X/Y coordinates being rounded to whole numbers instead of being presented as decimals

[varunjitsingh6410]

Hi all.

I am currently attempting to generate a scatterplot graph where many of the coordinates should be decimals. However, the values keep getting rounded to the closest whole number and I am not sure why nor can I find a solution.

The above is a picture of the graph that is being generated. At the marker selected the points should be (x: 3/500 ; y: 3/500).

The code used to generate the graph is as follows:

for i in 0..<num {
            
            let coords = ChartDataEntry(x: Double(i/500), y: Double(i/500), data: ("Testing if points are decimal" as! String))
            dataPoints.append(coords)
}
        
self.graphView.drawMarkers = true
let marker:BalloonMarker = BalloonMarker(color: UIColor(red: 93/255, green: 186/255, blue: 215/255, alpha: 1), font: UIFont(name: "Helvetica", size: 12)!, textColor: UIColor.white, insets: UIEdgeInsets(top: 7.0, left: 7.0, bottom: 25.0, right: 7.0))
marker.minimumSize = CGSize(width: 75.0, height: 35.0)//CGSize(75.0, 35.0)
self.graphView.marker = marker

let set1 = ScatterChartDataSet(entries: self.dataPoints, label: self.graphName)
let data = ScatterChartData(dataSet: set1)
self.graphView.data = data
self.graphView.setVisibleXRangeMaximum(6)

Essentially my question is how can I get the correct decimal points mapped onto the graph without them being rounded?

So it ended up being a non-charts related problem and something dumb I missed. i was not being casted to a double which is what cause the rounding error. The issue was resolved where I directly casted i into a double (e.g. Double(Double(i)/500)
