Question 1

How do I use YOChartImageKit with SwiftUI?

Accepted Answer

Since it generates UIImage, you can wrap it in an Image view in SwiftUI. For example, create a chart image in a ViewModel and display it using Image(uiImage: chartImage). Refer to the README for basic setup with Swift.

Question 2

YOChartImageKit vs Charts library for iOS: which should I choose?

Accepted Answer

Choose YOChartImageKit for watchOS compatibility and lightweight static images, as it avoids UIView dependencies. For iOS with rich interactivity, animations, and more chart types, the Charts framework is better suited.

Question 3

Can YOChartImageKit handle real-time data updates efficiently?

Accepted Answer

It's not ideal for real-time updates because each change requires redrawing the entire image, which can be performance-intensive. Consider it for static or infrequently updated charts.

Question 4

How to add a legend or axis labels to YOChartImageKit charts?

Accepted Answer

The framework doesn't include built-in legends or labels; you'll need to manually draw them using Core Graphics or overlay UI elements separately, adding complexity.

Question 5

Is YOChartImageKit still maintained for modern iOS versions?

Accepted Answer

The README shows version 1.1 with requirements for older Xcode and watchOS, and there's no mention of recent updates. Check the GitHub repository for activity to ensure compatibility.

Question 6

How to customize the center label in a donut chart with YOChartImageKit?

Accepted Answer

Use the labelText and labelColor properties on YODonutChartImage, as shown in the README example. Set labelText to your desired string and labelColor for text appearance.
