Today is Diwali, the festival of lights. I wish you and your family a happy, bright and prosperous festive time. May your house shower with lots of light, laughter and love.
Diwali is one of my favorite festivals. It is a time when all family members get together, eat delicious food, laugh to hearts content and light up diyas (small oil lamps) to celebrate the victory of good over evil. This year, my kids (who are 6 yrs btw) are very excited about the festival. They are looking forward to lighting up diyas and crackers (fire works).
To celebrate the holiday, I made something for you.
An animated flower pot firework in Excel.
Here is a quick demo:

Click here to download the flower pot cracker chart. Click on the flower pot (triangle) to light up the fireworks.
How is this made?
Let’s keep it brief, after all, it’s festival time and I can’t sit in front of computer all day.
Flower pot:
- The flower pot sprinkles fire in parabolic shape.
- So we make 10 parabolas going to right and 10 to left (using the equation y=ax2 + bx + c)
- The parabolas stop midway because the fire dies. So we stop when y reaches RANDBETWEEN(30,90)% of maximum y.
- We then plot these 20 equations using XY scatter plot and color the lines differently.
- Using a simple VBA script, we increase the X value from o to 89 and feed the XY values to chart one step at a time
- This creates the flower pot fire cracker effect.
Tinkling diya:
- We make a single column bar chart and use light wick shape to fill the column
- We then increase the column height from 100 to 110 and then back to 100 in a loop
- This creates the effect of light going up and down, a la tinkling diya.

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.
