# MATLAB 2D Plot command

### Introduction

The basic plot function in MATLAB is the plot linear plot command. The simple plot command takes two vectors X and Y and plots them in 2D space.

plot(X,Y)

The plot command can plot in color and with different symbols.

### plot command

Let’s issue the plot command from the Command Window prompt. Create two vectors for the plot command.

```>> x = linspace(-pi,pi,100);
>> y = tan(sin(x)) - sin(tan(x));
>> plot(x,y)```

### Screenshot linspace creates a linearly spaced vector. For example,

linspace(low,high,N) created N points between low and high.

### Sample Script

Lets write a simple script to add title , labels to the graph.

```% Sample MATLAB Script to plot a function
% MATLAB Tutorials - www.TestingDocs.com

x = linspace(-pi,pi,100); % 100 linearly spaced points within [-pi,pi]
y = tan(sin(x)) - sin(tan(x)); % Plot function

plot(x,y);
xlabel('x-axis');
ylabel('y-axis');
title('MATLAB 2D Plot Demo - www.TestingDocs.com');```

Run the script.

Notice that the graph now has a title and x,y axis labels. Adding markers to the plot command.

‘MarkerFaceColor’,’k’,…
