.SH NAME 
.B prochart - ProChart Graphics Presentation Program
.SH SYNOPSIS
prochart
[
.B \-i
]
[
.B \-f filename
]
.SH DESCRIPTION
.I ProChart 
is a menu-driven graphics presentation program that allows
you to make line charts, bar charts, and pie charts, and to easily
modify the appearance of your charts.  
It can be run from any graphics terminal, but currently the only
hardcopy method is a screen dump.
.PP
.I ProChart
is the most user-friendly and also the most limited of three companion
graphics packages:  
.I ProChart,
.I CChart,
and 
.I GKS.
If you have no programming experience, and you want to make simple
charts easily and quickly, you will probably want to use
.I ProChart.
.I CChart 
and 
.I GKS 
can produce more sophisticated types of charts, but require you
to call functions from a library of routines in a C program.
Information on
.I CChart
and 
.I GKS
can be found in their man pages.
.PP
.I ProChart
looks for data files in the directory you are in when you start
.I ProChart.
It is recommended that you keep all your 
.I ProChart
files in one directory, and always start
.I ProChart
from that directory.
.SH OPTIONS
.TP 8
.B \-i
When invoked with the
.B \-i
option, 
.I ProChart
brings you to the Set-up menu immediately, where you can set such things
as screen device and default editor.  
.SH NAVIGATING THE MENUS
There are a few basic things you should know before you use 
.I ProChart.
.PP
To move around the menus, use the arrow keys.  You will notice that in the
command line, the use of a <-- or Backspace is mentioned.  You can 
perform functions that require a Backspace key by using any one of the keys
Backspace, left arrow, or F12 (on a VSII or VS100).
.SH DATA FORMAT
Data files for 
.I ProChart
should be in the form of one or two columns of numbers.  If you use the 
two column method, the first column is taken as the x-coordinates,
and the second as the y-coordinates.  So the file
.br
.na
.nf
1 4
7 90
8 12
4 2
.fi
.ad
plots the points (1,4), (7,90), (8,12), and (4,2).  If you use the one
column method, that column is taken as the y-coordinates, and the x-coordinates
are assumed to be 1,2,3...  So the file
.br
.na
.nf
70
65
35
2
.fi
.ad
plots the points (1,70), (2,65), (3,35) and (4,2).
