Imagine having two annoying little bloggers looking over your shoulder and trying to mess up with the chart you are making….
I am still waiting, go ahead, imagine…
Now come back, that is exactly what “The Chart DoctorBusters” is all about. It is a new series of posts on PHD and Jon Peltier where we take badly made charts, one at a time and suggest improvements, alternative visualization options and corrective measures.
For a doctor to be really good, he needs to have really sick people. In our case we need bad charts. I mean really bad ones with all those 23 colors or 17 pies or stressful extra grid lines or .. ok, you get the picture.
Here is what you should do:
- Upload your chart or excel workbook to a public site like skydrive.
- Now go to this google docs form and submit your charts
- (alternatively you can tweet us on @r1c1 or @Jon_Peltier)
Here is what Jon and I will do:
Every week we will take one of the really bad charts and post an entire article dissecting the problems and prescribing the treatment. We will take turns, so one week it will be Peltier and next week it will be me. We will also try to comment on each other’s treatment. With some luck, we should get other leading authorities in charting world to come and comment here.
Some rules to keep in mind:
- We are talking about charts here, not complicated dashboards or vibrating visualizations.
- As much as possible try to post the actual data associated with the chart and tell us clearly what you think the chart was trying to achieve.
- Remember, even parapsychologists get psyched.
- Have fun 🙂

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
