Line chart xAxis cut left or right in iphone 5

[sergioliip]

Hello, I have tried to find the solution to my problem, but I have not found anything related. I hope you can help me.

My problem is that, sometimes, the line graph is cut by the beginning or the end, and I do not understand why.

I have tried to set the zoom, the maximum and minimum values, I have the granularity the number of fields, etc ...

This is my config:

`viewLineChart.dragEnabled = true
viewLineChart.dragDecelerationFrictionCoef = 0.95
viewLineChart.highlightPerDragEnabled = true
viewLineChart.legend.enabled = false
viewLineChart.rightAxis.enabled = false
viewLineChart.delegate = self
viewLineChart.drawGridBackgroundEnabled = false

    viewLineChart.pinchZoomEnabled = false
    viewLineChart.drawBordersEnabled = false
    viewLineChart.borderLineWidth = CGFloat(1)
    viewLineChart.borderColor = ApplicationConstants.getLiipDarkUIColorFromAlpha(customAlpha: 1)
    viewLineChart.drawBordersEnabled = false

viewLineChart.xAxis.valueFormatter = HourFormatter()
viewLineChart.xAxis.setLabelCount(3, force: true)

    viewLineChart.xAxis.labelCount = 3
    viewLineChart.xAxis.forceLabelsEnabled = true
    viewLineChart.xAxis.drawGridLinesEnabled = false
    viewLineChart.xAxis.drawLabelsEnabled = true
    viewLineChart.xAxis.drawAxisLineEnabled = true
    viewLineChart.xAxis.labelPosition = XAxis.LabelPosition.bottom
    viewLineChart.xAxis.labelTextColor = ApplicationConstants.getLiipDarkUIColorFromAlpha(customAlpha: 1)
    viewLineChart.xAxis.valueFormatter = HourFormatter()
    viewLineChart.xAxis.avoidFirstLastClippingEnabled = true
    viewLineChart.xAxis.granularityEnabled = false
    
    viewLineChart.leftAxis.granularity = Double(5)
    viewLineChart.leftAxis.axisMaximum = getLeftAxisMaximum()
    viewLineChart.leftAxis.axisMinimum = getLeftAxisMinimum()
    viewLineChart.leftAxis.drawZeroLineEnabled = false
    viewLineChart.leftAxis.drawAxisLineEnabled = true
    viewLineChart.leftAxis.drawGridLinesEnabled = false
    viewLineChart.leftAxis.drawLabelsEnabled = true
    viewLineChart.leftAxis.labelPosition = YAxis.LabelPosition.outsideChart
    viewLineChart.leftAxis.labelTextColor = ApplicationConstants.getLiipDarkUIColorFromAlpha(customAlpha: 1)
    
    
    markerView = MarkerView(frame: CGRect(x: -8, y: -8, width: 16, height: 16))
    markerView?.layer.cornerRadius = 8
    markerView?.backgroundColor = ApplicationConstants.getLiipUIColorFromAlpha(customAlpha: 1)
    markerView?.offset = CGPoint(x: -8, y: -8)

viewLineChart.xAxis.axisMaximum = with.getDataSetByIndex(0).xMax
viewLineChart.xAxis.axisMinimum = with.getDataSetByIndex(0).xMin

func formatDataSet(dataSet: LineChartDataSet) -> LineChartData{
dataSet.axisDependency = YAxis.AxisDependency.left

    var colors = getGravityColors(dataSet:dataSet)
    dataSet.circleColors = colors
    if colors.count > 1 {
        colors.remove(at: 0)
    }
    dataSet.colors = colors
    
    
    //Values
    dataSet.drawValuesEnabled = false
    //Circle
    dataSet.drawCirclesEnabled = true
    dataSet.drawCircleHoleEnabled = true
    dataSet.circleRadius = CGFloat(3)
    dataSet.circleHoleRadius = CGFloat(1.5)
    //HighLight
    dataSet.highlightEnabled = true
    dataSet.drawHorizontalHighlightIndicatorEnabled = false
    dataSet.drawVerticalHighlightIndicatorEnabled = false
    
    return LineChartData(dataSet: dataSet)
}`

what is with.getDataSetByIndex(0).xMax and with.getDataSetByIndex(0).xMin suppose to return?

[sergioliip]

Hi seenoevo,
The xMin is 10:30 and The xMax is 11:30

first

viewLineChart.xAxis.labelCount = 3
    viewLineChart.xAxis.forceLabelsEnabled = true

you should not use like this after viewLineChart.xAxis.setLabelCount(3, force: true). Just call open func setLabelCount(_ count: Int, force: Bool) instead.

This makes your x axis labels like (max - min) / labelCount directly, without more calculations. It starts from min, so you should check if min is within the boundary in XAxisRenderer. Later check if your formatted string are rendered in drawLabels(context: CGContext, pos: CGFloat, anchor: CGPoint)

Just add some break points to see if your first value is rendered. Ideally you should check if viewPortHandler.isInBoundsX(position.x) first. Sometimes it's just oob
