Hi,

i am new to origin (originpro 2015G)and i have a problem. i have 2 values(122) linked to time (hh:mm:ss). So i get 4 collums.
1: Temp
2: Timecode for Temp
3: Intesity
4: Timecode for Intensity

Temp is taken every second. Intensity 4 times during a second. is it possible to Plot Temp against Intensity. i want origin to link the Temp to the 4 related Intensity values.

i am still trying but i dont realy have a clue. any suggestions? thx in advance.

best regards jontem:

Hi,

The way I am thinking of is to split the column intensity into 4 columns and plot those four extracted columns versus Temp (X) so that you will have four intensity points corresponding to a single Template point at each second.

To do it, you can directly copy and paste the following code in Script Window and highlight all, press Enter to run:


// Suppose intensity column has Long Name "Intensity"
colsplit -r 0 irng:=col("Intensity") nrows:=4 rd:=[<input>]<input>; // Split Intensity columns into 4 columns
plotxy iy:=(?,5:8) plot:=201; // Plot splitted columns against Temp as Scatter plot


If this is not what you want, please proceed to explain in more details.

Thanks!

Regards!

Sean

Hi,

Sean's solution is to split the Y into 4 sub-Ys.
There is another alternatives that to generate a new X column based on the original one.
col("Temp") = pattern(col("Temp"), 4, 1); // Overwrite the original column
Or, add a new column and use Set Column Value with function body: pattern(col("Temp"), 4, 1). Then you can build a analysis template for new incoming data files.
