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.

To avoid the helper column and the macro, I would transpose the data into the format shown above (Name, Year, Sales). Now I can show more than one year, I can summarize - I can do many more things with it. ASAP Utilities (http://www.asap-utilities.com) has a new experimental feature that can easily transpose the table into the correct format. Much easier in my opinion.

Of course with alternative data structure, we can easily setup a slicer based solution so that everything works like clockwork with even less work.
David, I was just about to post the same!
In Contextures site, I remember there's a post on how to do that. Clearly, the way data is layed out on the very beginning is critical to get the best results, and even you may thinkg the original layout is the best way, it is clearly not. And that kind of mistakes are the ones I love ! because it teaches and trains you to avoid them, and how to think on the data structure the next time.
Eventually, you get to that place when you "see" the structure on the moment the client tells you the request, and then, you realized you had an ephiphany, that glorious moment when data is no longer a mistery to you!!!
Rgds,
Chandoo,
If the goal is to see the list of customers who have not business from yearX, I would change the helper column formula to :
=IF(selYear="all",sum(C4:M4),sum(offset(C4:M4,,selyear-2002,1,columns(C4:M4)-selyear+2002)))This formula will sum the sales from Selected Year to 2012.

If you are already using a helper column and the combox box runs a macro after it changes, why not just adjust the macro and filter the source data?

I gotta say, it seems like you are giving 10 answers to 10 questions when your client REALLY wants to know is: "What is the last year "this" customer row had a non-zero Sales QTY?... You're missing the forest for the trees...
Change the helper column to:
=IFERROR(INDEX(tblSales[[#Headers],[Customer name]:[Sales 2012]],0,MATCH(9.99999999999999E+307,tblSales[[#This Row],[Customer name]:[Sales 2012]],1)),"NO SALES")
And yes, since I'm matching off of them for value, I would change the headers to straight "2002" instead of "Sales 2002" but you sort the table on the helper column and then and there you can answer all of your questions.
Hi thanks for this. Just can't figure out how you get the combo box to control the pivot table. Can you please advise?
Cheers
@Kevin.. You are welcome. To insert a combo box, go to Developer ribbon > Insert > form controls > combo box.
For more on various form controls and how to use them, please read this: http://chandoo.org/wp/2011/03/30/form-controls/
Thanks Chandoo. But I know how to insert a combobox, I was more referring to how does in control the year in the pivot table? Or is this obvious? I note that if I select the Selected Year from the PivotTable Field List it says "the field has no itens" whereas this would normally allow you to change the year??
Thanks again
worked it out thanks...
when =data!Q2 changes it changes the value in column N:N and then when you do a refreshall the pivottable vlaues get updated
Still not sure why PivotTable Field List says “the field has no itens"?? I created my own pivot table and could not repeat that.
Hi, I put the sales data in range(F5:P19) and added a column D with the title 'Last sales in year'. After that, in column D for each customer, the simple formula
=2000+MATCH(1000000,E5:P5)
will provide the last year in which that particular customer had any sales, which can than easily be managed by autofilter.
Somewhat longer but perhaps a bit more solid (with the column titles in row 4):
=RIGHT(INDEX($F$4:$P$19,1,MATCH(1000000,F5:P5)),4)
