public void drawItem (Graphics2D g2, CategoryItemRendererState state, Rectangle2D dataArea, CategoryPlot plot, CategoryAxis domainAxis, ValueAxis rangeAxis, CategoryDataset dataset, int row, int column, int pass)

Draw a single data item.

Parameters
g2 the graphics device.
state the renderer state.
dataArea the data plot area.
plot the plot.
domainAxis the domain axis.
rangeAxis the range axis.
dataset the dataset.
row the row index (zero-based).
