In this tutorial, I have covered different types of plots by using examples and different functions [color |marker style| line spec]. It's a scatter plot - it's not like you have two different sets of data where you can plot each with a certain color against some independent x axis. MATLAB automatically selects a viewpoint that is determined by whether the plot is 2-D or 3-D: For 2-D plots, the default is azimuth = 0° and elevation = 90°. Instead of points being joined by line segments, here the points are represented individually with a dot, circle, or other shape. Go to the tutorial on creating regression lines to find out how to use a regression line with this scatter plot to calculate the concentrations of the two unknowns. If you specify a marker, but not a line style, MATLAB plots only the markers. For plots with many data points, it becomes visually crowded.
