5)
            ]
            
            
            let data = RadarChartData()
            let dataSet = RadarChartDataSet(yVals: entries, label: nil)
            
            data.addDataSet(dataSet)
            
            self.radarChart.data = data

Got this (it's the cell with the corresponding values):

You have a version that is obsolete
update to chart 3.0

[royherma]

wanted to update but can't due to conflicts with swift 3.0 and older versions in my project @thierryH91200

I believe it should still work on older versions...

[pmairoldi]

Interesting. What version are you using 2.3? I can try it out.

[royherma]

@petester42 using 2.3.1

[royherma]

any luck @petester42 ?

[pmairoldi]

Im just trying it now. And I don't see this problem. Im using an iPhone 6 to test and its never goes over 2. Maybe you're doing too much stuff on the main thread in your app?

[pmairoldi]

I suggest you update to 3.0 soon since swift 2.3 is deprecated and will be removed in Xcode 8.3
