Final answer:
Mishik selected 'All Fields' under Target Highlighting for a dashboard action to ensure comprehensive highlighting across all fields in the visualization, enhancing interactivity and data representation consistency across multiple related visualizations.
Step-by-step explanation:
Mishik created a highlight action on a dashboard, selecting All Fields under the Target Highlighting. By choosing this option, Mishik aims to have the highlight action applicable to all the fields available in the visualization. This way, when an element in one part of the dashboard is selected, all instances of that element across all fields will be highlighted. This comprehensive approach enhances the interactive experience and ensures that all relevant data, not just a subset, is brought to the viewer's attention.
It is especially useful when the dashboard contains multiple related visualizations and the user wants to see how a particular data point is represented across the entire dashboard. For example, if Mishik's dashboard includes different charts that display various aspects of sales data, clicking on a specific product in one chart will highlight that product's data across all charts.
