Radix User's Manual
BPS Business Graphics will use the same device driver until you
install another one.
Now, when you have your points loaded and are ready to
print a graph, use the following commands:
DRAW (Plus the appropriate arguments)
SET OUTPUT UNIT PARALLEL
WRITE SCREEN (Plus the appropriate device name)
Your graph will first be displayed on the screen and then
printed on Radix.
There are several ways to vary the way graphs are printed.
Obviously you can use the many features of BPS Business Graph-
ics to add elements to your graph. But you can also change the
quality of the way the graph is printed.
One way to change the printing is to use the SET FILL CYCLE
command. This will change the pattern of each element of the
graph as it is drawn. In a pie graph it will change the pattern in
each section of the graph.
Another way to improve the quality of the printed graph is to
use the DET DEVICE CONSOLE HIBW command. This com-
mand tells the program that you have a high resolution monitor.
BPS Business Graphics then plots in its highest quality, which
may not look very good on your screen if you don't have a high
resolution monitor. But when the image is printed it will be in the
highest possible quality.
Making pie graphs round
BPS Business Graphics uses what it calls a rounding factor to
make pie graphs round. Many output devices produce oval pie
graphs because their aspect ratios don't match. The aspect ratio of
an object is the ratio of its height to its width. The rounding factor
is the third argument to the DRAW PIE command, so with a
rounding factor of
1,
the command looks like this: DRAW PIE
O,O,l.
-
The following table shows the rounding factors to use with
the different console modes.
BPS Business Graphics can create many types of graphs, and
we have just touched the surface of its capabilities, but with these
hints you should be able to get started printing graphs quickly
