                Posted - 07/21/2009 : 05:58:02 AM   How can I access certain cells in a column?
  I can choose columns with "col(a)", is there something similiar for cells?
  Problem e.g.:
  Col(a) - Col(b) - Operation 1 - 6 - 1/6 3 - 7 - 3/7
  Thanks for help.

  You can use the index i which would represent row, as part of your formula, such as putting this as the formula for column C: Col(C)= (col(B)[i-1]-col(A)[i-1])/(col(B)[i]-col(A)[i])

                Posted - 07/22/2009 : 07:57:27 AM  Sorry, that thas a misleading example.
  I want to acces certain values in a column, which do not correspond to the same line.
  Col(a) - Col(b) - Operation 1 - 6 -  3 - 7 - (3-1)/(7-6)

                Posted - 07/21/2009 : 9:20:44 PM  Well, in the "Operation" column in your example, you want to calculate:
  Operation = Col(A) / Col(B)
  right? If so, you can use the "Set Column Value" dialog in Origin. Right-click the column and select "Set Column Value". Please read this for how to use it.
  Thanks Larry |

                Posted - 07/21/2009 : 09:16:46 AM  Ok, but how to automatically access the 2 cell then? (as represented in the 2 line)
  In Excel it is updated with drag and pop.

                Posted - 07/21/2009 : 08:01:09 AM  Use column index, like: col(a)[1], col(b)[2], etc.
