You need to copy and paste it to the command line, not as an OLE object. What you're doing is essentially automating exactly what you would type it if you had to do it all by hand. The column of concatenated results would be your inputs.

You can also use the 2DPLOT utility (free, see Download). After you load it you can start the 2Dplot LISP function with the definition of your math expression - e.g.:
The parameters are: the function fXY(v), from, to, step

When you pasted your selection, was the command line active, with he prompt "First point:"" ?

If you want to use a spline, use the following formula to plot points:
=CONCATENATE("POINT"," ",A1,",",B1) and then use them to plot a spline. Dave. |

Ok, I'm having a bit of of a problem. When using & or concantate, the cell is just an amalgamation of the two numbers, not seperated by a comma.
*edit: solved used the following formula: =CONCATENATE(A1,", ",B1)

Carl, it's not as simple... in fact it adds a few steps. But there is a slight difference in the outcome. This uses the same general idea you proposed, but instead of concatenating and creating just a set of coordinates I add POINT in front of them. So each line becomes POINT X,Y. That column is then pasted into the drawing to yield a set of plotted points. From there draw a spline thru them. What I noted was that the fit can be slightly different between this method and the PLINE method. Dave. |

"Try also simply plotting the points from Excel, and then fit a spline thru them."
Dave, how would you do this? I don't know of a simpler way than I described. I described using the "pline" command, but could substitute "spline" as well. |

Try also simply plotting the points from Excel, and then fit a spline thru them. The concatenate idea works to plot points too which can later be made "invisible" by changing their style. Compare the results with Carl's method above and keep the one you like best. Dave. Edited by heinsite - 26.Apr.2013 at 13:44 |
