FPLOT is a plotting program that converts directly from ASCII data to postscript output that is ready to print (or viewable on screen with a tool such as ghostview / ghostscript).

The input data file is simply an ASCII file where the numbers are delimited by spaces, tabs, and/or commas.

There is also an optional command file. This file is also ASCII and this is used to dictate to fplot how you want the plot to look. The syntax of a command file is very similiar to GNUPLOT. There is a link at the bottom of this page to view a sample command file.

Some of the key highlights of FPLOT are as follows:

• Command line interface, ideal for use in batch files/scripts.
• Sample command files and data files are included.
• Plot an infinite number of data points (up to available disk space).
• Plot an infinite number of Y ranges using lines, symbols, or both.
• 128 labels positioned anywhere on the page.
• Variable font sizes for each label.
• Rotate each label to any arbitary angle.
• X axis may be linear or log scale.
• Post-processing program to put multiple plots on one page.
  NOTE: This program also works with GNUPLOT (postscript) output.

C source code is included as well as executables for DOS.

FPLOT can be used completely in a pipe. The default output is to stdout and the special filename of '--' will read from stdin. Hence, you can do :

program_that_outputs_ascii_data | fplot -r -t "title" -x "x_label" -y "y_label" -- | lp -dprinter
