Purpose of this worksheet: using with the map to perform point source
Steps to take:
- Drag sample date to column shelf and drill it down to month granularity
- Drag location and measure to row shelf in order
- Put value on row shelf and choose average as aggregation method
- Add value to color card and choose average as aggregation method
- Drag location and measure to filter
