Area chart Series

Question

I think my question is a little silly, but I couldn't find the answer in the examples!

I create a area chart and I need to change the name of the series, in the legend of the graph

here:

final CategoryDataset dataset = DatasetUtilities.createCategoryDataset(
    "Series ", "Type ", data
);

When a put "Series", it appears in the legend, something like this: Series 1, Series 2, Series 3.....

Is it possible to change their names, and each one has a different name?

You don't _have_ to use that utility class to create the dataset. See this [example](http://www.java2s.com/Code/Java/Chart/JFreeChartBarChartDemo.htm) which manually builds up a `DefaultCategoryDataset` — DannyMo, Aug 06 '13 at 18:22

The DatasetUtilities API is here. Looking at createCategoryDataset(),

public static CategoryDataset createCategoryDataset(
    java.lang.Comparable[] rowKeys,
    java.lang.Comparable[] columnKeys,
    double[][] data)

note in particular,

Row and column keys are taken from the supplied arrays.

It looks like you can just pass in an array of the values that you want.
