On a log scale, the powers of ten are the major ticks, and the in between ticks are
the minor ticks. Only major ticks have labels.

You could use a dummy series to add tick labels, using the following example. You
don't need to use crosses on the dummy points, use the minor ticks instead. Use the
values as labels (20, 30, etc.) and the logs of these as the coordinate along the axis.

My chart has y-axis values on a scale from 10 to 100 in increments of 10 per
each tic. When I set the scale to logarithmic, the only two tic values left
appearing on the axis are 10 and 100. How do I get the values 10, 20, 30,
...., 100 all to appear on the axis?
