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
[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
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)
