How to combine two figures into one figure?

Hi,

I have two figures which each one is a 1x3 subplot now and I want to combine these two figures into one figure for some use.

Originally, i want to use a 2x3 subplot to present the result but the 2x3 subplot will make the fugure trend is not so clear (each subplot is to flat).

Finally, I break up the 2x3 subplot into two 1x3 subplots and get the clear figure trend.

However, since these two 1x3 subplots are under the same topic and I want to combine it into one figure that keeps the clear figure trend but could not achieve this goal.

Does anyone can tell me how to handle it?

Below is my code:

clc; clear

a = xlsread('just test' , 'linechart', 'C5:J154'); 
b = xlsread('just test' , 'linechart', 'N5:U154'); 
c = xlsread('just test' , 'linechart', 'Y5:AF154');  
for i = 1:1:25

Two 1x3 subplot are like below:

Now I want to keep its shape and combine these two 1x3 subplot into one figure. How can I do it?

Any help would be much appreciated. Thanks

Answer 1

[Walter Roberson]

subplot(2,6,n) instead of subplot(2,3,n), using subplot numbers 1, 2, 3 for the first plot, and 7, 8, 9 for the second plot, and not plotting the others.

You are happy with a 1:1/3 aspect ratio . When you have to go to 1/2 height to get two rows in, the to keep the aspect ratio that would be 1/2:1/6 , leading to subplot(2,6,*)

[Chao-Zhen Liu]

Hi Walter,

I got your idea! Thanks!

By keeing the 1:1/3 aspect ratio, each subplot would not be flat now but there is another problem that the plot is too narrow like below：

and the right hand side of figure is blank.

How can I cut the blank and scale the left hand side without changing the aspect ratio?

Thanks for your advice!

[Walter Roberson]

Without changing the aspect ratio, all you could do is move the subplots further apart from each other.

You could experiment with (2,5,*) plots 1, 2, 3, 6, 7, 8, or with (2,4,*) plots 1, 2, 3, 5, 6, 7 to see if those are acceptable.

[Chao-Zhen Liu]

Hi Walter,

Oh, thanks, I will try it after a while.

Much appreciated!
