I was going to report an issue we were having regarding using a screen reader and Changing the Legend Label, which doesn’t seem to update. However, I came across a bug instead.
Under Advanced > Localization > Accessibility > Legend It used to have Legend Item > “Hide {itemName}” and Legend Label > “Toggle series visibility” (see screenshot 1) Now it seems to have taken on the properties of the Chart context menu, the Legend Label now says “period” and Legend Label No Title is “Download CSV” (see screenshot 2). The screen reader still announces Hide {itemName} and Toggle series visibility .
Onto the original issue, ideally we want to put something more useful for the screen reader user. Right now it says “Toggle series visibility”. I have the ability to change it, but it doesn’t actually apply.
