two variables in data view mapping

Markus_P — Thu, 09 Mar 2023 13:31:46 GMT

Hello

I am struggling with data view mapping. I want to get two variables (numbers) via two data fields in my project. Using single I have only managed to get one variable working. I have then tried using a table. That worked but there I have the problem that the table is field in order in with the user has inserted the values in the data field. I am reading the table in Order. But I need it distinct. I have also tried using a matrix, but I am unable to access the data in the code. With categorical I was not able to access it in the code. I have seen the documentation, but I am not fully understanding data view mapping.

Has anyone an idea?

Thanks

Hello

I hope I can help someone with this Information. I solved it via the Roles of Collums. I get the index, with this Index I know in which order the data was read in.

To get the Index I use:

let resultCY = dataView.table.columns.filter( (col) => col.roles["CY"])

I got this Information from:
