user_number=20;
test_data=ones(1,user_number);
plot(1:user_number,test_data);

And yes, you definitely find the straight line (horizontal), because all the values ​​of the y-axis are the same here. To load the data from text file, you can user load function with complete filename.

Thanks for your answer, but I have those ones in text file, how to import it in your code?

[Brave A]

I don't want them in straight line (horizontal). Any suggestions to represent them?

[KALYAN ACHARJYA]

load('file_test.txt');
%  txt   ^ sample file name
bar(file_test);

Since all the values are the same, the height of all the bars will be the same.

or

load('file_test.txt');
plot(file_test,'*');

it covers all the figure. How to reduce the size?

[Brave A]

What I need each '1' in y axis represent user number in x axis . so I need the line increases.

something like this.

[KALYAN ACHARJYA]

To get such plot, the text data must be 1,2,3...or increment with any order

user_number=300;
test_data=1:300;
plot(1:user_number,test_data);

[Brave A]

no, not this is what I want. I have the text file which contains 276 ones. Is there any way to relate them with x axes values so I can get desired plot?

[Rik]

So you start of with this:

data=ones(276,1);

How do you want to determine x and y values? If you have to explain it in words?

[Brave A]

It did not works. Is there any way to relate them with x axes values so I can get desired plot?

[Rik]

You are not explaining how you are converting your data to a plot. Explain in words how you would find x and y points from your list of ones. I have no idea why you would not get a straight horizontal line. If you don't explain that, I can't help you.

[Brave A]

So I have 300 users and only 276 from got selected as ones and the rest is 0 . So I need to represent this selection in y-axis and relate each one to the user number select. Thanks in advance!

[KALYAN ACHARJYA]

For example, lets say, the user number is 5

user_num= [1 2 3 4 5];
select_da=[0 0 1 1 1]; % Just random example 
plot(user_num,select_da)

[Brave A]

this is not what I want .

[Rik]

Can you share an example file? I suspect cumsum will do the trick for you, but I'm not sure, because you refuse to explain it with more words.

[Brave A]

Sure! Here is the dataset contains 1 for selected users and 0 for nonselected. Thanks in advance!

[Brave A]

I need to represent it in this way of containing 0 and 1 or only ones. Just need the reader to understand what is my results from figure.

[Rik]

Judging from this data you can use cumsum to make the plot you described.

[Brave A]

I have another data set same like this how to plot with cumsum? because it's combiened then in one line.

[Brave A]

I think I got what I need ! Big thanks both of you.
