[ethanfox]

How to I make it to where there is only one label for each data point in my linechart?

Below is what I have.

This is what I am trying to get:

setting granularity = 1 did not fix it for me. What else could it be??

chartView.xAxis.granularityEnabled = true
chartView.xAxis.granularity = 1

all the trick is in the formatter

I'm getting my dates from my Firebase database. It's the date of whenever someone reviewed a business. So they will not always be the same time apart - if that makes sense. And I am saving them into an array. So would I need the date formatter still?

Yes the whole solution is in the formatter
Go slowly

Would I need this also?
chartView.xAxis.valueFormatter = DateValueFormatter(miniTime : from, interval: hourSeconds)

this is the soluce....

I guess I'll never know. If you're only going to allude to random crap then don't reply

Here's what I got:
`class CustomLabelsAxisValueFormatter : NSObject, IAxisValueFormatter {

var labels: [String] = []


var dateFormatter : DateFormatter
var miniTime: Double


public init(miniTime: Double) {
    //super.init()
    self.miniTime = miniTime
    self.dateFormatter = DateFormatter()
    self.dateFormatter.dateFormat = "dd/MM HH:mm"
    self.dateFormatter.dateFormat = "dd/MM"
    dateFormatter.timeZone = NSTimeZone(abbreviation: "GMT+0:00") as TimeZone!
}



func stringForValue(_ value: Double, axis: AxisBase?) -> String {
   
    let date2 = Date (timeIntervalSince1970: (value * 3600 * 24) + miniTime)
    
    let count = self.labels.count
    
    guard let axis = axis, count > 0 else {
        
        return dateFormatter.string (from: date2)
    }
    
    let factor = axis.axisMaximum / Double(count)
    
    let index = Int((value / factor).rounded())
    
    if index >= 0 && index < count {
        
        return self.labels[index]
    }
    
    return dateFormatter.string (from: date2)
    
    
    

    
}

}
`

I found a simple solution. :)

` func setChart(dataPoints: [String], values: [Double]) {
   chartView.noDataText = "You need to provide data for the chart."

var dataEntries: [ChartDataEntry] = []

for i in 0..<dataPoints.count {
    let dataEntry = ChartDataEntry(x: Double(i)+0.5, y: values[i])
    dataEntries.append(dataEntry)
}

let chartDataSet = LineChartDataSet(values: dataEntries, label: "")
let chartData = LineChartData(dataSets: [chartDataSet])


chartDataSet.colors = [red]
chartDataSet.drawCirclesEnabled = true
chartDataSet.circleRadius = 16
chartDataSet.circleColors = [red]
chartDataSet.circleHoleRadius = 12
chartDataSet.circleHoleColor = UIColor.white
chartDataSet.lineWidth = 4
chartView.data = chartData

}`

Notice the +0.5.
