New in version 4 of Gnuplot is a visual data analysis tool for complex, non-linear functions. New plots and graphs in Gnuplot are built by dragging, dropping and copying objects.

New in version 4, Gnuplot allows for complex, non-linear functions such as log-normal, lognormal and exponential. This gives more options for analysis in a simple plot.
