IOS-Charts set maximum visible x axis values - swift

Question

I'm using ios-charts (https://github.com/danielgindi/Charts). I have a LineChartView with 12 values in the x axis.
This however is far too many to see at the same time, so I want to display only 5 and then let the user drag to the right to see the next.
I've tried this:
let chart = LineChartView()
chart.dragEnabled = true
chart.setVisibleXRangeMaximum(5)
let xAxis = chart.xAxis
xAxis.axisMinValue = 0
xAxis.axisMaxValue = 5.0
xAxis.setLabelsToSkip(0)
But still see all 11 values at the time. How can I only see 5?

Answer 1

I finally got it!
The correct answer is:
chart.setVisibleXRangeMaximum(5)
This however needs to be set after the data has been set in the chart (not in a configure before)
This did the trick for me

Answer 2

You should set the X axis's labelCount property of the chart view.
In objc,like this
_chartView.xAxis.labelCount = 5;
Swift
chartView.xAxis.labelCount = 5

Answer 3

Here is my finding!!
you don't need to really use label count
if you are using DefaultAxisValueFormatter, NEVER use this. a lot of errors pop ! just use no2.
chart.setVisibleXRangeMaximum(number) will do.
please put this after chart data setting here you can see detail
combinedChartView.data = combineData. //this need to come first
combinedChartView.setVisibleXRangeMaximum(2) //after data setting
