Radius Marking in Map chart gets lost in switching between marker layers

[Raju bhutu]

On a map chart, I have 2 marker layers - Earthquake layer & SWD water disposal layer. I am trying to define a 5 mile radius zone around a particular location (Lat, Long) and see what data is visible inside. I keep the Earthquake layer as Interactive layer, then define the 5 mile zone, this filters out the rest of the Earthquake data leaving only the Earthquake layer data inside the 5 mile zone. But SWD water disposal layer would still display all the data. As soon as I switch the interactive to SWD water disposal layer, my previously defined radius marking is lost and I am back to square one. There is no common unique identifier key between 2 marker layers (tables) to merge these 2 tables. My goal is to get data points from both marker layers within 5 mile radius (the center of this circle will be different for each time the analysis is done) and create plots using data fetched both marker layers. Any suggestions on how can I solve this?

The marking itself is not lost if you toggle the interactive layer. However, I don't understand you define your 5 mile zone, is it an additional geometry?
