A good dashboard must show important information at a glance and provide option to drill down for details.
Showing Top 10 (or bottom 10) lists in a dashboard is a good way to achieve this (see below).
Today we will learn an interesting technique to do this in Excel.
Lets assume you are the owner of ACME inc. and you want to show the performance of your products in a dashboard. But since you hate clutter (and love Coyote, your lone customer), you want to show the top 10 products by sales & orders and give an option to drill down if someone is interested.
Lets say your data looks like this:
Now, follow these simple steps.
- Select your data & insert a pivot table (tutorial here).
- Use product as the row label & sales as the value for pivot table.
- Now, sort the products by descending order of sales – See this:
- Comeback to dashboard and point to first 10 rows of the pivot report using cell references.
- Type view more in a cell beneath the top 10 and press CTRL+K (this opens the hyperlink dialog box).
- Just point to cell A1 in your pivot report worksheet. Click OK.
- Now, if you click on the view more link, you will jump to pivot report instantly. Pretty neat, eh?
- That is all. Go sell some Mouse Snare or Iron Bird Seed. Mr. Wile is at the counter.
Advantages of this technique:
Ardent readers of chandoo.org or dashboard practitioners usually rely on a sort & scroll technique similar to the one we discussed in KPI Dashboards post. But as you can see, using formulas & form controls is a tedious process. If you want to filter your source data based on a criteria (say top products by sales where refund rate is more than 3%) then your formulas will be awfully long and complicated.
This is where pivot tables shine. They are easy to setup. You can sort & filter pivot tables in multiple ways & then link the output to dashboard tables (or charts) with ease.

Do you show Top 10 values in Dashboards?
I use them all the time. You can see top 10 values in many of the dashboards I constructed or recommend. (here is 1,2,3). I think they are a great way to capture attention and encourage analysis. You can get top 10 values using either pivot tables like above or use formulas like large & small. You can even set up dynamic charts to show top 10 values. or use Conditional formatting to highlight top 10 values. I just love them.
What about you? Do you show top / bottom values in your dashboards? What techniques and ideas you follow. Please share using comments.

Do you have links to any sites that can provide free, large, test data sets. Both large in diversity and large in total number of rows.
Good question Ron. I suggest checking out kaggle.com, data.world or create your own with randbetween(). You can also get a complex business data-set from Microsoft Power BI website. It is contoso retail data.
Hi Chandoo,
I work with large data sets all the time (80-200MB files with 100Ks of rows and 20-40 columns) and I've taken a few steps to reduce the size (20-60MB) so they can better shared and work more quickly. These steps include: creating custom calculations in the pivot instead of having additional data columns, deleting the data tab and saving as an xlsb. I've even tried indexmatch instead of vlookup--although I'm not sure that saved much. Are there any other tricks to further reduce the file size? thanks, Steve
Hi Steve,
Good tips on how to reduce the file size and / or process time. Another thing I would definitely try is to use Data Model to load the data rather than keep it in the file. You would be,
1. connect to source data file thru Power Query
2. filter away any columns / rows that are not needed
3. load the data to model
4. make pivots from it
This would reduce the file size while providing all the answers you need.
Give it a try. See this video for some help - https://www.youtube.com/watch?v=5u7bpysO3FQ
Normally when Excel processes data it utilizes all four cores on a processor. Is it true that Excel reduces to only using two cores When calculating tables? Same issue if there were two cores present, it would reduce to one in a table?
I ask because, I have personally noticed when i use tables the data is much slower than if I would have filtered it. I like tables for obvious reasons when working with datasets. Is this true.
John:
I don't know if it is true that Excel Table processing only uses 2 threads/cores, but it is entirely possible. The program has to be enabled to handle multiple parallel threads. Excel Lists/Tables were added long ago, at a time when 2 processes was a reasonable upper limit. And, it could be that there simply is no way to program table processing to use more than 2 threads at a time...
When I've got a large data set, I will set my Excel priority to High thru Task Manager to allow it to use more available processing. Never use RealTime priority or you're completely locked up until Excel finishes.
That is a good tip Jen...
