I use Horizontal Bar and the bars load fine. But don't load all variables name on the xAxis.
Display the variable in the Left of the Bar
This is my result:
This is the code:
var dataEntries: [BarChartDataEntry] = []
for i in 0..<barValues.count {
let dataEntry = BarChartDataEntry(x: Double(i), y: barValues.object(at: i) as! Double)
dataEntries.append(dataEntry)
}
let barChartDataSet = BarChartDataSet(values: dataEntries, label: nil)
let barChartData = BarChartData(dataSet: barChartDataSet)
barChartData.setDrawValues(true)
cell.barChart.legend.enabled = false
cell.barChart.leftAxis.enabled = false
cell.barChart.rightAxis.enabled = false
cell.barChart.chartDescription?.enabled = false
cell.barChart.drawValueAboveBarEnabled = true
cell.barChart.leftAxis.axisMinimum = 0
cell.barChart.isUserInteractionEnabled = false
cell.barChart.noDataText = "NO DATA."
//Left Side
let xAxis = cell.barChart.xAxis
xAxis.enabled = true
xAxis.setLabelCount(barVariables.count, force: true)
xAxis.centerAxisLabelsEnabled = true
xAxis.drawLabelsEnabled = true
xAxis.drawGridLinesEnabled = false
xAxis.axisLineColor = UIColor.black
xAxis.labelPosition = .bottom
xAxis.labelFont = UIFont(name: "Avenir-Medium", size: 12.0)!
//Here I send Array<String> for change values Double to String, but don't load all values.
xAxis.valueFormatter = IndexAxisValueFormatter(values: arrayVariables)
//Current Values
let format = NumberFormatter()
format.numberStyle = NumberFormatter.Style.percent
format.maximumFractionDigits = 1
format.multiplier = 1.0
format.percentSymbol = " %"
let formatter = DefaultValueFormatter(formatter: format)
barChartData.setValueFormatter(formatter)
barChartData.setValueFont(UIFont(name: "Avenir-Light", size: 8.0))
barChartData.setValueTextColor(UIColor.black)
cell.barChart.data = barChartData
return cell

In all cases I need the value on _values, this method is called and return _values on position [index]
On First case need return _values[0] "Where index should be 0", and the index is -1. I forced to return _values[0] when index == -1
Original sentence if is return "" because: index != Int(value) many times.
open func stringForValue(_ value: Double,
axis: AxisBase?) -> String
{
let index = Int(value.rounded())
//--- 1. ---//
if index == -1 {
return _values[0]
}
//--- 2. ---//
//if index < 0 || index >= _valueCount || index != Int(value)
if index < 0 || index >= _valueCount
{
return ""
}
return _values[index]
}
