1. XYDataset problem with null items in a serie (1.0.0-rc1) jfree.orgI wanted to draw a ScatterPlot from an XYDataset where some series have "holes" in some items. With version 1.0.0-rc1, default getXValue/getYValue is to return Double.NaN if the Number from getX/getY is null. I found this brings a problem in data.general.DataSetUtilities.iterateDomainBounds(), giving minimum/maximum values == Double.NaN. I've changed lines 699, 700 for: if (!Double.isNaN(lvalue)) minimum = Math.min(minimum, lvalue); if (!Double.isNaN(uvalue)) maximum ... |
2. Converting an XYDataset into IntervalXYDataset jfree.orgHi, I have an XYDataset which reads data from a JDBC (a date and a single series of numbers). I can call ChartFactory.createTimeSeriesChart without any problems. However, I need to also be able to call ChartFactory.createXYBarChart, which accepts an IntervalXYDataset, not XYDataset. Can anyone assist me with this conversion? Thanks in advance. |

8. LevelRenderer with XYDataset jfree.orgI am trying to use the feature of the LevelRenderer with an existing XYDataset. I have two different XYdatasets being plotted on the same XYPlot. I wish to have one of those datasets show up on the plot as a line (or a level). This would look similar to how the LevelRenderer class is used in the OverlaidBarChartDemo2 without the other ... |

12. XYDataSet jfree.orgHi, could you please specify which classes your are talking about? The XYDataset-Interface only declares methods for getting data out (since this is what is needed during generation of the chart) but it does not declare any methods for getting data in. The methods to put data in an XYDataset-instance are dependent on the implementation at hand. If you want to ... |
