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
to remove circle in a line
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
