BennettS	Posted - 11/02/2018 : 08:05:58 AM Origin Ver. and Service Release (Select Help-->About Origin): Origin 2018b (64-bit) Operating System: Windows 7 What ist the correct way to get the result from the polyarea command into an usable form to write it into a cell? As far as I understood, the value of the "area" Output gets written in the result window, but is not accessible from the script window in an easy way. So either asking for the value with a simple area=; after running the command or using it in a similar form to one of these methods csetvalue col:=[Fit]Sheet1!col(A)[1] formula:="area"; [Fit]Sheet1!Cell(1,2) = area; does not work. Thanks for your help.

Hideo Fujii	Posted - 11/08/2018 : 11:55:49 AM Hi BennettS, Yes, this x-function sets the result to the specified (numeric) variable. If you want to print something to Result Log, you can redirect the destination by setting the "type.redirection" property to 16 like: type.redirection=16; //Output is redirected to Result Log type -a Area: $(myarea,.3); //or to print worksheet contents, run type.wks(Result); type.redirection=32768; //Output is set back to default https://www.originlab.com/doc/LabTalk/ref/type-obj Please try. --Hideo Fujii OriginLab
BennettS	Posted - 11/08/2018 : 04:51:25 AM Hi Hideo, your solution works perfectly, thank you. So the output from this X-function has to be stored immediately on execution and accessing the result log is not possible with Labtalk? As for the rd option, I found it as a general remark here https://www.originlab.com/doc/LabTalk/guide/XF-Input-and-Output and tested if it was usable in this case too.
Hideo Fujii	Posted - 11/07/2018 : 11:59:24 AM Hi BennettS, I don't see "rd" parameter in the polyarea x-function in: https://www.originlab.com/doc/X-Function/ref/polyarea As far as I tried, the following code worked: polyarea iy:=(col(1),col(2)) type:=abs area:=myarea; range rr=[Result]!col(1); rr[1]=myarea; Make sense? --Hideo Fujii OriginLab
BennettS	Posted - 11/07/2018 : 05:22:01 AM A bit more digging got me the the rd Option for X-functions, but polyarea iy:=(col(4),col(10)) type:=abs rd:=[Result]sheet1!; does not lead to any result, although I can't tell of that's a specific problem with only polyarea or more general.
