Draw a two coordinate diagram with MATLAB (the simplest in the whole network)

Just control the left and right coordinates respectively , Don't be too simple . And it can match many kinds of graphics at will . 

 x= 1:3;
 y= [9.0725,9.075,9.5175];
 w= [229,230,207];
 yyaxis left% Control left vertical axis 
 bar(x,y);
 yyaxis right% Control the right vertical axis 
 plot(x,w);
