I have a quick question about zooming log plots. When I implement ChartZoom on a graph containing a log axis it will throw an exception if I have zoomObj.setZoomStackEnable(true);.

The exception thrown is:
java.lang.StackOverflowError at com.quinncurtis.chart2djava.LogScale.copy(LogScale.java:73)com.quinncurtis.chart2djava.LogScale.copy(LogScale.java:73)com.quinncurtis.chart2djava.LogScale.copy(LogScale.java:73)
.
.
.

Is there a work around so I can have a zoom stack with log graphs?

Some variables I am setting are:

zoomObj.setZoomYEnable(true);
zoomObj.setZoomXEnable(true);
zoomObj.setZoomXRoundMode(ChartConstants.AUTOAXES_FAR);
zoomObj.setZoomYRoundMode(ChartConstants.AUTOAXES_FAR);
zoomObj.setZoomRangeLimitsRatio(new ChartDimension(0.01, 0.01));

The libraries were updated on Aug. 24, 2007 to reflect the fix to this zooming log axis bug.
