Description

Description

It would be great if fillpattern was supported in scatterternary plots.

Why should this feature be added?

Being able to apply different patterns to different areas of the ternary plot would help us satisfy the WCAG success criteria 1.4.1 (use of colour), specifically that "colour should not be the sole identifier".

Many thanks
