Examples

To display load average of the system, we can use the following command:

$ (while true ; do sed -e 's/\(.* .* .*\) .* .*/\1/' < /proc/loadavg ; sleep 5;done) \
   | ngrapher

It prints three values every five seconds, and as they are piped into ngrapher, you see this beautiful plot:

You can also graph csv files:

$ ngrapher < sin.csv

Get it

Download sources from git repository:

$ git clone http://piggledy.org/projects/ngrapher/ngrapher.git/

Then, compile it:

$ cmake .
$ make

You can now play with this tool, for example with random data:

$ ./input.py | ./ngrapher
