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 Container.Dropdown.data}[{Root Container.Dropdown.selectedIndex}, "inicio"]

For references:

> Very simple question. I’m sure the answer is simple too. Is there an expression function to read a value from a dataset? Something like getValueAt in Python. Thanks.
