Hoping someone catches this on the local timeline for vis.social…

Has anyone created a stacked area chart style that passes WCAG without being a noisy mess of patterns? I’ve been fighting with this 5-source dynamic chart for a while and can’t seem to find a solution that doesn’t make it even harder to read.

Any help would be appreciated.
