Let’s learn how to create a color changing line chart using Excel. This is what we will create.

Looks interesting? Read on.
Why color changing line charts?
I will be honest. These charts offer no new information. The height of line already encodes the information we need. Color is merely an eye candy. But sometimes you may want some eye candy. If so, you can use this tutorial.
Let’s look at the data:
Let’s say we have some data for 3 months starting 1-SEP-2015 in a table like below. We need to add 3 extra columns – Before, Line & After as shown in the below picture.

What are these 3 columns?
- Before: This is value – 1
- Line: this is simply 1
- After: We first calculate the maximum possible value (let’s say 160) and then subtract value from it. ie 160-value.
Create a stacked area chart from Before, Line & After data:
Select all three columns (before, line & after) and create a stacked area chart.
This is what we get:

Fill plot area with red yellow green gradient

- Select plot area of the chart and fill it with a Red-Yellow-Green gradient (see below)

Fill colors in before, line & after series
- Select before series and fill white color
- Select after series and fill white color
- Select line series and fill it with no color (ie make it transparent)
This is what we get:

Adjust vertical axis maximum
to 160 (or any other value as used in your calculations earlier)
At this stage, our chart looks like this:

Clean up and format the chart:
- Adjust horizontal axis labels
- Set up a chart title
- Remove legend
Now, our color changing line chart is ready:

Would you use such a chart?
I find very few uses for this chart. Also, when creating this chart using area chart technique, we loose the ability to add grid lines (as they are covered by the white color filled areas).
What about you? Would you use color changing line charts? Please share your thoughts and suggestions in the comments section.

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
