how to specify y axis?

how to spesify left y axis as follow:

(0 500 1000)

[Ibrahim AlZoubi]

I use ylim([1 1000])

Try this:

clear 
clc
clf
x=1:1:24
yyaxis right
y =[0,0,0,0,0,2.879097736,22.91004173,45.42868867,58.31916249,64,65,66,65,64,60,53.00046608,32.17312477,9.879732541,0,0,0,0,0,0];
plot(x,y,'k','LineWidth',2.5)


yyaxis left

z=[242.5325006,242.5325006,242.5325006,242.5325006,0,13.29108368,66.80670854,139.455836,196.175253,215.5559079,218.7020474,220.3220205,218.7020474,215.5559079,196.175253,139.455836,66.80670854,13.29108368,0,242.5325006,242.5325006,242.5325006,242.5325006,242.5325006];

n=[0,0,0,0,0,76,344,607,748,816,840,850,841,835,773,661,435,169,0,0,0,0,0,0]

plot(x,n,'b',x,z,'b','LineWidth',2.5)

set(gca,'YLim',[0 1000],'YTick',[0 500 1000],'YTickLabel',[0 500 1000])

I forced the limit of the left-hand y-axis to be [0 1000], so that the ticks show up.

you're amazing thank you so much!

set(gca,'YTick',[0 500 1000],'YTickLabel',[0 500 1000])

Not working

[the cyclist]

Here is a simple example that shows that this syntax works:

figure
plot(1000*rand(7))
set(gca,'YTick',[0 500 1000],'YTickLabel',[0 500 1000])

Perhaps you are doing something afterward that changes it? Maybe you could post the code that creates your figure.

Here is a link to the documentation that explains what I did.

what is rand 7

[Ibrahim AlZoubi]

clear 
clc
clf
x=1:1:24
yyaxis right
y =[0,0,0,0,0,2.879097736,22.91004173,45.42868867,58.31916249,64,65,66,65,64,60,53.00046608,32.17312477,9.879732541,0,0,0,0,0,0];
plot(x,y,'k','LineWidth',2.5)


yyaxis left

z=[242.5325006,242.5325006,242.5325006,242.5325006,0,13.29108368,66.80670854,139.455836,196.175253,215.5559079,218.7020474,220.3220205,218.7020474,215.5559079,196.175253,139.455836,66.80670854,13.29108368,0,242.5325006,242.5325006,242.5325006,242.5325006,242.5325006];

n=[0,0,0,0,0,76,344,607,748,816,840,850,841,835,773,661,435,169,0,0,0,0,0,0]

plot(x,n,'b',x,z,'b','LineWidth',2.5)

this's my code

[the cyclist]

rand(7)

was just me generating some random numbers to plot, to illustrate that my code suggestion worked in that case.
