| 5 * src/main/java/de/intevation/gnv/chart/DefaultHistogram.java: Use | |
| 6 AdvancedHistogramDataset as dataset for histograms instead of JFreeChart's | |
| 7 HistogramDataset. Adjusted the calculation of bin width and number of bins | |
| 8 for this. | |

| 10 * src/main/java/de/intevation/gnv/chart/AdvancedHistogramDataset.java: This | |
| 11 class is mainly a copy of JFreeChart's class HistogramDataset. The | |
| 12 difference between these two classes is, that AdvancedHistogramDataset | |
| 13 takes an argument for setting the bin width as well as an argument to | |
| 14 adjust the number of bins - HistogramDataset just takes the number of | |
| 15 bins. The reason why AdvancedHistogramDataset doesn't inherit from | |
| 16 HistogramDataset is, that basic attributes of that class have private | |
| 17 access. | |
