Multiple csv support?

[0xbs0d]

Hi, is there any way of opening multiple csv files to be plotted together on the same graph?

Currently the only way is to use the --chain flag to chain multiple runs together. This is the third example in the README plotting sine and cosine:

graph samples/sine.csv --marker '' --chain | \
graph samples/cosine.csv --title 'sine and cosine' \
  --ylabel '' --xscale 250 --marker '' -o sine-cosine.png

Notice that --chain is used in the first call and piped into the second call, which uses -o to output a file.
