Let us learn a simple charting hack to create a thermo-meter chart in excel. This type of charts can be effective in communicating one data point, they can make excellent presentation slide or dashboard widget. What more, they are as simple to do as adding whipped cream to your latte. So lets begin:
1. First we will draw thermometer outline using excel’s drawing tools
This is the simplest part. We will create a thermometer outline by drawing a circle and a rounded rectangle. See the illustration to the right to understand. Next we will fill the circle with our favorite color. Not that excel presents us with may choices, but I choose the light green, the kind that you see on the Starbucks small size cups. Oh btw, learn how to tweak excel chart color limitation to add your own colors.
2. Create a one column bar chart to fit inside thermometer
Now we will create a one column bar to fit snugly inside our thermometer outline (see below illustration). We will start by creating a default bar chart for a single cell containing temperature (or customer experience index or sales actual vs. target % or no. of cats you have), Next we will remove grid lines, plot area backgrounds, x-axis, column borders, now it should look like just a bar. Then we will adjust gap width to 0 (select the bar, right click and goto format data series, click on the options tab and adjust gap width to 0), this will make sure that our one column occupies the entire plot area.
Then we will adjust the scale of y-axis so that whenever the temperature (or the number of cats) changes our bar height changes (instead of excel default behavior of adjusting plot area and thus often retaining the bar heights). Now we will remove the y-axis as well. Finally, change the bar color to light yellow, remove chart area fill color, border. That is all, we now have a shiny little bar that changes its height when you change the cell containing temperature.
3. Finally fit the chart inside the thermometer outline
This is simple drag and drop game where in we will drag our chart and drop it inside our thermometer outline created in step1. And we are done. Go ahead, celebrate, show it off, print shiny little thermometers on a paper and hang it in your cubicle.

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...
