The Dish Plotter is the familiar AIPS++ pgplotter tool, modified for additional utilities and capabilities. Any activity or task within Dish which produces a plottable result, will automatically have the result displayed in the Dish Plotter; for example, selecting entries within the Results Manger, the SDRecord Browser, or Calculator Operation stack will plot the selection chosen. The plotter is arrayed as shown in Figure 8.
This is the standard pgplotter File menu. Open...: This operation will read in an plot file on disk written by the Save command. Save: This operation will write a vector plot file of the displayed image to disk. Save will write to the file specified in feature L (defaults to dish.plot). Preview...: This operation brings up a ghostview session with the currently displayed plot shown. This feature allows you to see how such a plot will look printed out on a page. Print: This operation will print the current spectrum. Save...: This operation will also write a vector plot file of the displayed image but allows you to specify the file name unlike the 'Save' feature and the quicksave button (feature L). Exit: Exits from the Dish Plotter; closes the frame.
This is the standard pgplotter Edit menu. Add commands...: This allows additional PGPLOT commands to be added to the existing plot. For example, additional labeling or fiducial lines may be easily added. The Add commands brings up a frame with a list of all of the available PGPLOT commands. Selecting one brings up a brief explanation along with the various arguments required. An example frame is shown in Figure 9.
Change commands...: This allows already executed commands to be altered. A frame is brought up with the existing list of PGPLOT commands which produced the displayed frame. Again selecting a command brings up a small explanation along with the arguments used in its execution. Cut, Copy, and Paste features are available to duplicate and add additional commands. An example session is shown in Figure 10.
This menu allows selection of four different plot styles: 1) Line (default), 2) Histogram, 3) Points and 4) Connected Points. This feature operates on the active (most recently displayed) plot in the frame.
This menu allows selection of five different line styles. This feature is only effective if the Line Plot Style is selected. The five line styles are: 1) Solid, 2) Dashed, 3) Dotted, 4) Dot-Dash, and 5) Dash-dot-dot-dot.
The header menu offers four levels of header information on each plot: 1) None (the default), 2) Stats which will give the rms and mean of the displayed plot and, if available, the rms and mean of selected baseline regions on the plot, 3) Brief which gives only information on the Source name, scan number, date and time, and 4) Full, which renders all of the above information plus values for the position, altitude, azimuth, frequency, channel resolution.

The color menu currently offers only two options. Normal which is the default black background and Reverse, which is a white background.
Four options for labeling the X-axis of a plot: 1) X-axis units: this will default to displaying whatever the default units of the plot are. In the case of the figure this is frequency, 2) Channel units: this will label the X-axis by channel number, 3) X-axis-Channel: this will label the bottom X-axis with the default units of the spectrum while the top will indicate the channel number, 4) Channel-X-axis: this is the reverse of three.
The overlays menu is a simple toggle switch between On and Off. In the Off mode, all new plot results or selections will clear the screen before plotting the new result. The only exceptions to this are the Baseline operation in Show mode, which will overplot the calculated baseline over the spectrum, and multi-channel data which will plot as many channels as found on the same screen. In the On mode, all new selections and results will be overplotted; the axes will be scaled, if necessary, to accomodate all overlayed plots.
Currently this menu offers only an unzoom feature. The unzoom handles the Dish Plotter zooming capability (the middle mouse button zoom), not the standard pgplotter zoom capability found in the Tools Menu. The middle mouse button zoom is required to appropriately handle overlayed plots; the pgplotter zoom will only zoom the active plot which is the last one plotted. This isn't generally a problem unless the axes for overlayed plots differ.
There are two tools offered. Zoom which is the standard pgplotter zoom capability. You may select either a boxed region or an X-axis or Y-axis zoom. Another button restores the plot to the full range.
The second tool is called LineID. This tool browses an aips++ table version of the Poynter and Pickett molecular line catalog, and plots any lines found that fall within the frequency range of the displayed plot. Line positions are plotted with short tick marks along the top of the plot while the corresponding molecular name tag is plotted vertically along the bottom.
Standard pgplotter help menu. The options are: 1) PGPlotter: this will drive your netscape browser to the help section on the PGPlotter. 2) Reference Manual: this will drive the browser to the Reference Manual main page. 3) About Aips++...: This provides basic information about the AIPS++ version being used.
This is the filename that the Save option in the File menu will save to by default. The default plotfile name is dish.plot.
Clears all currently displayed plots. Resets most plot parameters to their defaults. The color of displayed data resets to red, but line styles and plot styles previously selected will be retained.
The Redraw essentially re-executes all of the cached plot commands again. This becomes important if the plot has deviated from the original through, for example, command line additions.
Whenever the cursor is within the Dish Plotter frame, the cursor positions will be continuously read back. The coordinates shown are the X and Y position as defined by the X and Y axes' units. The channel number and Y-value of the cursor position are also displayed.
Dismisses or closes the Dish Plotter frame. The frame will be automatically re-opened if an action occurs which produces a plottable result, i.e., if a spectrum is selected, a new Dish Plotter frame will be initialized to display the selection.
