Using Axis column name for visual title?

Is there any way to create a dynamic title for a visualization, say a standard bar chart, that will grab the name of the Y or X column that is showing? For example if I have a bar chart with TOTAL_SALES along the X and CATEGORY along the Y, I want the title to be "CATEGORY". If I change the column to be TOTAL_SALES along the X and DEPARTMENT on the Y, I want the title to update to DEPARTMENT automatically.
