Prerequisite

Synopsis

This is the class that a programmer should instantiate if he wants to open a "device" to plot to. The device might be local, or it might be remote (i.e., running under Glish). The philosophy of the plotting interface is described in the PGPlotterInterface documentation.

It is possible that the object might not be attached to a valid plot device (for example, the user might have said "no plotting." Programerss should check the isAttached() member before plotting. If you attempt to plot to an unattached plotter, an exception is thrown.

Copying a PGPlotter uses reference semantics – after copying plotting on the old and new objects will result in the plot commands appearing on the same device. The device is closed only when the last reference is destructed.

You can detach a plotter from a device with the detach() call. If there are no other references to the plotter, this will close the device. (What it actually does is call the destructor on the object. For a local PGPPLOT device this will close it).

Example

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

Constructor & Destructor Documentation

casacore::PGPlotter::PGPlotter ( )

The default constructor does not attach to any plotter, that is isAttached() returns False.

An exception is thrown if you attempt to plot to an unattached PGPlotter.

casacore::PGPlotter::PGPlotter ( const String device,
uInt  mincolors = 2,
uInt  maxcolors = 100,
uInt  sizex = 600,
uInt  sizey = 450 
)

Create PGPlotter object using the curreent create function.

casacore::PGPlotter::PGPlotter ( PGPlotterInterface )

Create from the given PGPlotterInterface instantiation.

It takes over the pointer.

casacore::PGPlotter::PGPlotter ( const PGPlotter other)

Copies use reference semantics, i.e.

after copying the new and old copy both draw onto the same surface.

virtual casacore::PGPlotter::~PGPlotter ( )
virtual

If this is the last reference, close the plot.

Member Function Documentation

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).

Thrown Exceptions

  • An AipsError will be thrown if the plotter is unattached.

This is an emulated standard PGPLOT command.

It returns a record containing the fields:

[ok=Bool, x=Float, y=Float, ch=String];
If the remote device cannot do cursor feedback, ok==F.

Implements casacore::PGPlotterInterface.

void casacore::PGPlotter::detach ( )

Detach from the object.

If this is the last reference to the object, call its destructor (this will call pgclos on a local device).

This is not a standard PGPLOT command.

In the Glish/PGPLOT window, it puts a message in the message line. By default it sends it to the logger. In any event, this is intended for short helpful messages (e.g. saying which keys to press to mark a spectrum).
