title: Display legends for particular worksheet when switching between plots in tableau dashboard using parameters
body: <p>I am trying to develop a dashboard which will have different level of detail depending upon the user input. I have two maps, one showing data to the granularity of county and another one by zip codes. I am able to toggle between the graphs but the legend do not appear to toggle and remain on the screen. The link to the dashboard: <a href="https://public.tableau.com/profile/rohan.verma#!/vizhome/Zip-County/Dashboard3?publish=yes" rel="nofollow noreferrer">https://public.tableau.com/profile/rohan.verma#!/vizhome/Zip-County/Dashboard3?publish=yes</a></p>
  
  <p>Any help to display the legend for only the view would be appreciated. I am also open to suggestions on doing this in a different way.</p>
