Excel 2007 Query

[anuran]

Arrgh. I have a line chart where the Y-axis has minimum value -0.2, maximum 10.0, major unit 2.0 a nd minor unit automatically 0.4. The bastard thing is showing a major gridline at 9.8, and although there is a gridline at 0 there is no number "0" there, so it's not clear where zero is to the thickos at [government agency] who have to read my report. I'd quite like the maximum to be TEN, or/and, at the very least, to have the number "0" NEXT TO THE ZERO GRIDLINE. I didn't mean for that last bit to be in caps locks, but actuall it expresses today's Excel Rage nicely. Anyone?
