Unfortunately Windows Vista no longer comes with WinHlp32, which is used 
to show the help file for Graph. I am currently working on converting it 
to other formats. It is time consuming, but I hope to be finished when 
the next version of Graph is released.

But for now you can install WinHlp32 yourself under Windows Vista:

Did you try Zoom|Square?  I think it is ctrl-Q

Insert Tredline help

Hello.  I'm a new user to Graph.  My first experiment was to insert a point 
series and try to find its function.  I went to Insert Trendline and the only 
forms available for me to click were Linear, Polynomial and Moving average.  
Logarithmic, Power and Exponential were unclickable.  Does this program already 
know that those forms are not possible or is there something wrong with my 
version of Graph?  I thought my series was logarithmic, but I can't click on it 
to try.  Thanks.

Re: Insert Tredline help

I am not certain, but it may be that the number of points you entered did
not allow that to be determined.  For example, if you enter only 2 points it
makes not sense to ask for a quadratic regression, so it would not be
offered.

It is probably because at least one of the points has a negative 
x-coordinate, and the logarithmic function is only defined for positive 
values of x.

Re: Insert Tredline help

Thank you both for your help.  We figured it out.  There were no negative 
coordinates, but the first one was 0,0.  So I removed it and all the trendlines 
are now available.  It fits a "power" function perfectly.  Before I had you 
help I tried reversing all the x and y coordinates.  It fit the "Polynomial" 
function perfectly.  Is this true for all graph funtions?  That one function 
inherently has an opposite function when the coordinates are switched?  Thanks, 
still a math newbie.

Re: Insert Tredline help

I'm glad you were able to figure it out.
 
Yes, if you exchange the x & y coordinates the new points are described by the inverse relation.  For example, if the points are given by x-squared, exchanging x & y will yield the square-root function; if the points are from an exponential function, exchanging x & y will yield a logarithmic function.

Re: Insert Tredline help

Thanks a lot!  I really appreciate your help.  I was able to finally decifer 
one of the functions on my manual flight computer using this great program.
