I am trying to implement Bordaigorl's answer to create pie charts with patterns. However, with my MWE I get the following errors:
Package pgfkeys Error: I do not know the key '/tikz/slice type/.style 3 args' and I am going to ignore it. Perhaps you misspelled it.
I modified the slice type (in MWE) in pie chart to get a third argument for patterns, which does not work as I expected. How to get patterns in slice types in Tikz pgf?
