-The default choice for tick \emph{positions} in normal plots is to place a tick at each coordinate~$i\cdot h$. The step size~$h$ depends on the axis scaling and the axis limits. It is chosen from a list a ``feasable'' step sizes such that neither too much nor too few ticks will be generated. The default for logplots is to place ticks at positions $10^i$ in the axis' range. The positions depend on the axis scaling and the dimensions of the picture. If log plots contain just one (or two) positions $10^i$ in their limits, ticks will be placed at positions $10^{i\cdot h}$ with ``feasable'' step sizes $h$ as in the case of linear axis.

+\noindent The \TeX\ script takes the |\tick| macro as input and applies some logic. The |\ifdim\tick pt<0pt| means ``if dimension |\tick pt| $ < $ |0pt|''. The |\ifdim| is \TeX's only way to compare real fixed point numbers and the author did not want to invoke |\pgfmath| for this simple task. Since |\ifdim| expects a dimension, we have to use the |pt| suffix which is compatible with |\pgfmath|. The result is that negative numbers, zero and positive numbers are typeset differently.
