After you create a plot in Matlab, you might need to modify the characteristics of the figure. While many options can be specified during the initial plot command, they can easily be modified later as well using plot handles, and the useful functions of ‘findobj’,'get’ and ‘set’. If you are unclear on some of these commands, or need a refreshers, take a look at our tutorial on plotting .
One of the most common questions for Matlab users is how to plot data on a date axis. Many times, an analyst will initially use Excel, but then decide that he or she wants more analytical capabilities or plotting options. Excel has an easy way to plot data on a date axis, but to use a date axis in Matlab requires familiarity with a few functions. Don’t worry, using Matlab for this task is not that hard and, like most of Matlab’s functions, allows a considerable degree of versatility.
