java.lang.Object | +--com.jrefinery.data.AbstractDataset | +--com.jrefinery.data.AbstractSeriesDataset | +--com.jrefinery.data.DefaultIntervalCategoryDataset
A convenience class that provides a default implementation of the IntervalCategoryDataset interface.
The standard constructor accepts data in a two dimensional array where the first dimension is the series, and the second dimension is the category.
Constructor Summary | |
DefaultIntervalCategoryDataset(double[][] starts,
double[][] ends)
Creates a new dataset. |
|
DefaultIntervalCategoryDataset(java.lang.Number[][] starts,
java.lang.Number[][] ends)
Constructs a dataset and populates it with data from the array. |
|
DefaultIntervalCategoryDataset(java.lang.String[] seriesNames,
java.lang.Number[][] starts,
java.lang.Number[][] ends)
Constructs a DefaultIntervalCategoryDataset, populates it with data from the arrays, and uses the supplied names for the series. |
|
DefaultIntervalCategoryDataset(java.lang.String[] seriesNames,
java.lang.Object[] categories,
java.lang.Number[][] starts,
java.lang.Number[][] ends)
Constructs a DefaultIntervalCategoryDataset, populates it with data from the arrays, and uses the supplied names for the series and the supplied objects for the categories. |

public DefaultIntervalCategoryDataset(double[][] starts, double[][] ends)
starts
- the starting values for the intervals.ends
- the ending values for the intervals.public DefaultIntervalCategoryDataset(java.lang.Number[][] starts, java.lang.Number[][] ends)
The arrays are indexed as data[series][category]. Series and category names are automatically generated - you can change them using the setSeriesName(...) and setCategory(...) methods.
starts
- the start values data.ends
- the end values data.public DefaultIntervalCategoryDataset(java.lang.String[] seriesNames, java.lang.Number[][] starts, java.lang.Number[][] ends)
Category names are generated automatically ("Category 1", "Category 2", etc).
seriesNames
- the series names.starts
- the start values data, indexed as data[series][category].ends
- the end values data, indexed as data[series][category].public DefaultIntervalCategoryDataset(java.lang.String[] seriesNames, java.lang.Object[] categories, java.lang.Number[][] starts, java.lang.Number[][] ends)
seriesNames
- the series names.categories
- the categories.starts
- the start values data, indexed as data[series][category].ends
- the end values data, indexed as data[series][category].Method Detail |
