I would like to integrate the area under the the curve and hope to chose the area manually. I have attached a sample figure. Thank you!

Can you attach a PNG screenshot? It's easier for us (no need to read it in with MATLAB, can see it here).

You can use ginput to click and select points from a figure window.
Once you've got the points, "integrating the area under the curve" is just a matter of adding the values and dividing by the space between values.

You could also use a slider and some buttons in an app to select the area of interest. See App attached.
