How can I quickly create a bar chart according to an individual category.
I have 2 columns for 150,000 people
First column lists hospitals (150 different hospitals)
Second column lists zipcodes where the person comes from (~2000 zipcodes)
I want to very quickly plot a bar chart for the zipcodes that people come from for an INDIVIDUAL hospital.
Preferably don't want to have to manually enter the value labels.
Thanks for helping!
