Formatting items on a graph

Summary

Need help with formatting dates and data on a graph

Content

Please help with me with converting week number to a correstponding date as shown in the attached document.

From week number (ex. 2-2021 is the second end of the week of the year) to the actual date corresponding to the  Friday of the week (1-8-2021).  

Also, how do I show the numbers on the graph (numbers of jobs opened in this case)?

Thank you so much in advance.....
