Index

The index keyword allows only some of the data sets in a multi-data-set file to be plotted.

Syntax:

     plot 'file' index m{{:n}:p}

Data sets (surfaces for splot) are separated by pairs of blank lines. index m selects only set m; index m:n selects sets in the range m to n; and index m:n:p selects indices m, m+p, m+2p, etc., but stopping at n. Following C indexing, the index 0 is assigned to the first data set in the file. Specifying too large an index results in an error message. If index is not specified, all sets are plotted.

Example:

         plot 'file' index 4:5
