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

For cases like this, I doubt plotyy() is the best thing to be using. If you're running R2016a or newer, you can probably try building the plot using yyaxis() instead; I'm not, so this is something I can't test for you.

Generally, in the case when one needs to do complicated plots with multiple coincident axes (e.g. axes in both metric and US customary units), it's best to build the figure by manually overlaying axes objects and working from there. For instance:

https://stackoverflow.com/questions/28634426/create-an-xy-plot-with-two-y-axis/28634655#28634655

Unsurprisingly, there are at least a few tools on the File Exchange which appear to address this inconvenience.

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});	
end

You can use addaxis function to plot from the file exchange.

clc
clear
x = 0:.1:4*pi;
plot(x,sin(x));
addaxis(x,sin(x-pi/3));
addaxis(x,sin(x-pi/2),[-2 5],'linewidth',2);
addaxis(x,sin(x-pi/1.5),[-2 2],'v-','linewidth',2);
addaxis(x,5.3*sin(x-pi/1.3),':','linewidth',2);
addaxislabel(1,'one');
addaxislabel(2,'two');
addaxislabel(3,'three');
addaxislabel(4,'four');
addaxislabel(5,'five');
addaxisplot(x,sin(x-pi/2.3)+2,3,'--','linewidth',2);
addaxisplot(x,sin(x-pi/1),5,'--','linewidth',2);
legend('one','two','three','four','five','three-2','five-2');
