As of March 28, 2017 I see no ability to apply anything but colour to bars or pie slices which then starts to run into a problem with the WCAG 1.4.1 Use of Color guideline. You cannot use colour alone to convey information and they have no method for you to apply a pattern or texture to actually support users with colour blindness.
The strange thing is the line graph does have options to allow you to control the appearance of the line (dots, dashes, more than just colour). So using the other graphs (unless I'm totally missing something that isn't in the docs or shown anywhere) you basically fail 1.4.1 (Level A) because these charts are an issue for people with colour blindness (one who happens to be my boss in our provincial government so this won't fly). And for people who will say "But you could...". Yes we also have a data table of the data which is read back for screen readers. But it is a bad solution to force sighted users to scan through a data table because the visual was too lazy to follow basic accessibility guidelines and provide options other than colour alone. http://www.colourblindawareness.org/colour-blindness/ https://www.w3.org/TR/WCAG20/#visual-audio-contrast-without-color On Monday, 19 September 2016 10:49:47 UTC-6, Jonathan Greenberg wrote: > > Is there still an accessibility feature with google charts and does it > work with material charts?
