plot(++Data, +Options, +Format, +OutputFile)

Data

The data to be plotted, array or list.

Options

Options list

Format

Output file format (atom or string)

OutputFile

Name fo file to store plot in (atom or string)

Description

Plots the data to a file in the specified format.

The Data can either be a list or a nested list of a 1D or 2D array of y values or x-y points.

The output format is defined as being the 'terminal' setting for gnuplot.

Syntax note: wherever gnuplot expects a string as an option value, use a double-quoted ECLiPSe string - unquoted or single-quoted atoms will not work!.
