Try extending XYLineAndShapeRenderer -- maybe start by looking at the code around drawPrimaryLine() and drawItem()?

This logarithmic axis provided by mhilpert is fantastic. One thing that I noticed with both JFreeChart is that it works well to chart any numbers below 1 as well, thanks to what is happening in adjustedLog10() method... or in mhilpert's fix, adjustedLog() which properly handles different bases. But ...

This is happening because PeriodAxis uses its own PeriodAxisLabelInfo array. You can work around this by doing creating your own PeriodAxisLabelInfo array and specify the desired stroke / paint etc. using the FULL constructor for PeriodAxisLabelInfo. The constructor of HPeriodAxis uses the short for...

I added this to a subclass of XYPlot... This certainly solved my problem of knowing where the user clicked. -g /** * These a...
