2.10.1.3 index

The section 2.10.1.3 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 are separated by pairs of blank records. `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>+2<p>, 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 section 2.10.1.3 index is not specified, all sets are plotted as a single data set.

Example:

      plot 'file' index 4:5
