how to draw two y axis?

I've two lines:

x=[0,0,0,0,0,76,344,607,748,816,840,850,841,835,773,661,435,169,0,0,0,0,0,0];
z=[4.8,4.4,4.1,4.4,4.8,5.1,7.2,7.2,7.2,7.2,7.2,6.2,5.1,6.2,6.2,8.2,8.2,7.2,7.2,5.1,4.1,5.1,9.3,8.2];
months_of_the_year=0:1:23;  
plot(months_of_the_year,x,'-',months_of_the_year,z,'--','LineWidth',2.5)

when I plot them the porblem is one of these lines is not visable, how can i draw two y axis which makes me see the second line?

how to make each of these two y axis for each line?

Can you clarify, what do you mean by two Y axis? Are you referring variable z as second Y axis?

As suggested by Madhan, you can use yyaxis function to show 2 different scales on yaxis.

In your case,

x=[0,0,0,0,0,76,344,607,748,816,840,850,841,835,773,661,435,169,0,0,0,0,0,0];
z=[4.8,4.4,4.1,4.4,4.8,5.1,7.2,7.2,7.2,7.2,7.2,6.2,5.1,6.2,6.2,8.2,8.2,7.2,7.2,5.1,4.1,5.1,9.3,8.2];
months_of_the_year=0:1:23;

yyaxis left
plot(months_of_the_year,x,'-')
yyaxis right
plot(months_of_the_year,z,'--','LineWidth',2.5)
