My values are:-

x-axis(time): 0, 1, 3, 7
y-axis(colonies): 2890000, 8910000, 13000, 450, 50, 1700
(there are more of these but this includes the highest and lowest values!)

(I can't do any log graphs for this. So, I'm currently doing this in Microsoft Excel and its producing a useless huge graph where i can't see the values! The numbers are spread so hugely that the graph ignores small values. But I'm sure there's a way to construct it nicely. Hence, require your help please.)

Is this a graph of bacterial death? Can you plot them as percent remaining, using 2890000 as 100%?

I see two solutions - logarithmic scale or 2~3 segment Y-axis (eg. 0-2000, 10000-20000, 1000000-10000000).

Not an answer, but a question:

are those numbers from the same dilution? Or from different ones?

If its option 2: put each dilution on its own graph.

If you don't know it, then ask it! Better to ask and look foolish to some than not ask and stay stupid.
