Shifting horizontal axis labels on a Scatter Plot

Kind of an unusual problem I've been trying to solve for a while -- I have some data that is plotted on a scatter plot, and I would like to have the horizontal axis labels as 1000, 1500, 2000, 2500, 3000, and 3500, with minor tick marks every 100. Problem is, I need to include data from 600-3500. I would need to begin my labeling not at my minimum value, but at 1000. I have generated some sample data and will post the example sheet here. Any ideas are appreciated, note that I only need the plot output, the sheet "cleanliness" is not an issue here.

You're a lifesaver! Thank you!
