How do I remove the dots in LineChartView iOS charts

Set the .setDrawCircles = NO; of your LineDataSet set to disable the drawing of circle.

It was on the wiki...
https://github.com/PhilJay/MPAndroidChart/wiki/DataSet-classes-in-detail

lineChartDataSet.drawCirclesEnabled = false

to remove value alone in a circle

lineChartData.drawValuesEnabled = false

In addition to the answers, you can use these properties to make your line more smooth

lineChartDataSet.drawCirclesEnabled = false
lineChartDataSet.drawCubicEnabled = true

or you can use mode property as drawCubicEnabled property is deprecated

lineChartDataSet.mode = .cubicBezier
lineChartDataSet.cubicIntensity = 0.2
