2. DateTickUnit: showing dates at 00:00 otherwise time only jfree.orgI don't believe that DateAxis supports multiple concurrent formats. In my code I have the following hack to achieve this: I subclassed DateAxis, and added the following override of refreshTicksHorizontal Code: Select all public java.util.List refreshTicksHorizontal(Graphics2D g2, double cursor, Rectangle2D plotArea, Rectangle2D dataArea, RectangleEdge edge) { java.util.List |
3. Why not show first date jfree.orgYour setTickUnit() call specifies that ticks should be placed along the axis at 6 month intervals. The first tick label displayed is determined by looking at the lower bound of the axis, calling previousStandardDate() for the lower bound, then stepping forward from there in 6 month intervals. In your case, this will select Jan-2003 for the first tick label, then Jul-2003, ... |

8. sorting by date jfree.orgI presume you are using a CategoryAxis (and CategoryPlot). The CategoryAxis displays categories in the order that you add them to the dataset. You *can* use dates for the categories, but JFreeChart won't treat them in a special way, it looks at them as simple category labels. For date-based data, you should use a DateAxis, which works with the XYPlot class. ... |

35. How to get java.util.date from TimeSeriesDataItem? jfree.orgIt depends on your dataset. At the very least, you can rely on the methods in the XYDataset interface (e.g. getXValue() will return the number of milliseconds since 1-Jan-1970).
