X-Axis Labels not showing

[martheli]

I have the below function that I use to set up a simple bar chart. The resulting chat appears but with no x-axis labels on the chart at all. I am not sure if I missed something in my set up of the chart that would leave the x-axis labels off.

 func setChart(chartview: BarChartView, xarray: [String], yarray: [Double], count: Int){
        
        
        var dataEntries: [BarChartDataEntry] = []
        
        
        for i in 0..<xarray.count {
            
            let dataEntry = BarChartDataEntry(x: Double(i), y: Double(yarray[i]))
            
            dataEntries.append(dataEntry)
        }
        
        
        let chartDataSet = BarChartDataSet(values: dataEntries, label: "")
        
        chartDataSet.drawValuesEnabled = true
        
        let chartData = BarChartData(dataSet: chartDataSet)
        
        let format = NumberFormatter()
        
        format.numberStyle = .none
        
        let formatter = DefaultValueFormatter(formatter: format)
        
        chartData.setValueFormatter(formatter)
        
        chartview.xAxis.valueFormatter = IndexAxisValueFormatter(values:xarray)
        
        chartview.xAxis.granularityEnabled = true
        
        chartview.xAxis.labelPosition = .bottom
        
        chartview.chartDescription?.enabled = false
        
        chartview.rightAxis.axisMinimum = 0.0
        
        chartview.leftAxis.axisMinimum = 0.0
        
        
        chartview.legend.enabled = false
        
        chartview.xAxis.drawGridLinesEnabled = false
        
        chartview.rightAxis.drawLabelsEnabled = false
        
        chartview.rightAxis.drawGridLinesEnabled = true
        
        chartview.xAxis.setLabelCount(count, force: false)
        
        
        chartview.data = chartData
        
        
    }

Now I have it to where it only shows 1 xValue under the second bar in the chart. Anyone know how to get all of the Values to show up?

Even i am facing the same problem..X axis labels are not showing up in Barchart. And below is my code. Can any one help me out.

func setChart(dataPoints: [String], values: [Double]) {

    var dataEntries: [BarChartDataEntry] = []
    
    for i in 0..<dataPoints.count {
        let dataEntry = BarChartDataEntry(x: Double(i), y: values[i])
        dataEntries.append(dataEntry)
    }
    
    var chartDataSet = BarChartDataSet()
    chartDataSet = BarChartDataSet(values: dataEntries, label: "Work Orders")
    chartDataSet.colors = ChartColorTemplates.material()
    chartDataSet.valueFont = .boldSystemFont(ofSize: 15)
    
    let chartData = BarChartData(dataSet: chartDataSet)
    
    let format = NumberFormatter()
    format.numberStyle = .decimal
    let formatter = DefaultValueFormatter(formatter: format)
    chartData.setValueFormatter(formatter)
    
    barChartView.data = chartData
    barChartView.xAxis.granularity = 1
    barChartView.xAxis.granularityEnabled = true
        
    barChartView.xAxis.valueFormatter = IndexAxisValueFormatter(values:dataPoints)
    
    barChartView.xAxis.setLabelCount(dataPoints.count , force: true)
    
    barChartView.xAxis.drawGridLinesEnabled = false
    barChartView.xAxis.labelPosition = .bottom
    barChartView.xAxis.labelRotationAngle = 315
    barChartView.pinchZoomEnabled = false
    
    for datastring in dataPoints {
        if datastring.characters.count > 20 {
            barChartView.xAxis.labelRotationAngle = 270
            break
        }
    }
    
    barChartView.doubleTapToZoomEnabled = false
    barChartView.chartDescription?.text = ""
    barChartView.rightAxis.enabled = false
    barChartView.leftAxis.enabled = false
    barChartView.barData?.barWidth = 0.4
    barChartView.isUserInteractionEnabled = false
    
    barChartView.xAxis.avoidFirstLastClippingEnabled = false
    
    barChartView.dragEnabled = false
    
    barChartView.animate(xAxisDuration: 2.0, yAxisDuration: 2.0, easingOption: .easeInOutCubic)
}

Has this code worked fine before, or are you both new to using Charts? Is this still the case in 3.0.5 (just released)?

[georgeerol]

Yes, i'm having the same problem. It works fine with release 3.04 but not release 3.0.5.

[jjatie]

If anyone can investigate this, it would be appreciated. I will do my best to look into it this week.

[leedsalex]

@jjatie I have submitted a pull request that fixes this (#3174).

[jjatie]

PR accepted and will be deployed in the near future.

[liuxuan30]

@jjatie have you checked why causing this?

[jjatie]

Yes, I made a mistake in one of my commits. #3174 reverts it.
