setViewPortOffsets does not work on Horizontal BarChartView

[Schabaani]

I want to create offset for horizontalBarChart, However, it does not work.

           let ys1 = [model.totalIncome, abs(model.totalExpense)]

            var yse1 = ys1.enumerated().map { x, y -> BarChartDataEntry in
            return BarChartDataEntry(x: Double(x), y: y)
            }

            let count = 2
            let data = BarChartData()
            let ds1 = BarChartDataSet(values: yse1, label: "")
            ds1.colors = [UIColor.red, UIColor.blue]

            // Number formatting of Values
            ds1.valueFormatter = YAxisValueFormatter()
            ds1.valueFont = UIFont(fontType: .H6)!
            ds1.valueTextColor = UIColor.dark_text
            ds1.iconsOffset = CGPoint(x: 350.0, y: 350.0)

            // Data set
            data.addDataSet(ds1)
            horizontalBarChartView.data = data

            // General setting
            horizontalBarChartView.xAxis.drawLabelsEnabled = false
            horizontalBarChartView.setScaleEnabled(false)
            //horizontalBarChartView.zoomToCenter(scaleX: count > 6 ? CGFloat(count) / 6.0 : 1.0, scaleY: 1.0)

            // Grid
            horizontalBarChartView.xAxis.drawGridLinesEnabled = false
            horizontalBarChartView.leftAxis.gridLineDashLengths = [15.0, 15.0]
            horizontalBarChartView.leftAxis.gridColor = UIColor.palette_28
            horizontalBarChartView.rightAxis.drawGridLinesEnabled = false
            horizontalBarChartView.xAxis.valueFormatter = IndexAxisValueFormatter(values: ["A","b"])
            horizontalBarChartView.xAxis.granularityEnabled = true
            horizontalBarChartView.xAxis.granularity = 1
            horizontalBarChartView.xAxis.labelPosition = .bottomInside

            // Disable number formatting of leftAxis and rightAxis
            horizontalBarChartView.leftAxis.enabled = false
            horizontalBarChartView.rightAxis.enabled = false

            // setViewPortOffsets
            let digitCount = Int(data.yMax).digitCount
            let leftOffset: CGFloat = digitCount > 2 ? CGFloat((digitCount - 1) * 10) : 10.0
            horizontalBarChartView.setViewPortOffsets(left: leftOffset, top: 200, right: 100, bottom: 100)

            // https://github.com/danielgindi/Charts/issues/2063
            horizontalBarChartView.leftAxis.axisMinimum = 0

            horizontalBarChartView.data?.notifyDataChanged()

I created horizontalBarChartView programmatically

    lazy var horizontalBarChartView: HorizontalBarChartView = {
        let chartView = HorizontalBarChartView()
        chartView.contentMode = .scaleAspectFit
        chartView.drawBordersEnabled = false
        chartView.drawGridBackgroundEnabled = false
        chartView.gridBackgroundColor = UIColor.clear
        chartView.legend.enabled = false
        chartView.chartDescription = nil
        chartView.highlighter = nil
        chartView.clipsToBounds = true
        chartView.translatesAutoresizingMaskIntoConstraints = false
        return chartView
    }()

Hi, have you tried calling setViewPortOffsets as last thing you do? In general it should be done right after you set new data, but also any calls to notifyDataChanged() might override your offsets.

Hi, I have tried setViewPortOffsets as last line. However, it doesn't work and I don't use notifyDataChanged()

[liuxuan30]

you called horizontalBarChartView.data?.notifyDataChanged(), but did you call horizontalBarChartView.notifyDataSetChanged()?
