Parameters:
space - the space along the entire axis (in Java2D units).
Parameters:
axis - the category axis.
Parameters:
categories - the number of categories.
Parameters:
series - the number of series. The width of one series. |

Parameters:
plot - the plot.
Parameters:
domainAxis - the domain axis.
Parameters:
rangeAxis - the range axis.
Parameters:
dataset - the dataset.
Parameters:
row - the row index (zero-based).
Parameters:
column - the column index (zero-based).
Parameters:
pass - the pass index. |
| equals | | public boolean equals(Object obj)(Code) | | Tests an object for equality with this instance.
Parameters:

| getItemMargin | | public double getItemMargin()(Code) | | Returns the item margin.
The margin. |
| getMaximumItemWidth | | public double getMaximumItemWidth()(Code) | | Returns the maximum width, as a percentage of the available drawing
space.
The maximum width. |
