Re: Graphing Software



More about True Basic. In my opinion students would benefit more from
programming their own grapha than by using prepared subroutines. It is
nearly the same as programming by hand. Student edition, for either Mac
or PC, costs only $20 (including the manual). And its only limitation
is the length of the code, no more than 200 lines.

one command to plot the horizontal line where you want
onother to plot the vertical line
and a short do loop for the segment-by-segment plotting.

The do loop my use the formula, read the x,y data from DATA lines or
read data from another file. You must "calibrate" your screen in real
units, such as meters or inches, if the coordinates are in these units.

oop, I see a typo, too late to correct.
