BTW, Brad ..... the problem with graphs is the 'selectivity' of the x/y ratio and their chosen start and end points...eg...
That graph 'could' demonstrate a doubling of sales.... as point 1 is half the 'height' up the scale as the third...
or...
if the bottom coord was 2,000,000 the 'high' point could easily be '2,000,010' ....still an increase...but hardly noteworthy....
