How to convert an int to a date type Year Week number?

hello
i want to convert int to the year week number.
i am ploting result of a query that contain [“YearWeek”,“Performance”] as columns , in timeSeries Chart,
but the YearWeek column has an int type in the database , so it result an error when ploting because no time column.

thank you

Use the XY chart, rather than the time series chart?

In theory, with system.date.parse, the w format code, and probably at least the known year, you could turn a week number into an actual date object, but it’s probably not actually necessary or helpful to do so.

thank you for your response,

XY chart dosn't plot it like i need , it gives me this for more then two columns:

and in some case i have more than 10 columns , i don't know how to stacke them (i checked " stacked" for each serie )

yes i have the year too, so that's what i did for now.
my dataset is from a query response.

XY Stacked Bar Chart
this helped me a lot to figure out how stack the columns
