how to switch the values of a variable

I have a project where the mass of an object is 1,2,3,5,and 7 and the value of m will be used to plot a graph. I cannot figure out how to make the code run where the first curve on the graph is when m=1 and the second curve on the graph shows where m=2....up until the last curve where m=7. In need all 5 curves to be plotted. I tried using the for loop but i dont know if that is correct. there is no error code, but only the m=7 curve is showing up.
This is what i have so far for the array and loop
array=[1 2 3 5 7];
for i=1:5
m = array(i);
disp (m)
end

I guess boldly:
This is probably your current code:
figure(1),clf(1)%don't forget clf during debuggin
array=[1 2 3 5 7];
x=linspace(0,3*pi,1000);
for i=1:5
m=array(i);
y=m*sin(x*m);%generate random y
plot(x,y)
end
In which case the issue is that plot replaces the previous contents of your axes, just as the NextPlot property tells it to. You can easily modify this by including hold on:
figure(1),clf(1)%don't forget clf during debuggin
array=[1 2 3 5 7];
x=linspace(0,3*pi,1000);
for i=1:5
m=array(i);
y=m*sin(x*m);%generate random y
hold on
plot(x,y)
hold off
end

You should put the call to bode inside your loop. I lack the toolboxes to test it for you, but it should either work as expected with hold on, or you should be able to extract the x and y data that forms the bode plot and use plot to create your intended result.
