To create a horizontal line, we can use the Matlab built-in function yline(), which plots a horizontal line with a constant vertical value. Plot a Horizontal Line Using the yline() Function in MATLAB See other Linux Hint articles for more tips and information.This tutorial will discuss creating a horizontal line using the yline() function in Matlab. We hope you found this MATLAB article helpful. #XLINE MATLAB HOW TO#We have also included practical examples with image code snippets, showing how to set the style of the vertical lines and how to add text labels to them. We have described each of the input arguments in detail so that you can fully master this function. In this article, we showed you how to create and draw a vertical line on a graph using the MATLAB function xline(). In cases where multiple lines of labels need to be created, we must first create a cell array of character vectors with each of these labels in the appropriate order and send this array to the “label” input of the xline() function as in the following example. Next, we will see how the input arguments of the xline() function should be sent to create lines with text labels. We will now see an example of how we create a solid continuous blue line with the label “LinuxHint”. These labels are sent as character strings at the time of the function call in the “label” input of xline(). In this example, we show you how to add text labels to the vertical lines we create with the xline() function. How to Add Text Labels to the Vertical Lines of a Plot with MATLAB’s xline() Function The following figure shows how the line style and line color attributes can be specified with the LinSpec input of the MATLAB function xline(). To do this, we send the following string in the “LineSpec” input to set these attributes: Now, we use the “LineSpec” input to create a vertical line of the dash-dot line type in red color on the same graph we created in the previous example, this time at coordinate 0.2 of the x-axis. Next, we will see the color options offered by the xline() function. 'linetype color' = '- g' = Dashed line greenīelow is a table of the different line types and color options for the LineSpec. The syntax of the “LineSpec” input for selecting the line style and color is as follows: In this example, we will see how to select these attributes. When we draw vertical lines with xline(), we have the option to specify the type and color of that line. How to Set the Color Style and Linetype Using the LinSpec Input of the MATLAB Function xline() Next, we will see an example where we send a coordinate vector to draw10 equidistant vertical lines on a graph. So, it is possible to draw multiple lines by sending to “x” a vector with the coordinates of the multiple lines you want to draw. The input “x” to the MATLAB function xline() accepts scalars and vectors. How to Create Multiple Vertical Lines with MATLAB xline() Function In the following figure we see the line drawn from the x-axis: With these functions, we have created the following empty graph: Thus, the line drawn by xline() will be continuous and black. In this example, we use only the “x” input argument, so the line style parameters take the default values. In this case, in the middle of the axis, we enter in “x ” the value 0.5. To do this, we call the function xline() sending in “x” the coordinate of the x-axis on which we want to draw the line. Now, we will draw a vertical line on this axis. For this, we will first create an empty axis and enable the grid with the following functions: In this example, we will show you the simplest way to create a vertical line with MATLAB’s xline() function. How to Create a Vertical Line with the xline() Function in MATLAB This input accepts strings and cell arrays of character vectors. Labels: enters the text labels we want to add to the vertical line. The data type that LineSpec accepts is a character vector or string scalar. LineSpec: specifies the style and color attributes of the line. This input accepts scalars and vectors to specify the coordinates. X: Specifies the coordinate of the “x” axis from which to draw the vertical line. Next, we will look at each input argument for this function and explain the function each of them performs. It also provides the ability to place text labels and specify the format and attributes of the line color, width, linetype, etc. The MATLAB function xline() creates and draws vertical lines at a specified point on the x-axis of a graph.
