FOR loop merge plots

I have a Simulink model which has user-defined library blocks in it. The values for the variables inside these library blocks are fetched from an ‘m’ script. Basically, I am running the m script to load all the library blocks, then the Model and then run the Simulink model to plot few results. But, I am looking for running the model twice with different values for few variables. Below is the syntax

 For count = 1:2;
 Load_syntax(‘library_block’)

 model = 'model_name';
 load_system(model)
 sim(model)

 plot()
 plotyy()
 plot()
 .
 .
 & 6 to 8 plots 

 Variable_name = new value;
 end

I am not sure how to merge the plots with the new values over the previous plots, to analyse the results clearly (also plot using a different color). Also, please let me know if we have any other way to achieve this. Please help. Thanks in advance

Since you have multiple plots, you can use figure() to specify which window to plot on. Use hold on if you want to plot the curves together. plot() command has a color option.

figure(1);plot(1:10,'r');

figure(1);hold on; plot(10:-1:1,'g');

Thanks for the answer. with figure(#) now I am able to merge plots together. But, not sure how the color option works with the loop function. It plots with the same color, the second time also. So it is difficult to distinguish between the two.

Is there a way to plot the graph with a different color? I have 2 kinds of graphs. Plotyy and a graph which is already merged(as shown below). When it loops, it plots with the same color. Please help.

 plot(torque,'r')
 hold on
 plot(speed,'g')

 plotyy()
 hold on

I tried by removing the color code and but it takes the same default color code, twice. So, not sure how to handle this.
