Did you know you can Calculate Pi by throwing Frozen Hotdogs !
Neither did I until recently.
But better than that is that you don’t need to go to the freezer to get the Hotdogs, you can do it all in Excel.
I recently wrote a post detailing how to develop a model to calculate Pi by simulating throwing hotdogs using Excel.
You can read about the Excel techniques used to make this simulation here: http://www.excelhero.com/blog/2014/11/calculate-pi-by-throwing-hotdogs.html

Hello...
In Power BI I have data that includes months by name only (e.g. May, April, December...)
I need to build charts etc. but i need the months to go chronologically... not alphabetically... I cannot seem to find the fix to this.... once again, my data does NOT have an actual date attached to it (like 02/01/2023)....only month names... can i use a helper table wher i id the month names as numbers 1 thru 12? and if so, how do i manage this to work for me ?
Thank you.

You need to setup an extra table to map each month name to a running number. A simple 12 row table like
Jan 1
Feb 2
Mar 3
..
Dec 12
Then create a relationship between this month table and your month column
Now, go to "table view" in Power BI and set the sort by column to month number for the month name column on this new table.
Finally, use the new table's month name whenever you need to refer to the month name in the visuals.
They will be chronologically arranged.
