Is there a program to calculate fibonacci charts and their continuations

[TerabyteS]

I'd need a program able to take data and plot a trend graph, and it should be able to continue it to see the future trend. I've found some commercial programs but none work. Is there a free one?
I once saw some graphs with grey background and blue dots. What's the program that makes those?

1. Why is this in Programming?
2. iunno
3. You might speak about [url]http://www.nullular.com/grapher/main.php[/url], but it doesn't seem to support averaging points.

and 4. Do it yourself? :p

Excel can do that.

Also you should look for some older "Maple" versions that might be free by now, they also got it.

Also you can try to google for curve fitting.

Just use Excel, plot a scatter graph, add a trend line to it then edit the trend line options.

You can have it show the equation of the line of best fit and continue it however you want.

Excel will do everything you want.

Just in case you don't have access to Excel, you can try to find the same functionality in OpenOffice.Org Calc

That is called regression. [url=http://www.padowan.dk/graph/]Graph[/url] can do it.
