To make a chart or graph accessible using Swift Charts, you can leverage the built-in accessibility features. Swift Charts ensures that your charts are accessible by default. Here are some key points to consider:
-
VoiceOver Support: Swift Charts can describe the chart using VoiceOver. For example, it can describe the x-axis and y-axis labels and the data series present in the chart. This is fundamental to making data visualizations accessible to everyone.
-
Customizing Visual Elements: You can use modifiers to customize the appearance of your charts to make them more legible. For instance, you can change the color of a line plot or fill in the area below a curve to increase contrast and make the chart easier to understand.
-
Function Plots: Swift Charts allows you to plot mathematical functions and customize their appearance to ensure they are distinguishable and accessible.
For more detailed information, you can refer to the session Swift Charts: Vectorized and function plots (02:38).
