Anyone know is there log and/or ln chart?

[RC]

Most of Java charts I have found are
XY, bar(high-low vertical or long-short horizontal),
pie, etc. So far I haven't found a Java chart
can do log (common logarithm) and ln (natural logarithm).

Does anyone out there know where I can find a Java chart
that can draws log and ln?

Fanx (Thanks)!

See http://mindprod.com/jgloss/graph.html for candidates.

In a pinch you can just plot ln( y ).
