Dynamic origin of the graph data

I have a table in Excel, 'Tab_Visitas' which has the hits for the month.

What I wanted to do was make a line chart, but only with the selected date and prior to the selected date, type this:

Obtaining dates already have:

DataSelecionada:= DATE($Q$2;MATCH($P$2;Tab_Meses;0);1)
DataAnterior:= EDATE(DataSelecionada;-1)

How do I put the chart only display the data of that month and the previous one?
