## How do you make a vertical line in Matlab?

xline( x ) creates a vertical line at one or more x-coordinates in the current axes. For example, xline(2) creates a line at x=2 . xline( x , LineSpec ) specifies the line style, the line color, or both.

## How do I add a horizontal line in Matlab?

yline( y ) creates a horizontal line at one or more y-coordinates in the current axes. For example, yline(2) creates a line at y=2 . yline( y , LineSpec ) specifies the line style, the line color, or both.

**How do you plot a vertical line?**

To graph a vertical line that goes through a given point, first plot that point. Then draw a straight line up and down that goes through the point, and you’re done!

### How do you plot a line in Matlab?

Create a 2-D line plot and specify the line style, line color, and marker type. Add markers to a line plot to distinguish multiple lines or to highlight particular data points. Create a plot with confidence bounds using the fill function to draw the confidence bounds and the plot function to draw the data points.

### How do I draw a vertical line in Matplotlib?

Plot a Vertical line in Matplotlib

- x: Position on X axis to plot the line, It accepts integers.
- xmin and xmax: scalar, optional, default: 0/1. It plots the line in the given range.
- color: color for the line, It accepts a string. eg ‘r’ or ‘b’ .
- linestyle: Specifies the type of line, It accepts a string. eg ‘-‘, ‘–’, ‘-.

**What does undefined function mean in Matlab?**

Undefined function or variable ‘x’. These errors usually indicate that MATLAB cannot find a particular variable or MATLAB program file in the current directory or on the search path.

## How do you graph horizontal and vertical lines?

We learned:

- Horizontal lines go side to side and have a slope of 0.
- Vertical lines go up and down and have a slope that is undefined.
- Graphs of horizontal lines are parallel to the x-axis.
- Graphs of vertical lines are parallel to the y-axis.

## How do you draw a line plot?

To create a line plot, first create a number line that includes all the values in the data set. Next, place an X (or dot) above each data value on the number line. If a value occurs more than once in a data set, place an Xs over that number for each time it occurs.

**How do you plot a discrete time signal in Matlab?**

A discrete time signal just means sampling your continuous signal at discrete time intervals. The simplest way this can be done is by increasing your step in n. n = [-5:0.25:5]; y = 5*cos(pi*(n/2)-(pi/2));
