So, I am trying to make a viz more accessible to persons with disabilities. In meeting with our disability resources folks, they thought a good work around might be to allow individuals with visual impairments to select an "enhanced" version of the viz using a radio dial. Initially, the primary concern is on discrete variables, but could be applied to continuous as well. Basically, I would like to set a parameter that would allow the user to select the view that suits them.
So far I have tried the following:
The color changing works when the variables are applied to color separately, but not when I used the calculated field. Basically, the defaults from the original variables are not carrying over from the Is there a way around this?
My best guess would be adding a statement like <If [Enhancements]=1 then ((value labels)& color-palette="Tableau 10" elseif [Enhancement]=2 then ((value labels enhanced) and color-palette="Color Blind" end.>
Any help you could give would be greatly appreciated.
