Clear selection Functionality in Listbox

[#1]

Hi All,

I have a line chart displaying the company values based on selection made in List box.If no selections has been made it displays all by default.

Can we implement the same functionality in list box and specified 'ALL' as an option.??How can we do that??

I mean,i want the "ALL " option in List box.

Functionality: When user selected Company1 the values of Company1 has to be displayed in line chart.When user click "ALL" it get back to default screen !
