Lets say you are responsible for sales of 100s of products (which belong to handful of categories). You are looking at sales of each product in last month & this month. And you want to understand whether sales are improving or declining by category. How would you do it?
Turns out, this is not a difficult problem. In fact, this question is asked every day & answered using Advances vs. Declines chart.
You may have seen this chart in financial newspapers or websites. Shown below, Advances vs. Declines chart tells us how many items have advanced & how many have declined.
When should you use Advances vs. Declines chart?
As you can see, advances vs. declines chart does not give low level details about actual movement of values. Instead, it gives you a sense of what is going on. Use it in below situations:
- To get a feel of how values have changed over time.
- When you are dealing with data that constantly changes (sales, number of customers, defects etc.)
Create Advances vs. Declines chart in Excel
You can easily create this chart in Excel from raw data. Just follow below tutorial.
Step 1: Get the data & arrange it
You need at least 4 columns of data – item, category, previous value, current value
Once we have these, calculate % change in 5th column. Arrange data like below:
Step 2: Calculate Category-wise summaries
First list all unique categories in a column. Then using COUNTIFS formula, calculate the number of products declining & advancing.
The formula to count number of products going down by more than 10% is,
=COUNTIFS(Sales[category], Category name, Sales[% change], “<10%”)
[Related: Introduction to Excel SUMIFS / COUNTIFS Formulas]
Step 3: Calculate % break-ups for the chart
Once all the numbers are calculated, you can easily calculate the % split.
NOTE: Make sure you negate the % values for declines. This will ensure that our chart shows stacked bars on both sides of axis.
Step 4: Create a stacked bar chart from this data
Once all the numbers are in place, just select them and create a stacked bar chart. Your output should look like below:
Step 5: Adjust chart series order if needed
You may notice that, our stacked chart bars are not in correct order. Excel would have plotted <10% and >10% series before <0% and >0% series. To fix this:
- Right click on the chart
- Go to Select Data
- Now, select the series area
- Using up / down buttons adjust the order of series
- Done!
See this demo to understand:
Step 6: Adjust the colors & format the chart
Unleash your creativity and format the chart as you see fit. Make sure you add legend (otherwise the chart becomes very difficult to read).
And you are done!

Hi Chandoo
As one of your students I have followed your detailed example through with great success. However, Excel is acting in an unexpected way and I wonder if you could take a look?
http://cid-95d070c79aef808e.office.live.com/self.aspx/.Public/Gantt%20Box%20Chart.xlsm
On my version, I have to type 40239 (Which equates to 2 Mar 2010) to get the chart to display 31 May 2010 (which should be 40329)!!??
Have I done something wrong or is Excel acting up?
Thx
Oli
PS Your example file in 2007 displays correctly.
Hi,
I like this idea a lot, but I agree the name is a little drab.
As an American I may just be seeing things, but to me the combination of lines and bars on your chart looks like a bunch of cricket bats.
Maybe you could work that into a catchier name. 🙂
Cheers!
Here is some code I use to keep the axis synched.
It may be useful to some of your readers
It is based on a comment I saw on Daily Dose of Excel.
Function SynchGanttAxis(Cname, lower, upper)
'Sets the X min and X max for Category axis
Application.Volatile
On Error Resume Next
'
'Top Horizontal Axis
With ActiveSheet.Shapes(Cname).Chart.Axes(xlCategory, 1)
.MinimumScale = lower
.MaximumScale = upper
End With
'Bottom Horizontal Axis
With ActiveSheet.Shapes(Cname).Chart.Axes(xlValue, 2)
.MinimumScale = lower
.MaximumScale = upper
End With
End Function
Function SynchVerticalAxis(Cname, lower, upper)
Application.Volatile
On Error Resume Next
' Excel 2007 only
'Right hand vertical axis
With ActiveSheet.Shapes(Cname).Chart.Axes(xlValue, 1)
.MinimumScale = 0
.MaximumScale = upper
End With
End Function
@Oli.. Can you check your file again.. I see 40329...
@Dave: Even I saw things.. the bars actually looked like lollipops. How about calling this lollipop chart - now that would be yummy and goes along the tradition of naming charts after eatables (bar, pie, donut...)
@Bob: Superb stuff... thanks for sharing 🙂
Hi Chandoo
This looks really good and I think it can also be applied to show project phases / milestones.
Question: Thinking further could this be amended to display a project lifecycle (Idea through to Implementation say 7 phases) on one bar / row? Just imagine 20 projects within a programme all on one chart one bar each showing their respective lifecycle stages i.e. on one page.
Idea: As the Gantt Box Chart this is quite intensive to set up re formatting etc how about the added extra of once you have completed this to "Save as template" i.e. saves the formatting and layout of the chart as a template so you can apply to future charts. Simple to do and will save the time formatting etc again and again and again.
Therefore tip: Click on your chart demo and then click on Save As template icon (2007) - edit file name and click on save. Ready to use / apply via Templates in Change Chart Type window.
Thanks and be very interested if the lifecycle question can be resolved
Mike
How embarrassing.
I was obviously suffering from numerical dyslexia. I was one of those days.
@Mike H: You can easily make this chart to work like a generic project lifecycle plan chart. All you have to do is,
1. in a separate sheet define the steps of lifecycle and various dates in a table (with 5 columns for each of the projects you have).
2. now use a control cell to input the project name you want to show in the chart
3. based on the input, use OFFSET Formulas to get the correct data
4. Rest is same as the tutorial above

Your solution is really smart but in the en Excel isn't meant to do stuff like this. I, as a former PM, always thought is was frustrating that you had to do stuff like this for something simple like a Gantt chart. So I built Tom's Planner. And would like to plug it here. I think it really solves the problem you are trying to solve in the most efficient way. Check out http://www.tomsplanner.com for a free account or play around with the demo.
Hi there,
Chandoo - this is really a very nice and helpfull chart - I adopted it, so I can report a forecast or the delay of a certain task (coming from my role as an auditor for projects).
One topic I´m currently struggeling with: I do have a project lasting for lets say 12 month. For a management reporting, I want to have kind of snapshot, lets say one month back and 2 month in the future. I tried with the offset formula, but failed. Any idea?
Thx
Lopi

Hi Chandoo - fantastic xls. One thing I can't figure out how to do is adjust the alignment of the vertical axis. I would like to left align so that I could indent to represent sub tasks. Can that be done? Or is there a better way?
I've been trying to work out if there's a way to show weekends on the graph. The closest thing I've got is to add them on a secondary axis, but then I haven't been able to keep both axis lined up together! Any ideas?
Following on from this - is it possible to show things like holidays?
