@Repeatable(Charts.class)

@Target({FIELD,METHOD})
public @interface Chart
```
To display a chart using the values from a collection.
Applies to collections.
Example:
```
  @Chart
  Collection employees;  
 
```
It could display a chart with several bars, one for each employee, for example.
In this case OpenXava tries to determine automatically whose properties identifies each entity, to use them as labels, and also try to choose numeric values from entities susceptible to be shown in the chart.
However, you can determine explicitly what properties use, like in this example:
```
  @Chart(labelProperties = "firstName, lastName", dataProperties = "salary, bonus")
  Collection employees;  
 
```
In this case the concatenation of firstName and lastName is used as label, and the salary and bonus properties as data.
Since v7.5 you can also specify the type of chart to use:
```
  @Chart(type = ChartType.LINE, labelProperties = "month", dataProperties = "sales")
  Collection sales;  
 
```
Available chart types are BAR (default), LINE and PIE.
