danielgindi/iOSCharts library : x axis label in horizontal bar chart - ios

Question

with the following code
barchart.xAxis.labelTextColor = UIColor.white
barchart.xAxis.labelPosition = .topInside
barChart.xAxis.setLabelCount(7, force: true)
Issue: x axis grid get destructed
barchart.xAxis.labelTextColor = UIColor.white
barchart.xAxis.labelPosition = .topInside
Issue: Right side Label gets hidden
Solution Required:
Need Following to be fixed:
*Grid should be aligned
*Label should be viewed
my code is :
barChart.legend.enabled = false
barChart.xAxis.labelTextColor = UIColor.white
barChart.xAxis.labelPosition = .topInside
barChart.leftAxis.drawAxisLineEnabled = true
barChart.leftAxis.enabled = true
barChart.leftAxis.drawGridLinesEnabled = false
barChart.rightAxis.drawAxisLineEnabled = false
barChart.rightAxis.drawGridLinesEnabled = true
barChart.rightAxis.drawLabelsEnabled = true
barChart.rightAxis.labelFont = NSUIFont.systemFont(ofSize: 13.0)
barChart.xAxis.labelFont = NSUIFont.systemFont(ofSize: 16.0)
barChart.rightAxis.labelTextColor = UIColor.white
barChart.leftAxis.axisMinimum = 0.0
barChart.rightAxis.axisMinimum = 0.0
barChart.rightAxis.drawLabelsEnabled = false
var dataEntries: [ChartDataEntry] = []
for i in 0..<dataPoints.count {
let dataEntry = BarChartDataEntry(x: Double(i),yValues: [values[i]])
dataEntries.append(dataEntry)
}
let chartDataSet = BarChartDataSet(values: dataEntries, label: "HB2")
let chartData = BarChartData(dataSet: chartDataSet)
chartData.setValueFormatter(DefaultValueFormatter(formatter: formatter))
barChart.xAxis.valueFormatter = IndexAxisValueFormatter(values:dataPoints)
barChart.data = chartData

Answer 1

First of all label position should be barchart.xAxis.labelPosition = .top and I do not understand why grids are not aligned but if you use following code it should be right aligned it worked for me.
chartView.legend.enabled = false
// chartView.xAxis.labelTextColor = UIColor.white
chartView.xAxis.labelPosition = .top
chartView.leftAxis.drawAxisLineEnabled = true
chartView.leftAxis.enabled = true
chartView.leftAxis.drawGridLinesEnabled = false
chartView.rightAxis.drawAxisLineEnabled = false
chartView.rightAxis.drawGridLinesEnabled = true
chartView.rightAxis.drawLabelsEnabled = true
chartView.rightAxis.labelFont = NSUIFont.systemFont(ofSize: 13.0)
chartView.xAxis.labelFont = NSUIFont.systemFont(ofSize: 16.0)
chartView.rightAxis.labelTextColor = UIColor.white
chartView.leftAxis.axisMinimum = 0.0
chartView.rightAxis.axisMinimum = 0.0
chartView.rightAxis.drawLabelsEnabled = false
var dataEntries: [ChartDataEntry] = []
for i in 0..<unitsSold.count {
let dataEntry = BarChartDataEntry(x: Double(i),yValues: [unitsSold[i]])
dataEntries.append(dataEntry)
}
let chartDataSet = BarChartDataSet(values: dataEntries, label: "HB2")
let chartData = BarChartData(dataSet: chartDataSet)
chartView.xAxis.valueFormatter = IndexAxisValueFormatter(values: months)
chartView.data = chartData
chartView.animate(yAxisDuration: 2.5)
I have removed your first formatter I do not understand why you used it but it gave me following chart.

Answer 2

as per my exprience you need to add lableCount in your chart configuration like below so that it will calculate proper xAxis and show it on your chart
horiBarChartView.xAxis.labelCount = <yourXAxisArray>.count
If we are not setting this count some time it will not able to generate proper xAxis position on chart.
So try this once and let me know its working or not.
