The nSpire from TI has such functionality, IIRC.

Both brands have that capability. They come at it from different angles. With the TI you edit stats lists then flick switches on the graph screen to turn on a data plot.

On the HPs, you enter your data into Edat matrix and use the stats function to find your regression/curve.

I don't know how to do screen shots on a TI, but it's pretty straight forward on a 50g.

You can find detailed instructions on page 12-32 and 18-13 of the HP 50g users guide.

Very respectfully,
