Are you creating a stacked bar chart by any chance? I have run into the same problem, where VoiceOver seems to ignore the accessibilityLabel and accessibilityValue modifiers we apply to each BarMark. However, this only happens with a stacked bar chart. With a standard bar chart, the modifiers work exactly as expected.

Can you try omitting this line from your chart? BarMark(x: .value("Month", x, unit: .month), y: .value("Revenue", y.revenue)) That should result in a chart that only shows the green income bars. In that case, applying the accessibilityLabel and accessibilityValue modifiers to each BarMark should produce the custom VoiceOver output you specify.
