You can make an Excel scatter plot assigning one of the variables in each record to the x-coordinate and one to the y-coordinate on a standard graph axis.

While Excel includes a legend automatically when you create the scatter plot, there are a number of ways to delete it; if your legend is missing you can get it back through the "Layout" tab.

Create scatter plots with trendlines to visually assess the relationship between variables. You can do this by selecting your data and choosing Insert > Scatter and then adding a trendline.
