I'm trying to plot a graph (xy-plot) in MATLAB GUI. I have coded an equation along with input boxes for user inputs (the variables). So after the user input the many variables the program will calculate the answers. I have time 1 and time 2 as a range for the plot in the x-drection. Now I want to code it so it will plot all the points between time 1 and time 2.
What is the best way to go about this in GUI?

Please delete your previous question since this duplicate it's better phrased.

Oleg already gave you all the clues you need
T1=1;T2=10;NPoints=5;
u=10;v=20;w=1; %some inputs to your formula
t=linspace(T1,T2,NPoints);
c=u*t+v*(t/10)+w*t.^2; %your concentration formula, I made it up
plot(t,c,'*') %just the points
%plot(t,c) %line joining the points
%plot(t,c,'r*');hold on;plot(t,c); hold off %points and line

Let's say you have these two ranges:
time1 = now-9;
time2 = now;
% And you want to create 100 equispaced points on the range [time1 time2]
x = linspace(time1,time2,100);
y = f(x);
where f() is the equation you have coded, then plot:
plot(x,y)
If you don't what a specific function does, use the help or type in the command window:
doc functionName

I don't know how to word this but I'm trying to plot concentration to time, which is my output as a range in the y-direction.
C(x,y,z,t) etc.
t (time) is a function of C. When I input 2 values for t, I wrote the code so it would display 2 output for the C range. So if I input T1=1 and T2=10 I will get C1=X and C2=Y. I want to plot this two ranges with a set amount of points.
