Question 1

Is PNChart still maintained in 2024?

Accepted Answer

The README doesn't indicate recent updates, and the project appears to be from the iOS 7-8 era, suggesting it might not be actively maintained for newer iOS versions. Check the GitHub repository for recent commits or issues to confirm.

Question 2

How to customize colors in PNChart?

Accepted Answer

You can customize colors by setting properties like 'color' on chart data objects, as shown in the line chart example with PNFreshGreen, or use 'rangeColors' for conditional coloring based on values. Refer to the README's code snippets for specific implementations.

Question 3

PNChart vs Charts by Daniel Gindi: which is better?

Accepted Answer

PNChart is simpler and focuses on basic chart types with animations, ideal for quick integrations. Charts by Daniel Gindi is more comprehensive, supporting a wider variety of charts and modern Swift, but has a steeper learning curve. Choose based on project complexity and Swift preference.

Question 4

Can I use PNChart with SwiftUI?

Accepted Answer

Not directly, as PNChart is built on UIKit and Objective-C. You would need to wrap it in a UIViewRepresentable for SwiftUI, which adds complexity. Consider native SwiftUI charting libraries for better integration.

Question 5

How to update chart data in real-time with PNChart?

Accepted Answer

Use methods like 'updateChartData' for line and bar charts, or 'updateChartByCurrent' for circle charts, as demonstrated in the 'Update Value' section. This allows dynamic data changes without redrawing the entire chart.

Question 6

What chart types does PNChart support?

Accepted Answer

PNChart supports line, bar, circle (pie), and scatter charts, as listed in the Key Features. It does not include more advanced types like radar or candlestick charts, which might limit complex data visualizations.
