Help creating graph from multiple data

Hi all,

I am having difficulties graphing some data that I have. I have included the excel file below if this helps. I want to graph two things against one another, but each of the two sets of data has five columns of information. The 'X' axis should be the DN from the K column, and the 'Y' axis should be the DN from the B column. I want to graph the data in terms of its relative abundance- the numbers of data points are given, as well as the percent of the total that this consists of. I ultimately want to do regression analysis on these two data sets, but I just want to start with creating a graph first. I know how to create a normal graph, but I'm pretty lost about how to do this. Any input at all would be appreciated. Thanks.

So far I have something that looks like the graph I've attached below. The first graph is what I have so far, with one set of values as the X axis and another as the Y axis. However, I can't figure out how to graph two sets of data on the same line without creating two lines. Ideally I would like to create a graph that looks like the second picture shown below. Thanks again. goodgraph.jpgbadtestgraph.jpg
