I have several area graphs in an Excel spreadsheet. I want all of those graphs to have exactly the same scale.

Each of the graphs have a measurement in meters on each of the axes. I want each of the axes to be exactly proportional to each other, so not like this:

But (roughly) like this (the image is squished, this is just a demonstration, I need Excel to do that for me):

Is this possible *without* either using an image editor, or just manually scaling the graphs "by eye"?

If it's relevant, my Excel version is 2013. Also, don't worry about the graphs being upside down, they're meant to be like that.
