In this case, where I’m using multiple lines within the legend, it I am plotting several data sets on one figure and want a legend to distinguish which line is which, the problem is MATLAB won't display the correct color of the line on the plot in the legend (see Imgur, the 4th item in the legend to be represented by the red line on the plot). This has created labels for the axes, given the plot a title, and put a plot legend in the lower right hand corner (thus the 'SouthEast' string). Data visualization is very powerful in getting the look and feel of the data in just one glance. Matplotlib supports all kind of subplots including 2x1 vertical, 2x1 horizontal or a 2x2 grid. To create a scatter plot with a legend one may use a loop and create one scatter plot per item to appear in the legend and set the label accordingly. The MATLAB figure window displays plots.
