public class PlotApplication

extends PlotFrame

PlotApplication is a versatile two-dimensional data plotter application. It can read files compatible with the Ptolemy plot file format (currently only ASCII). For a description of the file format, see the Plot and PlotBox classes. Command-line options include:

-help

Print the usage, including all command-line options that exist for backward compatibility and then exit. The help menu choice will display the same information.

-test

Display the plot, then exit after 2 seconds.

-version

Print the program version and then exit. While ptplot is running, the version menu choice will display the same information.

-

Read the plot data from standard in.

For compatibility with historical applications, this application has a limited ability to read pxgraph files. The command line arguments must be used, and the options that are understood are exactly those of the pxgraph application, plus some more to allow for cross-platform reading. It is not possible to read pxgraph files using the "Open" menu command (because of the cross-platform problems). The additional command-line arguments are:

-bigendian

Data files are in big-endian, or network binary format. If you are on a little-endian machine, such as a machine with an Intel x86 chip, and you would like to read a binary format file created on a big-endian machine, such as a Sun SPARC, use the -bigendian flag.

-littleendian

Data files are in little-endian, or x86 binary format. If you are on a big-endian machine, such as a Sun Sparc, and you would like to read a binary format file created on a little-endian machine, such as Intel x86 machine, then use the -littleendian flag.

To compile and run this application, do the following:

 javac -classpath ../.. PlotApplication.java
 java -classpath ../.. ptolemy.plot.PlotApplication
 

This assumes a particular directory structure. If this is not what you have, then alter the above accordingly.
