Hi everybody, i'm trying to make the folowing script for grahp 7 points, but i do not understand why only represent only one point of the seven that i should draw.
hold on
grid on
n=0;
k=1;
step=1;
for i=7
y=con1+step;
x=1+step;
plot(x, y, '*');
k=k+1;
end
This are the 7 points
con1 =4.3e10
con2 =1.16e10
con3 =5.44e9
con4 =3.15e9
con5 =1.98e9
con6 =1.4e9
con7 =1.05e9
Can anyone help me to structure it better the code?. Thanks in advance

con = [4.3e10 ; 1.16e10;5.44e9;3.15e9;1.98e9;1.4e9;1.05e9 ] ;
hold on
grid on
n=0;
k=1;
step=1;
for i=1:7
y=con(i)+step;
x=1+step;
plot(x, y, '*');
k=k+1;
end

Use hold on after plot command inside the loop...using hold on points are plotted on the same figure. If not every time new figure opens.

Your for loop doesn't change anything so you just plot the same point every time. Neither con1 nor step changes so neither do x or y.
Did you mean to update step using 'i' or something like that? Or do you want con1 upto con7? In which case store them in a single array instead and access as
con(i)
rather than
con1

Well, of course you have to define con as an array containing all your values instead of the 7 variables you currently have as con1 to con7.
