IOS-Charts set maximum visible x axis values

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?

same issue here, but reverse, I want to show all the values of xAxis (I have 12 values but it shows only 6 of them!! ) did you find any solution for your problem ?? — Maryam Fekri, Jan 16 '17 at 11:59

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

"needs to be set after the data has been set" is to be noted. thanks – Saranjith Mar 23 '18 at 10:01
this helped me but brought another problem. As my x axis values are TimeInterval of each day in the month, all the x axis values are same, scrolling indefinitely. how can I fix this? for example, if first x point is 10/10/16 in dd/MM/yy format all the other values also is same even after unlimited scrolling. whats wrong in this? – Anuran Barman Aug 02 '19 at 11:59

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

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
