Re: Plot problem. Hold on active between re-runs.

I think you missed the point of my suggestion.  I will explain it a bit 
more down there where the suggestion text is.

I was explaining how the "hold" function operated.  The example I gave 
was to help to understand the operation.  The "plot" and "hold on" in 
the actual case I did were inside a loop.  Repeating the "hold on" 
command does nothing good or bad so it can be repeated if that makes 
the code easier to do.
