Vertical or background info in a chart

Hello all,

I have a line chart. The X axis is the time. The Y axis contains the value
I want to display.

I would like so show that during the period a given event happened, and
then disappeared
later.

This could be done two ways:
    1) One vertical line with a given legend at the date it happened and
one vertical line with another
legend when the event finished
    2) During the period the event happened we could have a special
background color for the chart.

Is it possible to implement one or both of these solutions?

Many thanks

Gilles
