1. Tooltip configuration allows you to display additional information from the source dataset that is not directly plotted on the chart.
   
2. This enhances data visibility by providing contextual insights when users hover over chart elements.
   

1. Tooltip displays:
   

1. Plotted columns (already used in the chart)
2. Additional configured columns (added via Tooltip configuration)
   

1. The values shown are always contextual to the hovered data point (category/segment).
   

1. Suppose chart is plotted with configurations of -Region, Category and Profit (sum).

1. This chart is configured with the Tooltip Configuration available under Tooltip formatter: Category with ‘First’ aggregation, SubCategory with ‘First’ aggregation, Quantity with ‘Sum’ aggregation.
   

1. When a user hovers over a chart:
   

1. Tooltip shows values for:
   

1. Chart plotted columns
2. Tooltip-configured columns, as highlighted in below Figure.
   

1. As can be seen from below figure, the chart tooltip now shows additional information on same configuration of chart. Chart shows data for the hovered column plotted for: Region as Europe and Category as ‘Groceries’.
   
2. The tooltip configured data is shown as: First Category is Groceries, First SubCategory is Mobile and Sum of Quantity is 42 for the Region as Europe and Category as ‘Groceries’.
   
3. Thus, the data is for tooltip configured columns is aggregated based on the plotted category/categories, ensuring relevant information is displayed.
   

For Categorical Columns:

1. Count
   
2. Count Distinct
3. First (Default aggregation)
4. Last
5. Percentage (supported across Count and Count Distinct aggregations)

For Measure Columns:

1. Sum (Default aggregation)
   
2. Average
3. Count
4. Count Distinct
5. Maximum
6. Minimum
7. Percentage (supported across aggregations)

 

1. Navigate to Tooltip Formatter >> Expand >> Tooltip Configuration option is displayed.
2. Drag and drop columns from the dataset into the Tooltip section
3. Hover on added columns in Tooltip Configuration to see the gear icon.
4. Click gear icon and Configure aggregation as required.

1. Add new columns to tooltip
   
2. Remove existing columns
   
3. Update aggregation or column selection
   
4. Reorder columns (sequence defines display order)
   

1. Tooltip includes:
   
1. Chart-configured fields
2. Tooltip-configured fields
   
2. This is a chart-specific configuration (applies only to the selected chart)
3. The tooltip data is run-time data for the tooltip configured columns as per the chart configuration.
