Help needed in Subplot in Matlab

Hi,

I am new to Matlab and facing few issues in the following code:

1) I need to plot the graphs with varying the values of G. #1 for G=1.4, Molecular_Weight=28.97 ; #2 G=1., Molecular_Weight=28 ; #3 G=1.4 Molecular_Weight = 1.66 Can you please let me know the simplest way to do it, so I get the results in the same plot.

2) The current spacing between the plots is too less, what can I do to increase the spacings.

Thank you in advance! Your help would mean a lot to me.

The line figure you've entered before subplot(3,2,5) is used to open a new figure window.

figure
subplot(3,2,5)

Just comment or remove the line figure to solve your problem.

Cheers!

Thank you Jithin for helping me out. Can you please let me know how should I get the plot by variying G, and MW. Thanks!

Create two arrays/lists. G and MW, assign them as follows

G=[1.4,1,1.4]
MW = [28.97,28,1.66]

Then iterate through the length of one of the arrays

for i=1:numel(G)
disp(G(i))
end

You can use G(i) and MW(i) for accessing the 3 elements of the lists. Replace the G and MW in your code with these.

Finally to have multiple plots in a single plot use

plot(x,y)
subplot(3,2,4)
hold on

This must be done for each plots

And at the end of the iterator which iterates through the values in the array G and MW. Use

hold off

Hope this helps. Cheers

Hi Jithin,

Yes, that was one of my questions, and it worked well. Now, I have got five subplots in a single window.

On all the five subplots, now I want to see the effect of changing the G and Mol. Weight values (total three cases i.e. #1 for G=1.4, Molecular_Weight=28.97 ; #2 G=1., Molecular_Weight=28 ; #3 G=1.4 Molecular_Weight = 1.66). Can you please let me know how should I do that, so I get the plot for all the three cases in a single window (the same five subplots)? I look forward to your reply. Thanks!

Here's the best resource I could find for the spacing problem

I've edited my reply after reading your question. Upvote if anything helps.

I highly recommend completing the MATLAB Onramp course available for free. Have a great day.
