# GroupRenderer
|
|
`GroupRenderer` is a special implementation of `XYSeriesRenderer` that combines multiple instances
|
|
of `XYSeries` into a single virtual series of s higher dimension. Examples of `GroupRenderer` are:
|
|
|
|
* BarRenderer
|
|
* CandlestickRenderer
|
|
|
|
Let's take a quick look at `CandlestickRenderer`. A candlestick chart is basically a two two dimensional
|
|
representation of a complex value; for every value of x a single candlestick is drawn, but there are
|
|
four values (dimensions) that make up each candlestick:
|
|
|
|
* open
|
|
* close
|
|
* high
|
|
* low
|
|
|
|
When a series is added to the plot with a formatter associated with a renderer that extends `GroupRenderer`,
|
|
all series added with formatters of the same type are automatically "grouped" together during rendering. |
