Adjusting the width of the chart only widens the distance between 
each value as the highest value (less than 100) is just further from 
0 than before the widening.

Imagine a piece of graph paper with all the grid lines showing and 
also multiple 'normal' curves preprinted on it. Now place a few white 
rectangles to cover up the incorrect plots. It just loses something 
in the aesthetics.

I'm thinking the whole chart thing probably won't work for me since I 
can not preset the scale of each axis nor can I turn off the axis 
scale legends.

The best that I can come up with is determining the zero point on the 
form and then with pre-created plotting points that are kept 
offscreen, I'll just use MoveObjects to reposition them relative to 
the zero point using them as Cartesian coordinates manually. I'll 
stop at not trying to connect the dots.
