What are line drawing functions in MATLAB?

line( x , y ) plots a line in the current axes using the data in vectors x and y . If either x or y , or both are matrices, then line draws multiple lines. Unlike the plot function, line adds the line to the current axes without deleting other graphics objects or resetting axes properties.

What are line specifiers in MATLAB?

How do you make a dashed 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. For example, xline([12 20 33],’–b’) creates three dashed blue lines.

What is line plot in MATLAB?

Line plots, log plots, and function plots. Line plots are a useful way to compare sets of data or track changes over time. You can plot the data in a 2-D or 3-D view using either a linear or a logarithmic scale. Also, you can plot expressions or functions over specific intervals.

How do you plot different lines in MATLAB?

Plot Multiple Lines By default, MATLAB clears the figure before each plotting command. Use the figure command to open a new figure window. You can plot multiple lines using the hold on command. Until you use hold off or close the window, all plots appear in the current figure window.
