Here we discuss an introduction to Matlab Plot Colors, along with color code table and respective examples. This command takes RGB colors, color names. There could be instances when we have to plot multiple functions in a single plot, in such cases, colors become very handy to differentiate between different functions. Starting in R2019b there is a new colororder command that you can use to change the colors of new and existing lines. MATLAB can be used to plot our data for visualizing and intuitively understanding it. Creating a plot that uses differing line. Observe in the output that we have obtained a scatter plot of red color, as passed by us in the input argument. Whenever you create a plot in MATLAB, you need to identify the sources of information using more than just the lines. 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. c lines returns the lines colormap as a three-column array with the same number of rows as the colormap for the current figure. You can learn more about this topic at matwork.Observe in the code that we have passed pre-defined color code for red as an argument (Please refer to the table at the end of the article for pre-defined color codes) 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. Use the following code to try it out x = -pi:pi/10:pi I have multiple lines to plot but by defualt they are different color, how to change the color to uniform color I tried to do this but failed (see below). The axes are counted along the top row of the Figure window, then the second row, etc. Ill modify your example as follows: h plot(ydep, xvar. If you really need the two-color dashes, it might help to specify why. 'MarkerSize',10) should give you plenty of ideas for variation. Specifically, this example: plot (x,y,'-rs','LineWidth',2. H = subplot(m,n,p), or subplot(mnp), breaks the Figure window into an m-by-n matrix of small axes, selects the p-th axes for the current plot, and returns the axes handle. Matlab provides colormaps which can be scaled to the size of your data set, which is very handy here. Along those lines, take a look at MathWorks' documentation on 2-D line plots. What we really are doing is making a function that will me a series of lines, each with a different color. This is actually stretchig the truth a little since lines have exactly one color in MATLAB. Subplot helps have plots side by side on the same sheet. Instead of making a line with different colored markers in MATLAB, we will be making a multi-color line in MATLAB. ![]() Plot(x,y2,'b','LineWidth',2) Matlab subplot Multicolored lines are a single line created using a color map, which could be a default or custom color map to emphasize trends within that single line. One of the many ways to plot multiple functions on the same plot is to use hold on or insert the corresponding equations in the plot code. The Graph Plotting multiple graphs on the same plot Here is another example which you can learn a lot from Here is how to change the thickness of the line of your plot in Matlab point o circle x x-mark + plus * star s square d diamond v triangle (down) ^ triangle (up) triangle (right) p pentagram h hexagram - dashed. ( You can get that information with help plot) ![]() Here is the code you can use to change the line style. Let’s go ahead a plot the following code x=-100:0.5:100 The MarkerEdgeColor property controls the outline color, and the MarkerFaceColor controls the fill color. Here are the RGB triplets and hexadecimal color codes for the default colors MATLAB uses in many types of plots. Just like it is to change the color of your plot in Matlab, the same goes for changing the line style, increasing the thickness of the line or some other aspect of it Specify the marker size as 75 points, and use name-value arguments to specify the marker outline and fill colors. 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. You must surely have grasped how to add the color code to get your graph to the wanted color, and notice at the beginning of this post the different color and code you can make use of while using this technique Matlab plotting line style 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. Let’s twist the code a little to change the plot color
