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

Accepted answer

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), ...);

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.

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?
