To fix the issue where a List widget selection is not affecting a Pie chart due to different datasets, what should be done?

To ensure that a List widget selection affects a Pie chart, both visual elements need to operate on the same dataset. By using the "Connect Data Sources" feature, you enable the integration of data from different sources or datasets, which allows the Pie chart to recognize the selections made in the List widget. This connection ensures that interactions within the List widget will filter and reflect appropriately in the Pie chart.

In scenarios where widgets operate from different datasets, there will be a disconnection between their interactions, leading to no effect from the List widget on the Pie chart. By establishing a connection between the datasets, you effectively align their data, facilitating a synchronized response to user inputs. Thus, the action of connecting data sources is essential to resolving the issue and allowing for coherent data analytics representation.
