Drill Down Combo Bar PRO uses the category structure of your data to create items on the Y-axis. Add your desired column to the Categories field, and the visual will match each category with the corresponding values in the Series fields.

There is no limit on how many categories can be in a column. The category field supports the following column types:

• Text
• Numbers
• Date
• Symbols

Adding multiple category columns (up to 9) to the Categories field will create a drill down hierarchy. The level order is determined by the category order in the Categories field, with the first category being the top level. You can rearrange the order by simply dragging the columns.
