Using Matlab, I am trying to add multiple shaded regions to a plot of some data points. MATLAB creates a pseudocolor plot using each set of four adjacent points in C to define a surface rectangle (i. You can also provide labels for the x-axis using xlabel() and for the y-axis using ylable(). It's certainly not as straightforward so I recommend you just save the handles to the colors of the lines you drew, if you plan to detect them later. Experiments with MATLAB. Chances that you'll have to regenerate the figures at some point (because you decide to change one step somewhere in your analysis pipeline, say), and by scripting the plots as much as possible you can replace your pdfs with an updated one with just one….

The color order controls the set of colors that MATLAB uses for plotting multiple data series within an axes. Compared to PLOT, it is a hassle-free-plotter. I have a problem due to plotting auto-correlation. Control the colors, line styles, and markers used for plotting by setting properties on the axes and line objects. When hold is set to on, MATLAB does not reset the current gure and any further plots are drawn in the current gure. imshow(, cmap=cm.
