# plotting triangular graphs

Hi I need help, i have to plot a triangular graph as part of a lab assignment and i don't know how gotoxy(??...)!
Can anyone help me!

Can you be more specyfic. I can't figure out you're problem. What did you mean with gotoxy(??...)?

Sorry it was very ambiguous, its a pascal program aswell i probably should have mentioned that(!), ok when when plotting a sin wave you have to input amplitude, frequency and phase as well as the number of points you want plotted end the program looks like this:

begin
for i : 0 to points-1 do
val := amp*sin(2*PIE*freq*i/points+ phase);
gotoxy(i+1, OFFSET - round(val));
write('*');
end;

obviously there's stuff left out like actually getting the freq, amp etc inputted but you get the idea, so i how do change that program to plot a triangular wave?
