How one would go about writing Performance Results to an Excel File?

Hi @pblack476 ,

you can use the "log" operator to get the Performance vector. Then you can either write the log directly to disc or you can later in your process chain use the "Log to Data" operator to get an example set.

Check the attached sample process for an example on how to use these two operators.

Best,
David

I would like to add to David_A's solution that you can also directly get an exampleset via the Performance to Data operator.
However there are no options and you will always simply get all selected criteria with their values, standard deviations and variances.

@scharpenberg @David_A

Thanks! I really don't need any customization done. Just getting it to Excel is fine and I can do the rest there, so I'll stick to scharpenberg's solution for starters.
