How to adjust plot scaling/divisions

Hi Everyone, I have the following plots:

I want to show the values between the limits 1000 and 500 on the y-axes. MATLAB automatically chooses to show only the limit values. I would appreciate any help on this.Thanks.

ylim([500 1000])

doc ylim % for details

"...the intermediate values still don't show"

Then set ticks where you want them...

set(gca,'ytick',[500:100:1000])

Hadn't actually noticed the two axes as the color on the RH one is quite light and doesn't show well...anyway, presuming that it's plotyy, there are two axes handles from a call such as

hAx=plotyy(xL,yL,xR,yR);  % where the two axes handles are in hAx

Now use those two handles in the call to ylim and to set the tick values...or, since know want each just make a single call to set

set(hAx(1),'ylim',[500 1000],'ytick',[500:100:1000]) % LH axes

Now repeat with desired values for the RH axes as

set(hAx(2), 'ytick',[0:100:500]) % RH axes

This helps to essentially zoom into the plots but the intermediate values still don't show

Works great thanks a lot. Do you know how I can do the same on the other y axis?

Perfect! Thanks a million dpb.

You're welcome...note if you have a newer release there are methods to set most all the graphics properties rather than using set directly, but I don't much see the point in writing

ax.XTick = [-3:1:3];
ax.XTickLabel = {'-3\pi','-2\pi','-\pi','0','\pi','2\pi','3\pi'};

as compared to

set(ax, 'XTick', [-3:1:3], ...
        'XTickLabel',{'-3\pi','-2\pi','-\pi','0','\pi','2\pi','3\pi'})

The methods require two separate statements whereas with the set call you can set all properties for a given axes in one call.

Or, you can use the array version and handle multiple axes and values for each in one call. It seems to me like a case of OO simply for it's own sake rather than providing anything additional in either functionality or in syntax.
