Sometimes it is helpful to bucket measures into groups, and use those groups as a dimension.
Note: bucketing is available for columns designated as Measures within Chartio. If your column is designated as a Dimension, you'll need to change it to a Measure within your Schema Editor.
To create buckets from a measure, drag the measure column into the Dimensions input in a layer, then click the column to view its menu. Click the button labeled New Bucket and add buckets as needed. Click OK and then click Refresh Data to view changes.
