Hi

I using the Diagramm line to show depencies between, dates and percentage.
0% - jan
0% - feb
10% - mar
20% - apr
30 % - may
....
100% -aug

I have a expected start date at FEB and expected Enddate at SEPT.
So my idea is, that two vertical linies oder a rectangle with transparancy
color will show the start date and the end date.

Is that posible and how i could do that?

Thank you

Matthias
