Plotcli is a command line application (written in D) that can
create plots from text/csv files and from piped data, making it
useful during data analysis. Plotcli works best in combination
with other command line tools such as awk. Plotcli will ignore
any lines it does not understand, so it is safe to use with files
that contain non csv data as well. Typically I use it during
simulations, where I simulate data, which I pipe to a file and
then I plot it using plotcli:
plotcli < path/to/file
It will plot the data and save the plot to a file (by default
plotcli.png). Plotcli has a command line switch similar to tail
(-f) so that it will keep checking for new data until it is
killed with ctrl+c.
Plotcli is meant to be adaptive and will automatically adapt the
plot boundaries to encompass all the data.
