Hello, i want to add a “DataSet” parameter inside my component. I didn’t know wich type of variable I need to declare for the “DataSet” in my java class. By exemple, their is a DataSet parameter in the Pie Chart object of Ignition Designer.

I’m adding the parameter with :

[code]public [Type of Variable] Data;  
getData()  
setData(…)

…  
addProp(“data”, “Data”, “”, CAT\_DATA); //into CommonBeanInfo[/code]  
Thanks !

The datatype is just called Dataset. Just use:

```auto
import com.inductiveautomation.ignition.common.Dataset;
```
