- ## This is a modified version of plot() command to work with
- ## multiplt version of gnuplot to plot multiple plots per page.
- ## This plot version automatically updates the plot position to
- ## next plot position after making the plot in the given subplot
- ## position.
- ##
- ## See command plot() for the various options to this command
- ## as this is just mulitplot version of the same command.
