DSS rightly utilizes sampling and filtering for efficiency in multiple places. Sampling and Filtering can be used in multiple places including Charts, Statistics, Column Analysis and more. However, it is not immediately clear what the sampling settings are when looking at a chart or a statistical card without explicitly clicking on the sampling and filtering section, which can lead to erroneous conclusions when looking at a dashboard. Here is my suggestion:
1. Allow setting Sampling and Filtering options for dashboards, charts, statistical analysis in one place for a project
2. Provide a visual cue on what the Sampling and Filtering options are for these without having to click Sampling and Filtering on every single chart.
