I created a map with locations plotted in Tableau and have utilized a background map from NOAA to show which locations are being impacted by excessive rainfall. How do I filter the data so only those that fall within the excessive rainfall areas appear on the map? Alternatively how do I get aggregate measures of the locations that fall within the excessive rainfall zone?
It's not a perfect solution, but one method that I found success with is creating a filter action and then using the lasso selection tool on the dashboard to select all of the points within the desired area in order to filter the desired values. More info on the filter action can be found here.
