howdy

ive got a chart which gives production values by year for different
countries. the problem is one country starts production in the middle
of the data range and so excel draws the line from zero at the year
before, so it rises slowly.
i want the graph to jump straight to its value at the year production
commences; how can i do this?

(sorry if this is unclear, i would add a picture but i dont have
hosting or anything!)

thanks!
