Set Start and End Date Easy Chart from Dropdown List dataset

I have a Dropdown List in which I have dates in two columns, how can I make an Easy Chart take the start and end date from the Dropdown List dataset when a value is selected?
This is the Dataset of the Dropdown List:

Hi rroca,
I was able to find a way to grab the date from a drop down dataset, you will have to use an expression that reads the start or end date and bind those to the easy chart’s Start Date and End Date.

Here’s an example of the expression binding:
{Root}[{Root Container.Dropdown.selectedIndex}, “inicio”]
