Gnuplot is indeed a program that I sometimes use to get some graphic
feedback. But it is far from perfect. The two major drawbacks I see in this
method are:

- Display is not progressive, I can only get the result when all data is
  written, since Gnuplot waits for all the data before plotting.

- Adding marks or something on the graphics can be quite awkward, and even
  require some rework of the program flow.
