Interactive Map Legend

rayni.kertadjaja Sep 21, 2015 8:39 AM

Greetings!

I was wondering if there is a way to add interactivity to the Legend of a Filled Map.

For example, we have a Filled Map of the US with the Legend showing a range from dark green to light green with values 18 to 63.86:

As we hover over each of the stepped colors, we would like the States that fall in that category to be highlighted on the map.

Is this an available feature? I am relatively new to Tableau and am therefore not fully aware of all its capabilities just yet.

We are on Tableau 9 and currently using Excel as our sample data set.

Thanks in advance!

I don't this is possible. However you could create your own banding's and use those as a key which you can highlight.
Best way to do this would be to create bins but calculated groups would be better.

Hi David,

Thank you for your response. I'm relatively new to Tableau still; can you elaborate on what Calculated Groups are?

Thank you so much!

I'm not sure that this would work since the values can change depending on the time period selected. We are allowing the users to select anywhere from 1 day to the entire data set, so the range will vary greatly.

Seems like this is just not doable in Tableau (yet?). Thank you for the suggestions, though. I really appreciate it. =)

I think you can accomplish what you want with a custom step legend:

I just re-created it in our workbook (different calculations, ranges, etc.) and it works! Thank you so much! =)
