Good catch, @anukandimalla. I wonder if this is a setting we can change. Seems like showing the value for each bar would be an essential part of any library. @sarahscottr Is there a setting within tableau for this?

toribr commented 3 years ago

Actually @anukandimalla Is your primary concern with printing? On second thought, and depending on the chart type, adding values could essentially render the chart unreadable. I'm not sure we want to do that as a default.

anukandimalla commented 3 years ago

I am thinking it should be the default for mobile devices and when users print the charts- the aligned values will be helpful in reading the chart because the screen area is very less in mobile devices to open each tooltip to understand the value and also there is no possibility of interaction with screens/tooltips in the print version.

Not validated yet, just a thought - The screenreader interaction behavior of the data tooltips.

I also understand each assign values creates readability issues and also concerns with data quality for showing them in numbers but we can ideate other alternatives to make the charts more readable.

Yes, I see. Some reading I have done suggests using tables, but I need to look into it further. The multiple axes per chart will complicate matters, too.
