Unwanted items showing up in plot legend

Hello, I am trying to add a legend for a graph that has several scatterplots with lines of best fit. I am trying to only display the scatterplot items on the legend, but for some reason it's adding in a bunch of random items. I assume they have to do with the lsline command I used, but I don't know how to get rid of them. Any help would be appreciated.

Note that you only need one lsline call, because lsline finds all scatter plots in the current axes and draws lines for each of them. So draw all the scatter and lsline once.

Record the handle of all scatter() calls in an array. Pass that array to legend()
