Continuous execution of vertical line for set of data

I'm new to Matlab

I want to plot a vertical line at specific values which I have stored in a variable, "HR"

For some data sets, there are several values within the variable and it would take a lot of time to plot a vertical line at each value.

Can someone help me write a code that continues to execute plotting this vertical line through the entire data set?

Example:

In the variable "HR" I have stored all of the values below. I want to plot a vertical line at each of these values. How would I go about writing a code or iterative loop to do this until it has plotted lines at each of these points and finished the data set?

"I want to plot a vertical line at each of these values. ". The array you provided is 1D array. You will get 1 line plot out of these array.

A=[0.340000000000000
0.980000000000000
4.65900000000000
5.24100000000000
38.8100000000000
39.4390000000000]
plot(A)

Are you trying to plot multiple line in the plot out of this data?

What is the dimension size of the array?

[Sam]

I have a 2D array. I have a plot already made to show my entire data set, but I saved these values as a different variable because I want to highlight them out of the entire plot by adding multiple vertical lines at these time points 0.34, 0.98, 4.659 etc. I'm setting a threshold so all of these values are above the threshold.

0.34000000000000 93.7500000000000

0.98000000000000 106.382978700000

4.65900000000000 103.092783500000

5.24100000000000 97.7198697100000

38.8100000000000 95.3900000000000

39.4390000000000 99.3377483400000

239.070000000000 95.0900000000000

If you can attach your code, and variables (in a mat file), it would help us to help you.

[Sam]

I attached the file below. I don't have any code written for this yet. I was just looking for advice on the loop part. The elevatedHR is the separate variable for the times above threshold. I included a sample plot to give you an idea.

[ANKUR KUMAR]

Hope this helps.

load('Sample.mat')
yy=data(:,2);
vert_lines=elevatedHR(:,2);
xx=1:length(yy);
plot(xx,yy)
hold on
for kk=1:length(vert_lines)
   index=find(yy==vert_lines(kk));
   for indices=1:length(index)
      plot(ones(1,2)*xx(index(indices)),[50 110],'r-') 
   end
end

[Sam]

Thank you so much Ankur. I appreciate your help. I'll try this.

It's not clear to me exactly what type of graphic you're trying to plot, but I think the stem and xline functions may be of use to you. Alternately, open the Plots tab on the Toolstrip. Click the small downward-pointing triangle in the Plots section of that tab and look for a thumbnail that appears similar to the type of plot you want to create. From there you can determine the specific plotting function used to create that type of plot (its name is below the thumbnail) and read its doc page to learn how to use it. You can even create the plot from the thumbnail if you have your data selected in the Workspace window.
