Adding points onto graph with only X values

I filtered a graph and then used the findpeaks function to get the x values for the peaks. However when I filtered my graph the y-values changed from 700 to 1500 range to a -400 to 400 range. The x values are the correct, however I am not sure how to use text() to label points on the unfiltered data, or if there was another function I could use.
Thanks

Hey,
This function will help you to perform the required task. Once you have obtained the x and y coordinates of the peak. You can use the function as follows:
If x coordinate of the peak is 5 and y is 4 and the text you want to print is 'Peak'
text(5,4,'Peak');
