The two dimensional plotting tool can be run by using the command plot() to plot the files fort.7 and fort.8 after a calculation has been run, or using the command plot('foo') to plote the data in the files s.foo and b.foo.
The menu bar provides two buttons. The File button brings up a menu which allows the user to save the current plot as a Postscript file or to quit the plotter. The Options button allows the plotter configuration options to be modified. The available options are decribed in Table 4.7. In addition, the options can be set from within the CLUI. For example, the set of commands in Figure 4.16 shows how to create a plotter and change its background color to black. The demo script auto/07p/demo/python/plotter.py contains several examples of changing options in plotters.
Pressing the right mouse button in the plotting window brings up a menu of buttons which control several aspects of the plotting window. The top two toggle buttons control what function the left button performs. The print value button causes the left button to print out the numerical value underneath the pointer when it is clicked. When zoom button is checked the left mouse button may be held down to create a box in the plot. When the left button is released the plot will zoom to the selected portion of the diagram. The unzoom button returns the diagram to the default zoom. The Postscript button allows the user to save the plot as a Postscript file. The Configure... button brings up the dialog for setting configuration options.
