Introduction to Charts in SwiftUI
When it comes to presenting information to users, easier is better.
Especially when we're dealing with large sets of data. We have different options like custom views, tables, summaries, etc. However, we can take a much richer experience path, and use some graphical presentation.
By using charts, users can get, at first sight, a better understanding of the data presented.
If you're looking to elevate your app's engagement, let me show you a quick, easy-to-follow guide on how we leverage charts to do it.
The basics
We create a chart by composing a series of chart elements. These elements must conform ChartContent
protocol and represent types that can be drawn in a chart's scope.
To create a chart, we use the init(content:)
method. In the ViewBuilder closure, we add all the visual elements needed.
struct ChartView: View {
var body: some View {
ChartView {
// Chart elements
}
}
}
