I am using Excel 2007.

I want to draw chart of data that is in dd:hh:mm:ss format. But when I add those cells to chart not is shown on it. I am using scatter/x,y chart.

I wonder if Excel isn't recognising the dd:hh:mm:ss format. I didn't find it in standard time-formats so I made custom format for it. Or maybe Excel anyway thinks that those cells are text, not time?

How could I make Excel to understand this data? Or how could I convert it to some other form that Excel could use?
