How to read from stdin? #34

Closed lodenrogue closed 4 years ago

Thank you for creating this project. I want to be able to read from stdin so I can do something like:

generate_csv_command | graph -o output.png

Hi! You can use - in place of a filename to graph from stdin:

cat samples/sine.csv | graph - -o sine.png

Confirmed working. Thank you!
