Charting question: Line or Scatter or ... ?

[Robert Ameeti]

I was needing to brush up on my charting knowledge and came upon the 
following statement on pg 992 of the Panorama Handbook:

"On the other hand, in today's world of machines with 32 mb, 64 mb, 
128 mb or more memory there's not much reason to avoid using the more 
complex chart types."

Onward to my question...

I have a preprinted grid sheet with a preprinted 'normal' curve on it 
that I am needing to plot measured values onto. The values are scores 
over set amount of time and can be accomplished either with a Line 
Chart or a Scatter Diagram chart (and connecting the dots) to show 
the trend over time. The problem is that I need for the chart to be 
at a predetermined scale regardless of the values plotted due to the 
preprinted underlying grid and 'normal' curves.

ie. If a student's test scores were 50, 60, 65, & 70, these would 
typically plot either with an axis of 0 - 70 or perhaps a scale of 50 
- 70 (if I were to use a Non-Zero Axis) but what I am wanting is a 
scale from 0 - 100 as well as a preset typically longer axis for the 
time axis. I thought of having records for a second student as that 
would allow me to have the 2nd student with a 100 score so that I 
could force the size of the chart but that then caused a drop to zero 
for the 1st student for months that they have not yet tested.

Month	Score	Invisible Student
1	50	0
2	60
3	65
5	65
6	70
7
8
9
10		100

I also need for the axis legends to NOT appear since the preprinted 
chart appears beneath. I thought of choosing a white text attribute 
but the color applies to the line color and not the text color.

Any ideas?
