setVisibleXRange doesn't work

[abcdefz]

In my code, I wrote

        @IBOutlet weak var lineChart: LineChartView!
        ...
        ...
        let lineChartDataSet = LineChartDataSet(values: dataEntries, label: "Units Sold")
        let lineChartData = LineChartData(dataSet: lineChartDataSet)
        lineChart.data = lineChartData
        lineChart.setVisibleXRangeMaximum(20.0)

but I got

After I remove "lineChart.setVisibleXRangeMaximum(20.0)" and I got

So if I want to set visible x range and the func setVisibleXRange doesn't effect data, how can I do, could anyone help me?

---

And I try to do some same change in Charts-Demos. In file LineChartTimeViewController.m, line 155 I add "[_chartView setVisibleXRangeMaximum:20.0];" but it also doesn't work. Are there some errors in my code?

It's working on my side

[_chartView setVisibleXRangeMaximum:5];

but time line chart do seems weird, should be related to the time conversion. Are you able to tackle this issue?

Has anything been done on this issue? I have a very similar problem. When I segue to the ChartViewContoller and the default selection has data, the chart renders normally:

but if I segue to this view controller when the default selection doesn't have any data and then select an item that has data, it looks like this:

segue to this:

then select an item that has data:

Of course viewDidLoad is called when I segue to the view controller and as long as the default selection has data when I segue to it, I can select another item that has data or doesn't and the chart will continue to render properly. So the difference appears to be in viewDidLoad but I've tried everything I can think of but nothing fixes the problem. Here's my viewDidLoad:

 override func viewDidLoad() {
    super.viewDidLoad()
    
    view.backgroundColor = UIColor(hexString: "232B35")
    
    self.title = "1RM"
    
    chartView.delegate = self
    chartView.chartDescription?.enabled = false
    
    let leftAxis = chartView.leftAxis
    leftAxis.axisMinimum = 190
    leftAxis.labelTextColor = NSUIColor.white
    
    let xAxis = chartView.xAxis
    xAxis.labelPosition = .bottom
    xAxis.axisMinimum = 0
    xAxis.granularity = 1
    xAxis.axisLineWidth = 5
    xAxis.valueFormatter = self
    xAxis.labelTextColor = NSUIColor.white
    
    
    chartView.configureDefaults()
    chartView.rightAxis.enabled = false // this fixed the extra xAxis grid lines
    
    chartView.backgroundColor = NSUIColor(red: 35/255.0, green: 43/255.0, blue: 53/255.0, alpha: 1.0)
    
    fetchData()
    
    chartView.setVisibleXRangeMaximum(7)
    
    chartView.animate(yAxisDuration: 1.0)
}

I've tried putting chartView.setVisibleXRangeMaximum(7) in the method that sets the chart data but it doesn't make a difference.

Is there anything else I can try or is this a legitimate bug that hasn't been fixed yet?

Thanks

I posted a question on Stack Overflow about this issue.

setVisibleXRangeMaximum is working, I labeld bug because other issue.
Please try ChartsDemo first as I tried.

I just found out, ordering matters for this to work. You need to call setVisibleXRangeMaximum after chartView.data = data or notifyDataSetChanged

[Deyan-Petkov]

use zoom(float scaleX, float scaleY, float x, float y) method

myChart.zoom(3, 0, myChart.getX(), myChart.getY());
This will hide some of the content and let you swipe.
