How to use axis function in Matlab

Usage of axis function in Matlab: 1. axis([xmin xmax ymin ymax]): This statement sets the range of the x-axis to xmin to xmax, and sets the range of the y-axis to ymin to ymax; 2. axis('equal'): This statement sets the ratio of the x-axis and the y-axis to be equal so that the shape drawn on the graph will not be stretched or compressed; 3. axis('off'): This statement turns off the coordinate axis ;4. axis('tight') and so on.

#In Matlab, the axis function is used to control the range and scale of the coordinate axis. Its usage is as follows:

1. axis([xmin xmax ymin ymax]): This statement sets the range of the x-axis to xmin to xmax, and sets the range of the y-axis to ymin to ymax.

Example:

x = 0:pi/100:2*pi;  
y = sin(x);  
plot(x,y);  
axis([0 2*pi -1 1]);

2. axis('equal'): This statement sets the scale of the x-axis and the y-axis to be equal so that the shape drawn on the graph will not be stretched. or compression.

Example:

x = 0:pi/100:2*pi;  
y = sin(x);  
plot(x,y);  
axis('equal');

3. axis('off'): This statement turns off the coordinate axis.

Example:

x = 0:pi/100:2*pi;  
y = sin(x);  
plot(x,y);  
axis('off');

4, axis('tight'): This statement sets the range of the coordinate axis to be equal to the minimum and maximum values ​​of the plotted data, but it will not automatically Adjust the proportions.

Example:

x = 0:pi/100:2*pi;  
y = sin(x);  
plot(x,y);  
axis('tight');
