I have some data points on a scatter graph that I want do a line of best fit on. I'm doing Analysis->Fitting->Fit Linear and I get the required line solely within the range of my data points. However I need to extend this line in one direction - I think the proper term is extrapolate. This is very easy to do on Excel by just typing a number into the 'forecast' box. However I've spent quite a while trying to figure how to get Origin to do it, with no luck. Does anyone know how to do this? |

For Origin8.1, in the Linear Fit dialog, expand the tree node Fitted Curves Plot: X Data Type. Select Custom from Range combo box. You can define your desired minimum and maximum of the range in Min and Max edit boxes.
