Question 1

How to change line color and width in FSLineChart?

Accepted Answer

Set the color and lineWidth properties before calling setChartData, as shown in the README. For instance, use lineChart.color = UIColor.red and lineChart.lineWidth = 2.0 to customize appearance.

Question 2

FSLineChart vs iOS Charts framework: which should I use?

Accepted Answer

FSLineChart is lighter and simpler for line charts only, with easy customization, while Charts supports multiple chart types but is bulkier. Choose FSLineChart if you only need line charts and prefer minimal setup.

Question 3

Does FSLineChart work with SwiftUI?

Accepted Answer

FSLineChart is UIKit-based, so it can be integrated into SwiftUI using UIViewRepresentable for bridging, but it doesn't have native SwiftUI support, requiring additional code.

Question 4

How to animate chart drawing in FSLineChart?

Accepted Answer

Use the animationDuration property to control the speed; set it to a value like 1.0 for a one-second animation, as mentioned in the properties list for smooth rendering.

Question 5

Can FSLineChart handle real-time data updates efficiently?

Accepted Answer

You can update data by calling setChartData again, but it lacks built-in optimizations for smooth real-time updates, such as incremental rendering or performance tweaks for large datasets.

Question 6

Where can I find more examples or documentation for FSLineChart?

Accepted Answer

Beyond the basic GitHub example and reference to ChartLoot project, community resources are limited; developers may need to rely on trial-and-error or inspect the source code for advanced usage.
