24 ## This is a modified version of plot() command to work with |
|
|
25 ## multiplot version of gnuplot to plot multiple plots per page. |
|
|
26 ## This plot version automatically updates the plot position to |
|
|
27 ## next plot position after making the plot in the given subplot |
|
|
28 ## position. |
|
|
29 ## |
|
|
30 ## See command plot() for the various options to this command |
|
|
31 ## as this is just mulitplot version of the same command. |
