Hi, I am trying to create a pressure vs volume graph using Labview for data acquisition and importing the data to Matlab.
I was able to import the data to Matlab, but my graph looks like a sin wave that keeps oscillating. I am trying to calculate the area under the curve using the trapz function, but I would like to create a graph with only one curve representing the average of all the curves.
I thought of averaging the corresponding "y" points, but every cycle on the graph has a different amount of points so it is not possible to create a simple average program using Matlab. Also, I have used the cftool function, but it does not help me with creating just one graph. Can anyone please give some advice or any tips that can help me calculate the average curve of a set of curves?

Here is a set of data:
x = [5.1373 5.1473 5.1573 5.1673 5.1773 5.1873 5.1973 5.2073]
y = [17.6690 31.3300 43.8985 51.3575 53.8226 51.1592 40.9826 22.4972 6.3214 8.8891 29.2098 47.2177 53.7129]
where x is time in seconds and y is volume.
