Representing data from File !

Hello Guys, I have a data in a file consists of two columns one for the arrival time and the other one for the Energy(ev).. I want to represent the data in the x-axes region so I will be able to estimate its function using kernel density function.. I am not sure how to represent the data in the x-axes though? I did once represent the data in the x-axes like a little dashes way and I used(repmat)but with this case I don't have any idea how to do so.. In this link there is an image and if you look at the x-axes you will see some dashes that are more in some area and less in another, thats exactly what I am looking for so I will be able to estimate its function later on..
Also, in my previously asked question you can see if you run it what I mean by "little dashes on the x-axes(red data))
Thank you all,

Go back to your previous post. I saw similar dash in the figure. The answer is right there. The command to draw it is line().
Sa=0:0.2:2; %if your original data is column vector, transpose it.
line(repmat(Sa,2,1),repmat([0;1],1,length(Sa)),'color','r' );
axis([0 2 0 10]);

@Susan, you need to go back to the basics of MATLAB or programming in general. The line() command draws a line from one point to another point. In this example, it draws from (0,0) to (0,1), from (1,0) to (1,1), from (2,0) to (2,1) etc. The height is all 1. If you want to change the height, you can change the number accordingly. If you can't understand and see this, you need to go back to the basics.

Do you want to represent the Energy or the arrival time in the X-axis? The small dashs at the bottom of the shown image represent just a binary signal versus time, e.g. the arrival times of detected signals. Therefore it is not clear, how you want the two data sets to be represented in a diagram. The small dashs with equal size simply do not match to your data.
