#384 Number of major ticks of log axes not preserved on re-scale

[Fellype]

To re-scale or to change curve axis reduces the number of major ticks to 1 (or sometimes 2) of axes in logarithmic scale in a graph.

The attached project has a python script to reproduce the issue in the case when the axis of a curve is changed. To test the case when a re-scale is applied, just click on the "Best fit" button after run the script.

Tested with SciDAVis 1.25, built from source (Slackware + Qt4 + python2)
