i visited this page ... here are a few comments
1. you have 9 scenarios on the page but, really ... you don't need that many
area above/below a point
area between or beyond 2 points
so ... i would reduce the number of basic graphs that you present
2. if you reduce 1 above .... then you can put BOTH the graphs AND the
dialogs that visitors fill in on the same page ...
let's say that the problem is ... area above or below a point ...
you have a graph shown ... with mythical point shown ... but, visitor in a
box ... enters their OWN z ... then you give back to them ... area below
AND the area above ... kill two birds with one stone
for area between or beyond two points .... same idea ...one graph ... 2 zs
they input ... then, you return area BETWEEN and area BEYOND ...
3. also ... you need a few more WORDS to people as to what to do ... now,
most will figure out you ENTER some z into the input box but ... it is not
obviously clear that you do that ... so TELL them how to use it ... can't hurt
there are a number of these routines available in other places such as ...
