TAChart: Minor axis tics

What is the best way to create minor tics at the axes? With that I
mean intermediate axis markers between the labelled ones. Delphi's
TeeChart does this automatically. I know there is a demo how to do
this with TAChart, but this is quite complicated. Isn't there an
easier way?

At the moment, the only method is shown in axisdemo/Submarks.
Do you have any suggestions for a simpler interface?

I think easier creation of minor ticks requires a second built-in set
of marks ("MinorMarks"). The Distance parameter should be calculated
from that of the major marks: e.g. if major tick distance 0.05, then
minor tick distance 0.01, etc. The minor marks should be drawn a few
pixels smaller than the major marks, and labelling should be off by
default.
