My guess is that your spike is dwarfing all of your legitimate usage to the point that can't see it on the graph. The data's probably there, but because of the scale of your graph, it isn't visible.
Do an rrd fetch from the command line to see if your data is in the RRD. If it's there (I suspect that it is), then you've found the problem. Replace that spike with NaN (RRDTool assumed that your counter rolled over instead of resetting) and your graphs will go back to normal.

Now I have no graphs, just flat lines, with a single spike when the counter was reset. So the resetting of the counter appears to have 'wiped out' 6 weeks of history. using rrdtool info on the rrd and looking at the time the counter was reset I can't see a spike in the data, the value is 50(ish) on each increment. I must be missing something but I can't see what it is!!!!
