how can I save the all graphs with different names at the same time?

I have excel file I want to plot the various column data against time column, then my question is how can I save the all graphs with different names at the same time?

Answer 1

Try with using of 'for' looping . every iteration of graph creation may give that different name .

I tried for loop but it is not working. so can you please explain me in brief?

[Heramb Gaikwad]

also I tried with while loop. But does not work.

Make a loop that loops over each figure, and save each figure. You can generate the filenames (or other info) during each loop.

This is covered very well in many posts in this forum, and also in the MATLAB wiki, including example code:

Dear Sir, Actually my problem is I have excel file. I have read this file by following program:

[inFileName,inPathName] = uigetfile('*.xls','Select the xls-file');
a=xlsread(inFileName);
b=a(2:1394,:);
c=b(:,7);
j=16;
while j<=33
d=b(:,j);
dd=smooth(d);
a1=plot(c,dd);

xlabel('time (min)'); % x-axis label
ylabel('velocity (m/s)'); % y-axis label
title('Graph of velocity Vs Time');
legend('zonal velocity m/s');
j=j+1;
end

Now, after one time execution of program one file is created; that file at the same time I want to save. then next time it will execute then second graph is created; that graph I want save with again different name and so on till the condition is not satisfied.

You can use print to save a figure, like this:

[inFileName,inPathName] = uigetfile('*.xls','Select the xls-file');
a = xlsread(inFileName);
b = a(2:1394,:);
c = b(:,7);
for k = 16:33
    d = b(:,k);
    dd = smooth(d);
    a1 = plot(c,dd);
    xlabel('time (min)');
    ylabel('velocity (m/s)');
    title('Graph of velocity Vs Time');
    legend('zonal velocity m/s');
    print(sprintf('ImageFileName_%d',k),'.png');
end

Read the print documentation for lists of the supported image formats, and other useful options.
