Detailed Description

Plot to a PGPLOT device "local" to this process.

Intended use:

Public interface

Review Status

Date Reviewed:: yyyy/mm/dd

Prerequisite

PGPlotterInterface

Etymology

"Null" is used to denote that no plotting is done

Synopsis

Generally programmers should not use this class, instead they should use PGPlotter instead.

This class make a concrete PGPlotterInterface object which calls PGPLOT directly, i.e. PGPLOT is linked into the current executable.

Example

        // plot y = x*x
        Vector<Float> x(100), y(100);
        indgen(x);
        y = x*x;
   
        PGPlotterNull plotter("myplot.ps/ps");
        plotter.env(0, 100, 0, 100*100, 0, 0);
        plotter.line(x, y);

Motivation

It might be necessary to call PGPLOT directly in some circumstances. For example, it might be too inefficient to pass a lot of Image data over the glish bus.

To Do

Add more plot calls.

Constructor & Destructor Documentation

casa::PGPlotterNull::PGPlotterNull ( const String & device )

Open "device", which must be a valid PGPLOT style device, for example /cps for colour postscript (or myfile.ps/cps if you want to name the file), or /xs or /xw for and X-windows display.

Thrown Exceptions

An AipsError will be thrown if the underlying PGPLOT open fails for some reason.

virtual casa::PGPlotterNull::~PGPlotterNull ( ) [virtual]

The destructor closes the pgplot device.

casa::PGPlotterNull::PGPlotterNull ( const PGPlotterNull & ) [private]

Undefined and inaccessible

Standard PGPLOT commands.

Documentation for the individual commands can be found in the Glish manual and in the standard PGPLOT documentation which may be found at http://astro.caltech.edu/~tjp/pgplot/. The Glish/PGPLOT documentation is preferred since this interface follows it exactly (e.g. the array sizes are inferred both here and in Glish, whereas they must be passed into standard PGPLOT).
