Radar charts custom labels

[chipp]

Custom radar chart labels are broken.
I added this code to ChartsDemo-OSX/ChartsDemo-OSX/Demos/RadarDemoViewController.swift:

data.setLabels("a", "b", "c", "d", "e", "f", "g", "h", "k")

but RadarChartView ignores these labels.

I think problem is in this line: XAxisRendererRadarChart.swift#L57

XAxisRendererRadarChart ignores RadarChartData.labels property.

I think you should use valueFormatter to do that, as you already see where it formats.. Labels are just labels sometimes.

[chipp]

/// Sets labels that should be drawn around the RadarChart at the end of each web line.
    open var labels: [String]

ok...

@chipp lol. But the code tells everthing :(
@danielgindi looks like labels are not used anymore?

any news here?

@tlimp this is my production solution:

chartView.xAxis.valueFormatter = RadarChartXValueFormatter(withLabels: labels)

class RadarChartXValueFormatter: NSObject, IAxisValueFormatter {

  init(withLabels labels: String...) {
    self.labels = labels
    super.init()
  }

  init(withLabels labels: [String]) {
    self.labels = labels
    super.init()
  }

  var labels: [String]

  func stringForValue(_ value: Double, axis: AxisBase?) -> String {
    let index = Int(value)
    return labels.indices ~= index ? labels[index] : ""
  }

}

thanks, for the help. at least it renders the labels. but it also renders a large white space left and right padding/margin, so the chart gets illegible. margin/padding are much larger than needed by the labels
in a previous version (2.2.3 I guess) it worked as expected, making the chart as large as possible so the labels where still readable.

same issue here, have labels with roughly 10 characters and it's shrinking the chart a lot sometimes the chart is not readable at all :(

The issue with white spaces is still present! Does anyone know how to remove those?
