how to plot Double y axis?

This value how plot in matlab R2015 version?

Distance (X axis) TIFF (y1) Percentage (y2)

Fixed Float

1 2 99 1

6 6 97 3

10 8 94 6

15 10 92 8

22 15 89 11

x = linspace(0,10);

y = sin(x);

yyaxis left

plot(x,y)

z = (8*x);

yyaxis right

plot(x,z)

ylim([-150 150])

I put an example above. The x axis is singular. And we have two Y axis. The limit of Y axis is [-150,150]. I hope it helps!

Thank you for your responce. But i have three axis, how i plot it in y double axis?

x = [1 6 10 15 22]; (Distance)

y1 = [2 6 8 10 15]; (TIFF)

y2 = [99 97 94 92 89]; (Percentage)

y3= [1 3 6 8 11]; (Percentage)

[Yusuf Suer Erdem]

Just try the way below and it will work for you:

x = [1 6 10 15 22];

y1 = [2 6 8 10 15];

y2 = [99 97 94 92 89];

y3= [1 3 6 8 11];

plot(x,y1,x,y2,x,y3)

For version 2016a aor later, use yyaxis instead

x = [1 6 10 15 22];
y1 = [2 6 8 10 15];
y2 = [99 97 94 92 89];

[hAx,hLine1,hLine2] = plotyy(x,y1,x,y2);
ylabel(hAx(1),'TIFF') % left y-axis 
ylabel(hAx(2),'Percentage') % right y-axis

[SOMNATH MAHATO]

Thank you for your answer. But Y axis have 3 line.

x = [1 6 10 15 22]; (Distance)

y1 = [2 6 8 10 15]; (TIFF)

y2 = [99 97 94 92 89]; (Percentage)

y3= [1 3 6 8 11]; (Percentage)

Kindly provide the code of this. Thank you in advance.

You might need a function from file exchange. Have a look at this.

I have tried many times but shows errors. can you try it for me, if possible?

I can't change right y axis color. How i can change it?

yyaxis right
ax = gca(); 
ax.YAxis(2).Color = 'r';

[SOMNATH MAHATO]

Below this this code y axis right side color not change. Have a look with this code.

x = [1 6 10 15 ];

y1 = [1 2 2 2 ];

y2 = [100 99.99 89.73 78.22];

figure('Color','w')

[hAx,hLine1,hLine2] = plotyy(x,y1,x,y2);

xlabel ('Distance (km)')

ylabel(hAx(1),'TFFS (s)') % left y-axis

ylabel(hAx(2),'Fix solution Percentage (%)') % right y-axis

grid on

yyaxis right

ax = gca();

ax.YAxis(2).Color = 'r';
