   Is there a mechanism to capture gnuplot warnings such as:

   Warning: empty y range [0:0], adjusting to [-1:1]

   so that these can be handled in Ruby instead of being output to stderr?

   So if I run a Ruby app using ruby_gnuplot that warning is printed to the console if I have missing data. I believe it is a warning printed to stderr from gnuplot itself. Such errors can be captured in a IO using popen3 AFAIK.
