Pivot Chart depicting percentage of total of single colum

I have tried to figure out how to get a pivot chart that depicts the percentage value of each category (e.g., FARM, MARKET) of the total for all categories within one column. In reference to the attached example of both the problem and desired result, I would like to know the percentage for each supplier of the total value of all suppliers and have this visualized in a pie chart. Is there anyway a pivot can accomplish this? Or am I to use normal tables?
