To all our readers & friends from USA,
I wish you a happy, fun & safe 4th of July.
For the last 4th of July (2013), we (Jo, kids & I) were in USA. We went to Washington DC to meet up a few friends for that weekend. And we had one of the most memorable evenings of our lives when we went to national mall area in the evening to watch beautifully choreographed fireworks. Kids really loved the amazing display of fire-crackers and enthusiasm. (here is a pic, taken by Nakshu, our daughter)
While we all are back in India this time, it doesn’t mean we cant celebrate 4th of July. So I made some fireworks. In Excel of course.
Here is a little Excel animation I made for all of us.
4th of July Fireworks – Excel animation
First watch this quick demo (<15 secs)
Download the 4th of July fireworks workbook
I got the Excel fireworks idea very late in the evening. So the file is not very clean. But easy to understand and play with. Download it here.
How is this made?
Lets spare the detailed tutorial for another day. Here is a quick summary.
- Lets assume a fire work goes in a straight line at an arbitrary angle between 75 to 105 degrees (90 being vertical) to a random height.
- Lets assume the firework effect creates 40 spokes of a perfect circle whose radius grows as the firework explodes.
- So we create a scatter plot with lines & spokes.
- Thru VBA, we increase the length of line from 0% to 100%, thus creating firework shooting to sky effect.
- Then, we increase the radius of circle from 0% to 100% to create firework explosion effect.
- Finally we change the previous line height & circle radius back to 0% before showing next firework.
- At last, we toggle the display visibility of message (“Have a fun 4th of July”)
That is all. Here are a few previous examples that detail some of these techniques.
- Creating a spoke chart in Excel
- Happy Diwali, animated chart in Excel
- Hurricane Sandy explained in Excel with animated chart
- Showing & hiding a message – Customer service dashboard
So thats all for now. Enjoy your 4th of July weekend and lets meet Monday with something awesome.

Pivot Table will involve manual intervention; hence I prefer to use the 'countif remove duplicate trick' along with 'text sorting formula trick; then using the offset with len to name the final range for validation.
if using the pivot table, set the sort to Ascending, so the list in the validation cell comes back alphabetically.
Hui: Brillant neat idea.
Vipul: I am intrigued by what you are saying. Please is it possible to show us how it can be done, because as u said Hui's method requires user intervention.
Thks to PHD and all

Table names dont work directly inside Data validation.
You will have to define a name and point it to the table name and then use the name inside validation
Eg MyClient : Refers to :=Table1[Client]
And then in the list validation say = MyClient
Kieranz,
Pls download the sample here http://cid-e98339d969073094.skydrive.live.com/self.aspx/.Public/data-validation-unsorted-list-example.xls
Off course there are many other ways of doing the same and integrating the formulae in multiple columns into one.
Pls refer to column FGHI in that file. Cell G4 is where my validation is.
Vipul:
Many thks, will study it latter.

[...] to chandoo for the idea of getting unique list using Pivot tables. What we do is that create a pivot table [...]
@Vipul:
Thanks, that was awesome! 🙂
@Playercharlie Happy to hear that 🙂
Great contribution, Hui. Solved a problem of many years!
Thanks to you, A LOT
Hi Hui,
Greeting
hope you are doing well.
I'm interested to send you a private vba excel file which i need to show detail of pivot in new workbook instead of showing in same workbook as new sheet.
Please contact me on muhammed.ye@gmail.com
Best Regards
