Hey guys, im new to origin and need some help pls
I got 2 Columns temperature col(a) and time col(b)
Temperature is rising unproportional.
I need a diagramm with y-Axe with Temperature/second and x-Axe with Temperature. So which heating rate i have at different temperature. |

Hi Rostger,
Could you show us more clearly about your question?
You have two columns dataset, column A is "Temperature", column B is "Time".
I am not sure the meaning of "Temperature/sekond". Is it "Temperature/Time"?
If so, you can:
1. Add new column
2. Highlight this column and right-click, and then click "Set Column Values..." to open the "Set Values" dialog.
3. In "Set Values" dialog, set the new column value= Col(A)/Col(B).
Please refer to the help page for "Set Column Values" tool:
http://www.originlab.com/doc/Origin-Help/Wks-SetColVal-QuickStart
4. Make sure the Column A is a "X" column, and new column "Temperature/Time" is a "Y" column.
High light the new column to choose the plot type you need to create.
Thanks
Jacqueline

No, thats not i wanted to say :D
If i write col(A)/Col(B) i will just get a division.
What i need is, col(A)difference between 2 and 3 is 0,2Kelvin and time difference is 25 seconds. Between 3 and 4 its again 0,2K but the time difference ist 19 seconds. It means that heating rate per second is higher from 3 to 4 (Where it is 0,2/19) and lower between 2 and 3 (0,2/25) |

Hi,
you will find DerivativeXY(col(c), col(a)) valuable  |

ok it looks pretty good and similar, but still not the same i cant heat 80K per second :D. I went this path Analysis: Mathematics: Differentiate and got this
 thanks by the way |

Now you've got your value in [seconds/Kelvin]. But it seems to be the better way to show your data.  |

Probably very easy, fitting...
