iOS Charts - LinechartView issue - ios

Question

I wanted to remove 'description text' view, 'data set' view (square shape view below the graph). I am using iOS Charts library - LineChartView
import Charts
---------------------- class declaration -------------------
#IBOutlet var graphEmotionsView: LineChartView! // Class outlet variable
let paramsList = ["","Anger" , "Disgust", "Fear", "Joy", "Sadness",""]
let paramsListVal = ['give some values']
In viewdidload
//Set graph emotions view befor applying the data
self.graphEmotionsView.backgroundColor = UIColor.lightGrayColor()
//Gestures
self.graphEmotionsView.doubleTapToZoomEnabled = false
self.graphEmotionsView.pinchZoomEnabled = false
//Highlight per tap
self.graphEmotionsView.highlightPerTapEnabled = false
self.graphEmotionsView.highlightPerDragEnabled = false
self.graphEmotionsView.highlightFullBarEnabled = false
//X
self.graphEmotionsView.xAxis.labelPosition = .BottomInside
self.graphEmotionsView.xAxis.labelTextColor = UIColor.whiteColor()
var yVals1 : [ChartDataEntry] = [ChartDataEntry]()
for i in 0 ..< emotionParamsValues.count {
yVals1.append(ChartDataEntry(value: emotionParamsValues[i], xIndex: i+1))
}
print("yValues: \(yVals1)")
let set2: LineChartDataSet = LineChartDataSet()
set2.yVals = yVals1
set2.label = ""
set2.visible = true
// set chart line
set2.mode = .CubicBezier
set2.axisDependency = .Left
set2.lineWidth = 2.5
set2.setColor(UIColor(red: 157/255.0, green: 0/255.0, blue: 38/255.0, alpha: 1.0))
set2.highlightColor = UIColor.whiteColor()
// set custom point
set2.drawCirclesEnabled = true // should be true if you want hollow circles
set2.drawCircleHoleEnabled = true
set2.circleHoleRadius = 5.0
set2.setCircleColor(UIColor(red: 157/255.0, green: 0/255.0, blue: 38/255.0, alpha: 1.0))
// set fill chart
set2.drawFilledEnabled = true
set2.fillAlpha = 240 / 255.0
set2.fillColor = UIColor(red: 237/255.0, green: 26/255.0, blue: 103/255.0, alpha: 0.9)
var dataSets : [LineChartDataSet] = [LineChartDataSet]()
dataSets.append(set2)
dataSets[0].notifyDataSetChanged()
let data: LineChartData = LineChartData(xVals: emotionParamsList, dataSets: dataSets)
data.setValueTextColor(UIColor.whiteColor())
self.graphEmotionsView.data = data
Output I am getting

For fixing the description, try:
chart.description = ""
For disable the legend, try:
chart.legend.enabled = false
Shameless plug - you can find ios charts examples at ioscharts.io
