#139 Enhanced LogarithmicAxis

[m.hilpert]

I adjusted my LogarithmicAxis and PercentageAxis to the
changed API of JFreeChart 0.9.9. Attached are
screenshots and code.

After migrated to 1.0.0-pre2 I now have a current version of
my improved LogarithmicAxis. It is compatible to the
JFreeChart LogarithmicAxis, so best would be to replace its
code with this one ;-)

It supports custom logarithm bases and tick label factors.
With this enhanced LogarithmicAxis, even more
sophisticated mathematical/financial axis can be realised
(e.g. PercentageAxis).

1.0.0-pre-2 compliant Version of enhanced LogarithmicAxis

The attached file has a wrong package declaration:
package chart;

The correct one should be
package org.jfree.chart.axis;

This is not a wrong package declaration, it is _my_ package declaration (just
an example). Of course, I can't use org.jfree.chart.axis as it doesn't belong to
the JFreeChart API. The author of JFreeChart has to decide if he wants to
include this class into the JFreeChart API. Then it would be renamed to its
package name. So, nothing "wrong" here ... (you should read the Java
Tutorial about package names!).

Updated to JFreeChart 1.0.0-rc1

I found out that this class will distort my graphs if the data values are
between 0 and 1. If I shift (multiply) my data to values above 1,
MyLogarithmicAxis behaves as expected (i.e. behaves like the original
LogarithmicAxis).

The current version just implements a vertical improvement. If you hase it as a horizontal axis, it behaves like the original JFreeChart LogarithmicAxis ... including the problems for values < 1. The next version will also support horizontal axis.

New: refreshTicksHorizontal()

New version of MyLogarithmicAxis with that now supports horizontal axis.
