If your reports include hourly distribution of data like,
- Customer footfalls in your store
- Page views of your site
- Customer service calls to your toll free numbers
here is an interesting charting idea to show the data around the clock (literally)

Update: Visualization pros Jon Peltier and Jorge Camoes took a critical look at this, nearly fainted 😉 at the carnage of a familiar metaphor and posted their awesome reviews here:
Rock around the clock by Jon, he recommends a line chart over this for all the valid reasons
Charting around clock by Jorge, he suggests a neat looking 12 pointed radar chart as an alternative.
Both these are indeed fine examples of how shaking a familiar metaphor (analog clock) or way doing (usual bar chart for 24 hours) can bring a great discussion and excellent alternatives out of passionate people. Do read them 🙂
What you are seeing is essentially 2 bubble charts tweaked to look like wall-clocks with bubbles around the 12 positions.
This can be an interesting addition to your dashboards or daily report. Excited to find out how this is done? read on.
1. Get your data ready to plot it around the clock (circle)
Let us build the above graph using fictitious page view data for each of the 12 hours since midnight till noon. The data is shown aside.
In order to create the around the clock affect we need to plot each of these hourly values around a circle at 12 points. Now, without getting all mathematicky to scare you, lets try to come up with simple explanation to find all the 12 points around the circle:
Assuming the radius of clock or our chart circle is 100,
- Clock has 12 hour positions, thus each one is 30° (360°/12)
- The first point’s x value would be:
SIN(30°)*100 - and y value would be:
COS(30°)*100 - For each of the other 11 points, we just need to use the multiples of 30: 60, 90, 120, .., 360
- in excel spreadsheet you can find the values by
ROUND(SIN(RADIANS(hour*30))*100,0), ROUND(COS(RADIANS(hour*30))*100,0) - We have to convert the degrees to radians since SIN(), COS() accept only radians as inputs
Once we are done, the data should look like this:

2. Plot the Bubble Chart
This is the easy part, just select the cells containing x,y and page view values and insert new chart, select bubble as the chart type. Make sure you have mentioned the x,y, and bubble sizes in correct places.
The fun part begins after creating the chart, as the dimensions may be skewed and you may get egg like circle, so adjust the dimensions and your 12 hour clock view is ready to go.
Use the same process to create another clock for hours from noon till midnight and juxtapose them on that dashboard or report, send it across to your boss or team, let the conversation begin 😀
Download the template and play with it
Like this technique, why don’t you download the Data Around Clock – Charting Idea excel and play with it. Its available on the standard PAHF license (Poke Around, Have Fun)
Fun ways to enhance these charts:
- Overlay a clock diagram in the background
- Use sky color for the background, thus one clock has darker shades and other has brighter shades
- Bubbles themselves can be colored as Sun colors, bright orange to yellow and back to orange

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.
