Hi,

A newbie to the group and in no way an excel guru.

I need some help. I want to display a bar chart only for that data
that I already have. For example, the data I currently have is only
till end of January. When I do have data for February, I will fill
that in, and only then do I want the chart to show February data. At
present, for the range I have selected, I am getting all the data
feilds on the x-axis till December but with no values. What I would
like to see is that my chart should show only the data for January,
and after I fill in data for February, then it should come in the
chart.

I hope I have explained my question clearly.

Thanks.
