Re: Graphing Need Help
Use statistics. Press STAT, F2 EDIT, and press ENTER twice. You can now enter
some values. When you are done, press 2ND-F3 DRAW, and you can plot the
points. Or, first, press CALC, ENTER twice, and then select a type of
regression that you think is appropriate for your data. Then, in DRAW, you can
graph a curve based on your points. You will probably need to setup the
viewing window by pressing GRAPH, F2 RANGE.

I am trying to figure out a way to plot antenna beamwidth patterns on
my TI-85... I'm a math moron, and I haven't got all this calculator
stuff figured out... Here's an analogy of what I want to do, can
anybody help...
Let's say the x dimension on my calculator is going to represent time,
the y is going to represent temperature. I want the calculator to plot
a graph in that at X time (X is going to be incremented automatically
in my program, let's say for this example every 5 mins.) So every five
minutes I have taken a temperature measurement, written them down, and
now I want to put the data into my calculator. Since X is incremented
every 5 mins, all I have to do is enter the temperature and I should
get a graph plotting temperatures over a whole day (every five mins)
Right now, this is what my program looks like...
for(X,0,288,5 time (X) starts at 0, goes to 288, increments by 5
Prompt Temp
PtOn(X,Temp
It's simple, it works, but it only puts dots on the display, I want
nice curves and sine looking stuff. So that's my problem.. I know it's
probably the simplist thing to do in the world, but I'm an idiot
(Humor me) :)
Thanks in advance.
