IndexAxisValueFormatter behaves not as expected

[appleManic]

These are my coordinates to draw the scatter plot

[{ "y": 83.0, "x": 0.0 }, { "y": 73.0, "x": 15.0 }, { "y": 63.0, "x": 30.0 }.....]

my x axis is incrementing with 15 points. 0,15,30,45,50...

If I do not use IndexAxisValueFormatter, it draws

Where as If I use IndexAxisValueFormatter with the values [0,15,30...]. It draws xAxis wrongly

I'm using following chart properties. My chart is scrollable

chartView.setVisibleXRangeMinimum(3) chartView.setVisibleXRangeMaximum(200 chartView.setScaleEnabled(false) chartView.dragEnabled = true chartView.scaleXEnabled = false chartView.pinchZoomEnabled = false

//X axis let xAxis = chartView.xAxis xAxis.drawGridLinesEnabled = false xAxis.drawLabelsEnabled = true xAxis.labelPosition = .bottom

xAxis.granularity = 15

I'm suppose to change this 15, 30, 45 to Date format "hh:mm a" based on the first timestamp. I guess if the IndexAxisValueFormatter draws it correctly, date formatted string will also be correct. Please let me know what went wrong
