Matlab | drawing of three ordinate diagram based on block diagram layout

About the code

This picture is on the official account 「 Marine and Atmospheric Sciences 」 What you see , Brother official account has given the drawing method of this kind of diagram , But it is found in the relatively new version (R2021a And after ), have access to tiledlayout The block diagram layout is more natural , So I got this push . For the old version, you can click the following jump link ： Jump

Complete code and effect

%  Generate a random set of data 
x=0:.05:3*pi;
noise=(rand([1,length(x)])-0.5);
y1=sin(x-2)-5+noise.*.1;
y2=6.*cos(0.5*x)+noise.*.1;
y3=1.5.*sin(x)+0.5.*cos(x)+noise.*.3;

%  Create a layout 
tdl=tiledlayout(1,10);
%  Reduce the blank area , Delete 
tdl.TileSpacing='tight';
tdl.Padding='compact';

%  The coordinate region of the first curve  ==============================
ax1=axes(tdl);hold on
ax1.LineWidth=1.5;        %  Shaft thickness 
ax1.YColor='k';           %  Axis color (k: black )
ax1.XLabel.String='x';    % x Axis labels :'x'
ax1.YLabel.String='var1'; % y Axis labels :'var1'
ax1.Layout.TileSpan=[1 9];%  The coordinate area accounts for 9/10 Width , Third y Axle occupation 1/10 Width 
%  Here is the first  1  Group data plot - - - - - - - - - - - - -  
plot(ax1,x,y1,'k','LineWidth',2)

%  The second curve coordinate area  ==============================
%  Other properties are similar to the previous coordinate region 
%  Set up Color by 'none'
%  The coordinate area background can be set to transparent 
%  Let the previous drawing not be blocked 
ax2=axes(tdl);hold on
ax2.LineWidth=1.5;
ax2.YAxisLocation='right';

ax2.Layout.TileSpan=[1 9];
%  Here is the first  2  Group data plot - - - - - - - - - - - - -

%  The coordinate area of the third curve  ==============================
ax3=axes(tdl);hold on
ax3.Color='none';
ax3.YColor='none';
ax3.Layout.TileSpan=[1 9];
%  Here is the first  3  Group data plot - - - - - - - - - - - - - 
plot(ax3,x,y3,'b','LineWidth',2)

%  Let the coordinate region x Axis Association 
linkaxes(tdl.Children,'x')
%  Draw the third y Axis , Occupy 1/10 Width , The color is b: Blue 
ax4=axes(tdl,'LineWidth',1.5,'YAxisLocation','right',...
