Hi Here's how I solved this problem: I taylored the number of bins to the data. protected void addSeriesToDataSet(HistogramGenerator.HistogramSeries series) { double[] values = series.getValues(); if(values.length==0) { //no data? I'll let HistogramGenerator handle it ;) super.addSeriesToDataSet(series); return; } double v = values[0]; double min = v; double max = v; for(int i=1;i<values.length;i++) { v = values[i]; if(v<min) min = v; if(v>max) max = v; } int bins = (int)(max - min +1); dataset.addSeries(series.getName(), values, bins); } This is part of a HistogramGenerator class extension with "UnitWideBin" in the name :) hope this helps, Gabriel On Tue, 7 Jul 2009, MASON-INTEREST-L automatic digest system wrote: > There is 1 message totalling 22 lines in this issue. > > Topics of the day: > > 1.
