The session "Swift Charts: Vectorized and function plots" at WWDC 2024 introduces new capabilities in Swift Charts, focusing on function plots and vectorized plots. Swift Charts now allows for the visualization of mathematical functions, making it easier to create informative and accessible visualizations. The session covers:

  • Function Plots: These include line plots for visualizing single functions and area plots to fill in the area between two functions. Swift Charts supports plotting parametric functions and handling piecewise functions by using nan for undefined values.

  • Vectorized Plots: These are designed for efficiently processing larger datasets. The vectorized plot API, such as rectangle plots, allows for homogeneous styling of data points and can handle entire collections in parallel. This is useful for visualizations like scatterplots or heat maps.

  • Best Practices: The session provides guidance on when to use vectorized plots versus the mark API, emphasizing performance optimizations like using stored properties and grouping data by style.
