Since you are able to generate the plot, the only thing is to have it scaled to same values on both sides of y-axis. You can use the 'ylim' command after the 'plot' command in your code. Below is a sample code where you can see the y-axis being scaled to same values on both the vertical axes.

x = linspace(0,10,50);
y1 = sin(x);
figure
yyaxis left
plot(x,y1)
ylim([0 1]);
%title('Combine Plots')

hold on
y2 = sin(x/2).^x;
plot(x,y2)
hold off

You can see the difference in the figure once you comment the 'ylim([0 1])' command in the above sample code. Read more on ylim command using below link:
