I am trying to essentially plot three things on a single 2-D graph. That is, say we have a matrix
p(m,n) = [1 2 4; 3 5 7; 6 7 9];
Let us now say that the indices m,n in p correspond to different parameters in an equation. Now my matrix p contains the solutions T to this particular equation when the parameters m and n take on values 1-3. My goal is to be able to plot m vs. T, but I want each element in p(1,:) to have a different color, say p(1,1)=red, p(1,2)=green, and p(1,3) = blue. For the next row, m = 2, I would like p(2,1)=red, … I would then like to be able to connect all of the red markers with a line, all of the green markers with a line, and all of the blue markers with a line. In this way, I would be able to see how the values of T change in my plot as m and n vary all within the same graph.
For starters, I can use a for-loop to produce vectors of all one value of the proper length, and store them in a matrix:
p = [1 2 4; 3 5 7; 6 7 9]; x = ones(1,3); for i = 1:1:3 vec = i*x; % Prints out a vector [i i i ...] for each i from 1 to 10
n(i,:) = vec; % Stores vectors in matrix (note i iteration index is necessary to define matrix)
end n % prints out entire matrix
plot(n(1,:),p(1,:),'*') hold on plot(n(2,:),p(2,:),'^') plot(n(3,:),p(3,:),'.')
I would now like to have each column in the matrix be a different color and connected by a line. Thus, for all of the values where n=1, there would be a line connecting them together. Does anyone have any suggestions by how I might accomplish this?
