helm: helm-create-plots errors

Hello,

When I try to run helm-create-plots --suite v1 outside the presentation directory, i.e, outside helm/src/helm/benchmark/presentation; I get following error:

FileNotFoundError: [Errno 2] No such file or directory: '/home/helm/benchmark_output/runs/v1/groups/the_pile.json'

Is this expected behavior? In the docs, I did not find any details in regards to running the command in a specific directory.
