Line charts

LineChartView with multiple lines! First release of this feature, interaction is disabled for now, I'll figure it out how could be the best to interact with multiple lines with a single touch.

Usage:

MultiLineChartView(data: [([8,32,11,23,40,28], GradientColors.green), ([90,99,78,111,70,60,77], GradientColors.purple), ([34,56,72,38,43,100,50], GradientColors.orngPink)], title: "Title")

Gradient colors are now under the GradientColor struct you can create your own gradient by GradientColor(start: Color, end: Color)

Available preset gradients:

  • orange
  • blue
  • green
  • blu
  • bluPurpl
  • purple
  • prplPink
  • prplNeon
  • orngPink

Full screen view called LineView!!!

 LineView(data: [8,23,54,32,12,37,7,23,43], title: "Line chart", legend: "Full screen") // legend is optional, use optional .padding()

Adopts to dark mode automatically

You can add your custom darkmode style by specifying:

let myCustomStyle = ChartStyle(...)
let myCutsomDarkModeStyle = ChartStyle(...)
myCustomStyle.darkModeStyle = myCutsomDarkModeStyle

Line chart is interactive, so you can drag across to reveal the data points

You can add a line chart with the following code:

 LineChartView(data: [8,23,54,32,12,37,7,23,43], title: "Title", legend: "Legendary") // legend is optional

Turn drop shadow off by adding to the Initialiser: dropShadow: false

Bar charts

[New feature] you can display labels also along values and points for each bar to descirbe your data better! Bar chart is interactive, so you can drag across to reveal the data points

You can add a bar chart with the following code:

Labels and points:

 BarChartView(data: ChartData(values: [("2018 Q4",63150), ("2019 Q1",50900), ("2019 Q2",77550), ("2019 Q3",79600), ("2019 Q4",92550)]), title: "Sales", legend: "Quarterly") // legend is optional

Only points:

 BarChartView(data: ChartData(points: [8,23,54,32,12,37,7,23,43]), title: "Title", legend: "Legendary") // legend is optional

ChartData structure Stores values in data pairs (actually tuple): (String,Double)

  • you can have duplicate values
  • keeps the data order

You can initialise ChartData multiple ways:

  • For integer values: ChartData(points: [8,23,54,32,12,37,7,23,43])
  • For floating point values: ChartData(points: [2.34,3.14,4.56])
  • For label,value pairs: ChartData(values: [("2018 Q4",63150), ("2019 Q1",50900)])

You can add different formats:

  • Small ChartForm.small
  • Medium ChartForm.medium
  • Large ChartForm.large
BarChartView(data: ChartData(points: [8,23,54,32,12,37,7,23,43]), title: "Title", form: ChartForm.small)

For floating point numbers, you can set a custom specifier:

BarChartView(data: ChartData(points:[1.23,2.43,3.37]) ,title: "A", valueSpecifier: "%.2f")

For integers you can disable by passing: valueSpecifier: "%.0f"

You can set your custom image in the upper right corner by passing in the initialiser: cornerImage:Image(systemName: "waveform.path.ecg")

Turn drop shadow off by adding to the Initialiser: dropShadow: false

You can customize styling of the chart with a ChartStyle object:

Customizable:

  • background color
  • accent color
  • second gradient color
  • text color
  • legend text color
 let chartStyle = ChartStyle(backgroundColor: Color.black, accentColor: Colors.OrangeStart, secondGradientColor: Colors.OrangeEnd, chartFormSize: ChartForm.medium, textColor: Color.white, legendTextColor: Color.white )
 ...
 BarChartView(data: [8,23,54,32,12,37,7,23,43], title: "Title", style: chartStyle)

You can access built-in styles:

 BarChartView(data: [8,23,54,32,12,37,7,23,43], title: "Title", style: Styles.barChartMidnightGreen)
