I was trying to make a simple line chart (Excel 2000). I had the following
columns: Date, Heat 05, Air Cond 05, Heat 06, Air Cond 06 all populated with
the running time of the furnace or air conditioner up to today's date.

The chart would omit the first column of data to the right of the Date
column until I deleted the heading "Date" from the Date column.

Everything else in the chart appeared normal.

Is this normal behaviour or have I stumbled upon a bug of some kind?
