Matlab drawing | some common settings of axis

There are many uses for graphics , We are reading some papers , I often see some very beautiful pictures , This will make our understanding of the content more profound . Commonly used drawings have been written before , Write here after drawing , how Set the coordinate axis , Make the picture more in line with actual needs ！

Basic graphics ：

 Code ：x=0:pi/4:2*pi;y=sin(x);plot(x,y,'-co');

This picture is drawn directly , Next, set the coordinate axis ！

01

axis off: Close all axis labels 、 scale 、 background ​​​​​​​

x=0:pi/4:2*pi;y=sin(x);plot(x,y,'-co');axis off;

02

axis([xmin xmax ymin ymax]): Set the coordinate range of the drawing , Respectively x The minimum of the axis 、 Maximum ,y The minimum and maximum value of the shaft .

​​​​​​​

x=0:pi/4:2*pi;y=sin(x);plot(x,y,'-co');axis([0,2*pi,-1,1]);

03

axis ij: Set the axis to matrix mode . At this time, the horizontal coordinate axis has a value from left to , Vertical coordinates from top to bottom

​​​​​​​

x=0:pi/4:2*pi;y=sin(x);plot(x,y,'-co');axis ij;

04

axis square: Set the axis to square

​​​​​​​

x=0:pi/4:2*pi;y=sin(x);plot(x,y,'-co');axis square;

05

axis equal : Set screen aspect ratio , Make everyone sit The scale axis has uniform scale interval

x=0:pi/4:2*pi;y=sin(x);plot(x,y,'-co');axis equal;
