Here we discuss an introduction to Matlab Plot Colors, along with color code table and respective examples. 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. MATLAB can be used to plot our data for visualizing and intuitively understanding it. Observe in the output that we have obtained a scatter plot of red color, as passed by us in the input argument. See other Linux Hint articles for more tips and information.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) We hope you found this MATLAB article helpful. We also show you some practical examples with different functions where we add code snippets and images to show you the many ways to use these inputs. In this MATLAB article, we have seen how to implement the LinSpec and LineWidth inputs to customize the styles and strokes on the lines of our graphs. These input arguments are part of all the graph functions this programming language offers, and it is a great advantage to know them. So, the string we need to send in this input would be the following: All of these parameters can be found in the LinSpec input argument. In this case, it is a black dashed line that we have added asterisks. In this example, we will see how to add markers to the graph we draw with the plot() function. Below, you can see the table with the individual mark options and the corresponding character: The type of mark is represented by a character and can be done only in LinSpec or with another that represents the line style or color. In addition to plotting the data, the plot function can add markers to the data using the LinSpec input instrument. How To Add Coordinate Marks With the LinSpec Input of the MATLAB Plot Function The following is the syntax of these inputs in the plot function: This is done by typing “LineWidth” and identifying the value in width. When we create plots or add graphs to them in MATLAB, we cannot only select the line color and style but also specify the width. How To Set the LineWidth’ of a Plot in MATLAB Plot The following table shows these four styles with their display characters: By default, the specified line will be continuous in the graph unless specified by the programmer. Line style strings are - for solid, - for. MATLAB provides four types of lines for graphing. Specifying Line Styles and Colors Color strings are c, m, y, r, g, b, w, and k. How To Set the Style of a Line in a MATLAB Plot We will create two lines, a solid red line and a green dashed line.Īs we can see in the following picture, the cosine “s” of “x” is shown as a solid red line, while the sine line is a green dashed line: This time, we will also determine the cosine of “x” in “c” and graph it. To do this, we will use the following code, which is identical to the previous example. Now, we will see how you can distinguish multiple variables in a chart by giving each a different line style. How To Plot Multiple Lines Each With Different Styles With the Input “LinSpec” To do this, we will use the LinSpec input to specify the selected color with the character it represents as shown in the following image:Īs we see in the following image, plot() draws the cosine of “x” with a green line, and the style and width of the plot have been given default values: In this example, we will use the plot function to plot a green sine wave. In the following table, we see the corresponding character for each color. Next, we see the syntax of the plot() function, which uses the LinSpec input to select the green color in the line that maps “y”. The default colors of “ColorOrder” are each represented by a character. These seven colors are part of the “ColorOrder” set, but users can customize their colors using the RGB scalars. MATLAB provides seven predefined colors for the color style, which it automatically assigns if the user does not define them. How To Set the Color of the Line in MATLAB Plot LinSpec is a string of characters that specifies the line style and color using representative characters in the following order: It is also used in functions for drawing arbitrary figures or reference lines, such as xline() or hline(). This line style constructs with the inputs “LinSpec” and “LineWidth”. These are the variables that control the style of the lines. Next, let us look at the syntax for this graph function, with the input arguments “LineSpec” and “LineWidth” shown in green. The most commonly used tool is the plot() function. MATLAB has an extensive library of tools that allow you to plot this data in 2D or multidimensional form. Graphs are the end product when we analyze variables or mathematical functions.
