2. Grab yourself a cold 🍺.

Requirements

• Xcode 11+

Usage

Initial Setup

  let lineChart = SSLineChart()
  lineChart.chartMargin = 14
  lineChart.yLabelFormat = "%1.0f"
  lineChart.xLabels = (1...5).map{ $0.description }
  lineChart.yFixedValueMax = 100
  lineChart.yFixedValueMin = 20
  lineChart.yLabels = ["20", "60", "100"]
  lineChart.xLabelWidth = 15.0
  lineChart.yLabelHeight = 0
  lineChart.yLabelColor =  UIColor.white
  lineChart.xLabelColor =  UIColor.white
        
  let activityData = [45, 65, 30, 85, 40, 70, 83, 50]
        
  let data = SSLineChartData()
  data.lineColor = .white
  data.lineAlpha = 1
  data.lineWidth = 0.6
  data.itemCount = activityData.count
  data.getData = { index in
      let yValue = activityData[index]
      return CGFloat(yValue)
  }

  lineChart.chartData = [data]
  let chartImage = lineChart.drawImage()

Apply gradient

  lineChart.setGradientColor(colors: [.red, .orange], position: .topDown)
