Plotting data with Octave

Plotting data with Octave

In this tutorial, we will learn detailed steps to plot data using an Octave script.

Sample function

We can choose any function. Let’s choose a simple function y defined as:

y= 1/(x^2 + 1);

Generate x vector with some sample points from 0 to 10.

x=linspace(0,10,100);

Calculate y vector.

y= 1./(x.^2 + 1) ;

Steps to create Script

Launch Octave.

File >> New >> New Script

File >> Save File to save the file.

Plot command

 

%Plotting data using OCtave
 x=linspace(0,10,100);

 y= 1./(x.^2 + 1) ;

 %Plot graph

 figure

 %plot command

 plot(x,y,'ro','MarkerSize',30)

 xlabel('x')

 ylabel('y')

 title('Sample Plot');
