Is there a way to have a chart float so that it is visible as I enter data on a very long spreadsheet?

Question

I am making a presentation to illustrate "normal distribution" (the bell curve).  As I enter random numbers into a very long spreadsheet, I want the viewers to see the chart take shape.  Is there a way to keep the chart visible as I move down the spreadsheet?
Thank you,

Answer 1

How about this for a rough idea (as in I did not try to make it look pretty):
Table 1 is a table of random numbers, as long a table as you want to use.
Table 2 uses NORMDIST to create the data points for the bell curve. The number of random numbers to include is given in cell D2, for which a stepper or slider would be a good choice.  The average and standard deviation for the chosen data points are created as follows:
average =AVERAGE(OFFSET(Table 1::A2,0,0,D2))
stddev =STDEV(OFFSET(Table 1::A2,0,0,D2))
Those two values are used in the NORMDIST functions in column B. I don't know if I used the function correctly but it sounds like you already know how to create a bell curve from the random numbers.
Nothing moves around so there is no scrolling required. Place the chart in view and use the slider/stepper to include more data points.
