How do I remove the expanders on the X axis of a stacked bar chart?

How do I remove the expanders on this chart that I've circled?

Hi Quinn,

Generally, the expander means that there is a Toggle Visibility action set on the category group of the Graph. This would be added automatically if you provide more than one Category group to the Graph. You may check the linked screenshot for clarity.

You need to delete the Action (set it to None) to remove the expander.
