And 6 dashed lines colored using the default color order. After that we display the result by using Matlab display function. The "Color" property of a line stores the RGB value of that line, whether it is a default or custom-set value. An RGB triplet is a three-element row vector whose elements specify the intensities of the red, green, and blue components of the color. I didn't specify the colors. Many plotting functions have an input argument such as c or colorspec for customizing the color. But I often want to emphasize the interrelations among related lines. Modifiers remain in effect until the end of the text. For example, the first eight lines plotted use the different colors defined by ColorOrder with the first line style. What is MATLAB Colormap? Humans are not equally perceptive to all colors. This form also allows you to specify the patch using the Faces and Vertices properties instead of x -, y -, and z -coordinates. color default defaultfigurecolor feature graphics handle MATLAB undocumented. The arrowhead display is on by default, but we can turn it off using the ShowArrowHead property. Can only be used with truecolor images. Default colour and line style order. This leads to an efficient use of color resources (which are limited on systems capable of displaying 256 or less colors) and extends the number of figure windows that can simultaneously display correct colors.
