ios-charts horizontal bar charts issues - ios

Question

I experience a number of issues with the horizontal bar chart since I updated to the last version of ios-chart (3.0.0).
First thing is that I had labels for the x axis on the charts. With the new version of ios-charts I had to write my own formatter nevertheless only every second label get displayed now. The second problem is that the bar does not reach the value indicated on the y-axis. What I mean by that is that if I give the bar a value of 4 the height of the bar is actually not long enough to reach the 4.0 label on the y-axis. Those 2 issues are illustrated in this picture.
picture of the problems
Here is my code for the value formatter:
#objc(BarChartFormatter)
public class BarChartFormatter: NSObject, IAxisValueFormatter{
var labelArray : [String] = ["text1", "text2", "text3", "text4", "text5", "text6", "text7", "text8", "text9", "text10"]
public func stringForValue(_ value: Double, axis: AxisBase?) -> String {
return labelArray[Int(value)]
}
}
And here is the code for the bar chart
horizontalBarChartView.noDataText = "You need to provide data for the chart."
horizontalBarChartView.isUserInteractionEnabled = false
horizontalBarChartView.drawGridBackgroundEnabled = false
horizontalBarChartView.drawValueAboveBarEnabled = false
horizontalBarChartView.legend.enabled = false
horizontalBarChartView.drawBarShadowEnabled = false
horizontalBarChartView.chartDescription?.text = ""
horizontalBarChartView.setExtraOffsets(left: 0, top: 0, right: 0, bottom: 0)
// Right y axis
let barRightAxis = horizontalBarChartView.leftAxis
barRightAxis.drawGridLinesEnabled = false
barRightAxis.enabled = false
let formato:BarChartFormatter = BarChartFormatter()
let xaxis:XAxis = XAxis()
// Left y axis
let barLeftAxis = horizontalBarChartView.rightAxis
let count = 5
barLeftAxis.setLabelCount(count, force: true)
barLeftAxis.drawGridLinesEnabled = false
barLeftAxis.axisLineWidth = 2
barLeftAxis.axisLineColor = UIColor.white
barLeftAxis.labelTextColor = UIColor.white
barLeftAxis.axisMinimum = 0.0
barLeftAxis.axisMaximum = 4.0
barLeftAxis.granularityEnabled = true
barLeftAxis.granularity = 1.0
barLeftAxis.decimals = 0
// x axis
let barXaXis = horizontalBarChartView.xAxis
barXaXis.drawGridLinesEnabled = false
barXaXis.axisLineColor = UIColor.white
barXaXis.axisLineWidth = 2
barXaXis.labelTextColor = UIColor.white
barXaXis.labelPosition = .bottomInside
barXaXis.granularityEnabled = true
barXaXis.granularity = 1.0
barXaXis.decimals = 0
var dataEntries: [BarChartDataEntry] = []
var colors: [UIColor] = []
let theScoreVec = [1.0, 2.0, 3.0, 4.0, 3.0, 0.0, 2.0, 0.0, 1.0, 4.0]
for i in 0..<10 {
let theScore = theScoreVec[i]
if (theScore == 0.0){
colors.append(UIColor.clear)
let dataEntry = BarChartDataEntry(x: Double(i), y : Double(4.0))
dataEntries.append(dataEntry)
} else {
colors.append(UIColor.red)
let dataEntry = BarChartDataEntry(x: Double(i), y: Double(theScore))
dataEntries.append(dataEntry)
}
}
xaxis.valueFormatter = formato
barXaXis.valueFormatter = xaxis.valueFormatter
for i in 0..<10{
formato.stringForValue(Double(i), axis: xaxis)
}
xaxis.valueFormatter = formato
barXaXis.valueFormatter = xaxis.valueFormatter
let chartDataSet = BarChartDataSet(values: dataEntries, label: "Completion")
chartDataSet.colors = colors
let chartData = BarChartData(dataSet: chartDataSet)
chartData.setDrawValues(false)
horizontalBarChartView.data = chartData
Here I also use some kind of hack because when one enters a value of 0.0 for a BarChartDataEntry the bars and the x axis have a significant offset. Therefore I create bars with a fake value and give them a transparent color.
Do one you had a similar issue with the library and know where it comes from ? Or maybe has even solved it ?
Thanks in advance for the help.
