Bullet graphs provide an effective way to dashboard target vs. actual performance data, the bread and butter of corporate analytics.
Howmuchever effective they are, the sad truth is there is no one easy way to do them in excel. I have prepared a short tutorial that can make you a dashboard ninja without writing extensive formulas or installing unknown add-ins. So get out your shinobigatana and join me in a fresh excel sheet arena.
Before we create our first bullet graph, let us spend a few moments understanding these graphs. Stephen Few proposed bullet graphs as way to provide crisp view of “target vs. actual performance” numbers. Shown below is a sample bullet graph and how you would read it.
Read up more on this at PTS blog and on a Gauge chart that actually works.
Let us create your first bullet graph

Our technique of involves conditional formatting and simple formulas applied to a cell grid. Just follow these 4 easy steps:
Step 1: Prepare your data for charting
Since we are going to plot bullet graphs on a cell grid, we first need to normalize our data. I have chosen to plot each bullet graph on 20 cells in a row as shown in the raw grid shown to the right:
Assuming we have fictitious sales data like this:
You can normalize YTD sales figures using a simple formula like this : ROUND(YTD-sales/target*20,0)
Now that we have our data steaming hot, lets brew the graphs
Step 2: Lets make the raw grid formatted based on data
Now we will take the raw 20 cell grid in each row and conditionally format these cells so that we have background of the bullet graph drawn on them.
For eg. If the normalized sales data for Bad range is 7 and for OK Range is 15 then,
We will highlight first 7 cells lighter shade of gray, next 8 cells gray and last 5 cells with darker shade of gray.
I have shown the conditional formatting applied to these cells below:
When we are done, a sample row looks like this:
We have our cell grids ready now, lets shoot some bullets. 🙂
Step 3: Plot bullets on our graph canvas
Our final step involves print a bullet symbol (either – or + or | ) in each cell depending on one of the following conditions:
1. If the cell position (1,2,3 … 20) is equal to Year ago value and cell position is less than YTD value print a + symbol
2. If the cell position is equal to Year ago value and cell position is more than YTD value print a | symbol
3. If the cell position is less than YTD value print a –
4. Else print a blank
See the formula below:

Step 4: Show off your bullet graphs, awe your boss or colleagues, bask in your Ninja glory
Unfortunately, I cannot tell you how to do this. I can only teach you to be a Ninja, but you have to be one to charm people with your tactics. 🙂
Shown below is another variation you can try. Also, you can experiment with the symbols printed (instead of + – | you can try other ASCII characters, for more download the excel sheet containing bullet graph templates)

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.
[…] explains how to set up custom number formats with a wide array of […]
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
