Issue:
In some cases scaling with logarithmic axes behaved strange. When you move in chart or scale it fixes the axes in scale of 0 to 1.
There is no way to get out of that state (only restart an app)
Reason:
In LogarithmicRenderer2D.java:worldToView operation Math.log10(val) with val=0 gives you Infinite.
This mess up computations.
Proposed solution:
Limit computation results to 0 if result is infinite.
