loglog plots don't always use log scale

Sometimes using loglog does not change the scale to a logarithmic scale.
h=10.^-(0:5);
err=[1.4 1.04 1.004 1.0004 1.00004 1.000004];
loglog(h,err,'-o')
The y-axis is not a log-scale. Indeed, using loglog(err, err) makes both axes not use a log scale.
How does loglog choose? Or is this a bug?

The y axis is on log scale. Compare the distance between the bottom (1.0) and the tick above it (1.05) to the distance between the top two ticks (1.35 to 1.4). Obvious difference.

Aha... The range of values is so small, the scale isn't as obviously log as the x-axis. But it is!!
Thank you for your answer!

Hi, How do I equalize the log scale in the y axis as it does in the x axis? How we make the y axis also on log 10 scale (to be similar with the x axis) even though the y axis value range is much smaller than x axis?
