I think I have 'a' solution --- there may be better ways to do this.....
I created a Summary table which includes the COUNT of the occurrences of the particular entries in a column called 'ProductProblemCategory'
Then sorted the 'N Row' column so that the highest number of occurrences is the top row.
Added a column called 'order' which is just a list of numbers to help with the display order within GraphBuilder
Then combined the 'order' column with the 'ProductProblemCategory' column to produce a new column 'ProductProblemCategory_'
----- this new column has the 'order numbers' attached to the beginning of the string so that Graph Builder will place them in the preferred order....
The resulting graph ---- place the new column ProductProblemCategory_ on the x-axis and the 'N Row' in the Frequency box in the lower right of the GraphBuilder Control Panel
