Saving graphical output

You can save histograms, scatter plots, and response plots in various formats, including Portable Network Graphics (PNG) and Graphics Interchange Format (GIF). You can save a histogram or plot after you create it when, on the Preferences menu, Plot Options is Interactive or View-Only.

To save a plot created with View-Only selected, do the following:
1. In the plot window, on the File menu, click Save As.
  The File Selector window appears.
2. Open the folder in which you want to save the histogram, scatter plot, or response plot, and then in the File name box, type a name.
3. In the Files of type list, select one of the following:
  - Portable Network Graphics (.png)
  - PostScript (.ps)
  - Graphics Interchange Format (.gif)
  - Data File (.dat)
  - Text File (.txt)
4. Click Save.
To save a plot created with Interactive selected, do the following:
1. Set the terminal type using the syntax set terminal <terminal_type>, where <terminal_type> defines the output file format.
  Available options for the format of the output file include: Portable Network Graphics (png), PostScript (postscript), Graphics Interchange Format (gif), and Joint Photographic Experts Group (jpeg).
  
  For example:
  
  set terminal png
2. Press Enter.
3. Set the output file name using the syntax set output "<filename>", where <filename> defines the name of the output file including an optional file path and the file extension.
  For example:
  
  set output "c:/histogram1.png"
  
  Note: If you do not specify a path, your output file will be saved by default in the user folder of your CATALYST Professional installation.
4. Press Enter.
5. Type replot, and then press Enter.
  Your plot is saved in the format and with the file name you specified.
