This is the first installment of Chart Busters.
Chart busters is a new series of posts on PHD and Jon Peltier’s blog. We take turns to exterminate bad charts and associated evils. Although our proton packs are still not perfect, together we are confident of tackling most ghosts trapped in bad charts.
In this installment we take a look at Asset Allocation Chart that looks like it is hexed.
The bad chart
Our reader DMurphy submitted a poorly made asset allocation chart,
If you are looking for an early contender, here’s one which came in to my wife from her Pension company this week showing (or at least attempting to show) the make-up of her investments.
The above image is an excel reconstruction of even sadder looking chart.
What is wrong with it?
- Poor chart selection: Pie charts are good for 3-4 data elements. When we need to present 10 or so items, it is better to use a bar chart or a line chart.
- Not grouping and sorting the information: In the first chart which is displaying Asset Allocation is made from data that has 3 different series – Bonds, Equities and Other. But the chart shows everything in the same way, thus making it difficult to understand how assets are allocated to various classes of investment. Also, the data is not sorted in any meaningful order.
- Poor use of labels: The labels A,B,C … are non descriptive. They are also repeated on the other chart although they mean different things.
The Chart Busters’ Fix
Thanks to guest parachartanalyst Joe Mako, who contributed this fix:
I have taken Joe’s ideas and slightly modified them to create the below chart

Added Later: Readers Submitted Fixes
Submitted by Paulo Cesar Semblano da Costa:
- I think Paulo’s version manages to reduce chart clutter a bit more. Very good effort.
- You can download this version from here.
Submitted by Jeff Wier
- Jeff’s version is very good. Again, like Paulo, he managed to reduce the chart clutter bit more and made it look very slick.
- You can download this version from here.
What we have learned?
- Zombies are scary, even when they are looking like donuts.
- Always try to sort the data in some meaningful order before pushing it to charts
- Use a variation of panel chart or color the series sensibly to bring out key differences
- Try to avoid generic labels like 1,2,3 or A,B,C and instead use the actual values and category names
How would you have tackled this?
We dont know how open source the ghost busters were. But Chart Busters are 100% open source. Share your ideas and suggestions for improving this scary little chart to something that makes sense.

I’d suggest simply using the subtotal function and filtering the data using the Win/Loss column. You get the same results and the formula is more comprehensible.
@John
That is one option.
There are times however when you want to see the whole data table or a filtered subset and still want to produce summary reports against an unfiltered field.
Is there a particular reason why you are using a comma and the unary (–) operator for the second array in the SUMPRODUCT formula? It seems to work the same if you were to string the arrays together using the asterisk (*). The advantage is that SUMPRODUCT treats the entire string of arrays as a single array.
@Mathew
Your correct, There is no difference.
I thought it may have been easier to explain this method.
Is there a way to do this on a large set of data? As in ~100,000 rows? When I try I get an error because the formula becomes too long. It says the max length of a formula is 8,192 characters. Excel 2010.
How do I incorporate a specific text within a cell for the second array. For instance, – -(C7:C13=”Apple”)
when I chose a specific text the formula does not work.
@RB
I am not sure what is the issue as if I use the sample data in the post the following work fine
Count:
=SUMPRODUCT(SUBTOTAL(3,OFFSET(C7:C13,ROW(C7:C13)-MIN(ROW(C7:C13)),,1)), –(C7:C13=”L”))
Sum:
=SUMPRODUCT(SUBTOTAL(3,OFFSET(C7:C13,ROW(C7:C13)-MIN(ROW(C7:C13)),,1)),(C7:C13=”L”)*(D7:D13))
You may want to check that there are no leading or trailing spaces in your list of Apples
I should have given a better explanation. Heres my situation. I have a column with cells filled with names like Column 1, Column 2, Pier 1, Pier 2, etc. If the cell just contained Pier and searched for that it works. But because it has other characters in the cell its not recognizing the pier. So how can I extract specific characters of a string of text in this formula?
Hopefully this was a better explanation
Hello-
This formula works pretty well for me except that it slow down excel and prevents some of my macros from working. I was wondering if there was a way to program this in VBA so that excel isn’t always trying to recalculate it. I would like to use a push of a button to get it to run then paste in a cell.
Thanks!
I am trying to sum filtered data in a column, but would want to ignore the negative values in the column. How to go about doing this?
@Akshay
Why not just add a filter to that column to only show the values greater than zero?
The negative values are required for reporting purposes, but their effect on the total is distorting the required output. Please advise.
@Akshay
I’d suggest making a post in the Chandoo.org Forums

I have this working for counting and summing, however, I have a list and for the second array, I need a criteria. That is, I’m looking for b13:b200=”01.??.??” or =left((a1,2) or something like that. These types of criteria matches do not appear to work as I get a blank as a result.
Thanks!
@Bob
As your formula b13:b200=”01.??.??” looks like you are trying to check the first day of the month of the range
What about trying Day(B13:B200)=1
Hai Experts,
i understood this formula well and working fine in MS Excel 2013
but when the same am trying to place in google Spreadsheet it shows error as
“SUMPRODUCT has mismatched range sizes. Expected row count: 1. column count: 1. Actual row count: 2014, column count: 1.” and as a result #VALUE! Appears in cell.
Can anyone please help me how would i get it done in Google Spread sheet
or is there any other formula as a substitute for this.
Thank you very much.
thanks for providing this.. but why does excel keeps on prompting Circular referencing in cell D3?
@Vivek
I don’t know
I just downloaded the file and it is working fine and not showing that error
Goto the Formulas, Calculation Options Tab and check that Calculation is set to Automatic
What version of Excel and Windows are you using ?
I know that this forum is for MS Excel, but I am trying to help someone who is working in Google Sheets. The below formula works in Excel but Google Sheets returns:
“SUMPRODUCT has mismatched range sizes. Expected row count: 1. column count: 1. Actual row count: 39000, column count: 1.” and as a result #VALUE! Appears in cell.
This is the same problem asked by Srichirin above. Does anyone know if there is a formula for Google Sheets that will replicate what MS Excel does?
=SUMPRODUCT(SUBTOTAL(3,OFFSET($C$6:$C$39500,ROW($C$6:$C$39500)-MIN(ROW($C$6:$C$39500)),,1)),- -($C$6:$C$39500=H1),($D$6:$D$39500))
Trying to find a SUMPRODUCT formula that counts the word Closed by date for the last 7 days in a filtered list.
=COUNTIF(M:M,”>”&TODAY()-7) works ok for unfiltered count Column M contains Closure dates (blank if open) and Column L is Status Open or Closed

I used this formula and worked like a charm! But, now I’ve been requested to use it but adding not one but two criteria in the same formula. For instance the sum I was doing added negative and positive numbers. I’ve been asked to use the exact same formula but adding that only positive numbers were considered… any idea on how to do this?
How exactly do you do sum filtered cells when two criteria are need not just one?
Thank you so much brother literally I have been struggling since morning to get the sum of the filtered category, however, after reading your blog attentively i got my solution, so thanks a lot once again.
