Hi all
thank you for helping
i want to draw figure in matlab that has two main effect (temprature and effiency ) in Y axis in sides when X axis is same range
for example
x=[11 22 33 44 55];
y1E=[0.5506 0.5925 0.6212 0.6419 0.6573]; %Effeiceny 1
y1T=[43.7529 45.0284 45.9019 46.5297 46.9987]; %Temprature 1
when i use this
Ax=plotyy(x,y1E,x,y1T);
hy1=get(Ax(1),'ylabel');
hy2=get(Ax(2),'ylabel');
set(hy1,'string',' efficiency 1');
set(hy2,'string','Temperature1');
xlabel('Number ');
it gives me figure with 1x axis and 2 Y axis in both side
i want to add another Effeiceny and Temprature with same X and in same figure
y2E=[0.3 0.4 0.6 0.8 0.3]; %Effeiceny 2
y2T=[50 45 43 47 55]; %Temprature 2
how can i do that
thank you for this helping

thank you very much for your comment , I found the best one untill now is using plot4y https://www.mathworks.com/matlabcentral/fileexchange/4425-ploty4-m

You can use this function from the file exchange.
clc
clear
t=linspace(0,pi,100);
sinplot=sin(t);
cosplot=cos(t);
tanplot=tan(t);
linecolors={'r' [0 .5 0] 'b'};
h3i=plotNy(t,sinplot,1,t,cosplot,2,t,tanplot,3,...
'Linewidth',1,'YAxisLabels',{'' '' ''},'XAxisLabel','Deg',...
'LineColor',linecolors,...
'FontSize',12,...
'Fontname','TimesNewRoman',...
'Grid','on',...
'LegendString',{'Sin' 'Cos' 'Tan'});
for i=1:length(h3i.ax)
set(h3i.ax(i),'ycolor',linecolors{i});
