Hi chitta

only limit your range, what is the range you want to zoom?

For example:

x=1:10;

y=sin(x*pi);

plot(x,y);

//zoom

figure;

plot(x(1:5),y(1:50));

is this helpfull for you? If no tell me and i will tell you another way

Thanks for your reply. unfortunately it is not showing as i want. it is showing two graph. but i want both to be club in one graph. if you have any other way please let me know.

Hi Chitta, do you mean you want to have an enlargement inset inside the plot? If so I don't think Matlab can do this but you could always export both as PDFs and then use a tool like Inkscape to achieve the result you want. L

Hello Behera, I also encountered the same problem. I found a m function "magnify" which may also solve your problem. It's very easy to use.

1. Open a figure you wan to zoom.

2. Type "magnify" in commend window.

3. Move the cursor to the part you want to zoom, click left mouse button and hold. Now you can see the zoomed part of the figure.

4. Adjust the magnification by "+" and "-", and the size of PIP by "". Remember the left mouse button must be held in this period.

5. If the adjustment is done, release the left mouse button and click the right mouse button.

6. Finally, you have the zoomed part of the figure.

The sample figure is also in the attachment.

I hope this will help. Good luck!

Oh, sorry, I forget the m file.

Furthermore, there is a little mistake. The step 5 should be done with the left button pressed.

Good luck!

Dear Zheng

I have done as you told, but the sample and zoomed both figure are overlapped.

Is there any mistake in my process. How can I find the separate two figures as you shown in the sample figure.

Thanks

Hallo Sharma. You can move the PIP and modify it's property with the cursor in figure tool bar. It's very convenient.

Plot a figure and then use the following matlab function

Hello Arshad! Thank you for your answer. I find your function is more powerful than mine. Thanks again for your sharing!

U are most welcome Mr Zheng

Thanks a lot Ali! Its great!

It is really great work. I am a beginner in Matlab and confused about coding and Matlab' s functions. Therefore, I do not how I use it. Could you please explain how to implement Ali' s function into the following code.

figure;

s = sprintf('x_2=f(x_1)', char(176));

hold on;

rectangle('position',[-0.25 -0.25 0.50 0.50],'curvature',[0.01 0.01],'LineStyle',':','edgecolor','m')

ezplot('x^2',[-5,5,-5,5]);

ezplot('x^3',[-5,5,-5,5]);

ezplot('-x^2',[-5,5,-5,5]);

legend('f_1(x_1)=x_1^2','f_2(x_1)=x_1^3','f_3(x_1)=-x_1^2')

title('2D frame in (x_1,x_2) coordinate system')

xlabel('x_1')

ylabel(s)

hold off

@Cagdas Akalin

first of all it is not my function, I took it from Mathworks, but, I can help you for your case.

Just compile your matlab script and then without closing your figure, run that function. This will show a rectangular box on the figure, and you can move the box to see the zoomed view of the portion of the graph you want to see. 

Hi @ all. I got simpler, but more effective Matlab code for zoomed view in a figure. This script is written by "KYE TAYLOR", and I found it on the Mathworks website. Follow the link please. In case of any issue I can be contacted, especially the begginers

Thanks

I think the following matlab code solve the chittas' problem.

box on;hold on

plot(evrything you need,'LineWidth',4,'Color',[.2 .2 .2])

legend('every thing you want)')

xlabel('')

ylabel('')

axes('position',[0.25, .2, 0.25, 0.2]);

hold on;box on

plot(1:b,xn(1,1:b),'LineWidth',4,'Color',[.2 .2 .2])

ylim([-.5 .5]);

xlim([1 50]);

in aforesaid math code the position parameters should be adjusted and the ylim and xlim should be defined correctly

just use the matlab inbuilt 'zoom' and 'pan' functions after the plot line.

https://uk.mathworks.com/help/matlab/ref/zoom.html

how do you get a graphic part in Matlab?

ax1 = gca; ax2 = axes('Position',[.7 .7 .2 .2]);box on;grid on;

this will make a subplot in the right corner of your curve afterwards just copy and paste your figure in the new created subplot then use Matlab built in functions on your small figure.

pan on;zoom on;

thank you
