DataFart lets you easily graph data from the command line.
$ datafart < data.txt http://datafart.com/uensdk
Go to the url to see your data. Your data is only kept on the server for ten minutes, so open the url quickly.
$ open http://datafart.com/uensdk
$ cat example_data.txt 1.0 2.61 3.1 1.2 2.11 4.8 2.1 3.40 5.2
Data is organized into columns of numbers that will be parsed into 64bit floats.
Each line is scanned for numbers that match /[-+]?[0-9]+\.?[0-9]*/, and all other characters are ignored. Feel free to delimit using whitespace, commas or chess pieces:
$ echo ' 1 ♚ 2 ♛ 3 ♜ 4 ♝ 5 ♞ 6 ♟ 7 2 ♚ 3 ♛ 3 ♜ 4 ♝ 4 ♞ 5 ♟ 8 3 ♚ 4 ♛ 3 ♜ 4 ♝ 3 ♞ 4 ♟ 9' | datafart http://datafart.com/arkdnw
$ alias datafart='curl --data-binary @- datafart.com'
That's it. You might want to put that in your .bashrc
so it sticks around for a while.
