Want to change the range of a single axis of a plotyy figure

Hi

I want my x-axis to be tight to the data on a plotyy graph. I can't seem to do it without messing up the axes.

My data ranges from 1e-5 to 1e3 and it's a semilogx plotting function. Is there a way I can use axis([...]) to specify all three ranges (x, y1, y2) at once?

Thanks for any help Mike

There is no way to specify the limits all at once.

[ax h1 h2] = plotyy(x,y1,x,y2);
xlim(ax(1), ...);
xlim(ax(2), ...);
ylim(ax(1), ...);
ylim(ax(2), ...);

but using this command disrupts the alignment of two plots in vertical axis (on ranges from -10 to 50 other 0 to 0.003). If I want the same alignment as it done automatically by plotyy, it would be great. So how to do that??

figure;
ylim([1e-5 1e3]);

or

goto Edit -> Axes Properties -> then select X axis and change range as your need

I think there are two axes and both of these solutions only change one of the two, resulting in an overlapping set of axes. My x data is the same for both plots, so I'd like the x axis to be unique.

[Muruganandham Subramanian]

If you need to change x axis range is b/w 1e-5 to 1e3, you can use

xlim([1e-5 1e3])

or if it's not, can you explain precisely?

[Michael]

That is exactly what I want to do, but it's not working because it seems to generate a second axis. The original axis (not tight) is still there. I think the fact that it's a plotyy figure has an influence on the answer.
