As a side-note, this isn't even documented in the Chart line appearance and behavior part of MATLAB's. 0 0 0 for black, then change the alpha (transparency) between 0 (invisible) and 1 (completely visible).
#Color lines matlab series#
We ordinarily use our peaks function to demo surf or contour plots, but it is also useful to view peaks as a series of lines. You can use the RGB-alpha quadruplet: plot (x, y, 'Color', 0 0 0 0.3) The first three entries are your standard RGB-triplet, i.e. Singly even magic squares are the most complicated. I am especially fond of the copper colormap in these situations. Let's not forget our former best friend, jet. n 19 plot (magic (n), 'linewidth' ,2) title (sprintf ( 'magic (d)' ,n)) The color of these lines is obtained by cycling through the 'color order', which, by default, is these seven colors. If either x or y, or both are matrices, then line draws multiple lines. n = 'magic(%d)',n))īy the way, you are seeing three kinds of magic squares - when the order n is odd, when n is divisible by four, and when n is even but not divisable by four. When you plot a two dimensional array, you ordinarily get a bunch of lines, colored like this. line( x, y ) plots a line in the current axes using the data in vectors x and y. So, I set the color order to one obtained from our colormaps. Parulaīut I often want to emphasize the interrelations among related lines. The plotted line uses all colors in a given colormap in ascending order. If Y and Z are not given, a 2D plot of X over 1:length(X) is created. If Z is not given, a 2D plot of Y over X if created. This default color order is designed to distinguish distinct lines by well separated colors. H colormapline(X,Y,Z,C) Plot a line using a specified colormap If Z is given, a 3D plot with coordinates X, Y, Z is created. The color of these lines is obtained by cycling through the "color order", which, by default, is these seven colors. ColorSpec defines the color to use.When you plot a two dimensional array, you ordinarily get a bunch of lines, colored like this. The color of the marker or the edge color for filled markers (circle, square, diamond, pentagram, hexagram, and the four triangles). Make One Plot Different From Another Using Different Line Colors in MATLAB You can change the color of lines in the plot to make them different from one another in MATLAB. x rand (1,100) y rand (1,100) scatter (x,y,75, 'MarkerEdgeColor', 'b'. MATLAB uses the number to calculate indices into the ColorOrder and LineStyleOrder arrays. The MarkerEdgeColor property controls the outline color, and the MarkerFaceColor controls the fill color.
This section lists property names along with the type of values each accepts. Specify the marker size as 75 points, and use name-value arguments to specify the marker outline and fill colors. To change the default value of properties see Setting Default Property Values. Ill modify your example as follows: h plot(ydep, xvar. What we really are doing is making a function that will me a series of lines, each with a different color. Matlab provides colormaps which can be scaled to the size of your data set, which is very handy here. If you want more of your lines to be distinct in both color and line style, use the withcolor option and specify an equal number of colors and line styles. Each row in the array contains the red, green, and blue intensities for a specific color. If no figure exists, then the array contains 256 rows. This is actually stretchig the truth a little since lines have exactly one color in MATLAB. Description c lines returns the lines colormap as a three-column array with the same number of rows as the colormap for the current figure.
The intensities must be in the range 0, 1. An RGB triplet is three-element vector containing the intensities of the red, green, and blue components of a color. Line Properties (MATLAB Functions) MATLAB Function Reference The colors MATLAB selects come from the axes ColorOrder property, which contains a three-column matrix of colors specified as RGB triplets.
