The idea here is to add the option to enable dynamic symbology updates of a map as filters are applied. This functionality would enable users to see a subset of the data with the symbology (e.g. quantile, natural breaks, etc.) refreshed for that subset.
Attached to this post are two screenshots to illustrate this idea. The attached example utilizes bivariate color symbology with the quantile method in a 2x2 color grid. The first image shows the entire U.S. with this symbology. In the second image, a filter that selects only Pennsylvania is applied and the symbology updates for only the state of Pennsylvania. (Notice how in the U.S. view, we see all 4 possible colors across the country but no pink in Pennsylvania; however, when the symbology is refreshed after the state filter is applied, we can see all four possible colors in the state of Pennsylvania).
This feature would be useful when end users have particular interest in only a subset of the data and would like the symbology to be calculated relative to only that subset.
Ideally, this feature would be available in any web application that has filtering capabilities (Operations Dashboard, Dashboard, WebAppBuilder, Insights, etc.).
