Today, lets talk about an interesting extension to the idea of in-cell charts. Adding average or target markers to the chart.
Here is what we are going to create:

In-cell what? A quick re-cap
If you have never heard about in-cell charts, read this quick re-cap section.
In-cell charts are light weight charts generated to fit inside a single cell. Example in-cell charts are
- sparklines
- conditional formatting data bars
- bar charts generated with REPT formula.
First 2 options are very straight forward. It is (3) that is exciting because it opens up a lot of possibilities for us. See below, an introduction to in-cell charts.

For more on in-cell charts, refer to resources section at the end of this article.
In-cell charts with markers – how to?
Adding a marker (like average or target or last year value) can enhance your charts greatly and provide more context. Lets understand how to add marker symbols to in-cell charts.
For simplicity sake, assume that,
- A1 has data value
- B1 has average value
Now, the marker can be in 2 places.
- Inside the bar
- Outside the bar
The basic formula for generating an in-cell bar with markers is,
=IF(A1<B1, REPT("|", A1) & REPT(" ", B1-A1) & ".", REPT("|", B1) & "." & REPT("|", A1-B1))
How does this formula work?
First we check if we should print the marker outside the bar or inside the bar with IF(A1<B1 portion.
Then, if we need to print the marker outside,
REPT("|", A1) & REPT(" ", B1-A1) & "."
- Print | symbol A1 times
- Print SPACE (B1-A1) times
- Print the marker symbol
Else
REPT("|", B1) & "." & REPT("|", A1-B1)
- Print | symbol B1 times
- Print marker
- Print | symbol A1-B1 times

Do you make in-cell charts?
In-cell charts are one of my favorite charting techniques in Excel. I use them often in my reports or dashboards, when I want something quick & light-weight. They are easy to make & can look super awesome when you sprinkle a bit of conditional formatting on top.

You are right, Chandoo. I was playing with the colour numbers last week and some of them don't appear different from each other. Others are totally different from yours.
@Duncan
Each version of Excel, post 2003, renders colors slightly differently
Different language versions may also have different default color palettes
Hello in french
excel 2010
colo1 = couleur1 = black
[couleur1]; [couleur2]; etc..
@Hui, thank you very much again for this great post.
However - under Excel 2007, Hungarian version your solution does not work with color names. I've tried both English and Hungarian names, but drops an error message "not valid formats"
Do you have any idea how to solve this issue?
thanks in advance
@Andras
Without a Hungarian version of Excel 2003 I don't think I can assist
Have you tried using the colour numbers? I couldn't get the names to work (despite using an english version of excel). but it did work with the numbers though. I left out the "u" and was easily able to produce burgundy using [color9]
Here a possible solution: find an English version of Excel, write there the formats using English names, then open the file in the Hungarian version and see the translation.
In Excel 2007 I can't get the colour names to work e.g Sea Green but the numbers do e.g color3 - colour3 does not work so I must bow to the country that has stolen my language (ha ha!)
Hey chandoo, nice Tip!
Wouldn't be easier just apply some conditional formatting for negative numbers and another for positive numbers? Or there's some cases that you can't do that?
Unfortunately the TEXT function doesn't color the cell as number formatting does.
Hi Hui,
Great post Sir, love the new way of formatting with color numbers.
I am using 2007, and it leads me to the last color number 56.
Thanks Hui.

Thanks Hui - works a treat!
Thank you, very helpful.
Trying to figure out if it is possible to apply color only to a part of the cell?
E.g. I have a value formatted as Accounting with a currency symbol.
Those I find somewhat distracting though necessary. If I could make them less obtrusive by coloring them gray while the number would stay black, that would be great. Tried tinkering with the format string, but didn't get the desired result. Single color for complete cell value works, but coloring just part of it could not be achieved. Maybe somebody managed that?
Exactly what I was looking for - thank you!
colour in the Australian doesn't work - we have to go American and no problem.
I always thought is was 56 colours notice you have 57. Cool.
thanks
