Examples of org.jfree.data.category.DefaultCategoryDataset.incrementValue()

org.jfree.data.category.DefaultCategoryDataset.incrementValue()
Adds the specified value to an existing value in the dataset (if the existing value is null, it is treated as if it were 0.0). @param value the value. @param rowKey the row key (null not permitted). @param columnKey the column key (null not permitted). @throws UnknownKeyException if either key is not defined in the dataset.

     * Some checks for the incrementValue() method.
