Whenever a user wants to add a field or a dimension to the chart, he can set the level of aggregation with the help of multilevel slider located at the top right of the Filters Panel. The number of fields or dimensions in the row or column determines the number of levels on the slider. On the contrast, measures are not reflected in the slider. Also adjusting levels on time series charts are unavailable at the moment.
In the following image, the effect of the slider on a chart with one level of aggregation for both rows and columns is displayed”

- If you hover over a setting on the slider you will see the name of the field or dimension corresponding to that value.
- Pivoting a chart causes the slider settings to be preserved and applied to the new target.
- Removing the currently selected level from a row or a column resets the slider to the total when you remove a field that is not selected then the level remains the same.
- Adding a field or a dimension to a row or column causes the number of levels of the slider to change reflecting your addition.
- Changing the order of the fields in a row or column causes the level of the slider to change to reflect the new level of the field to correspond to the selection.
