Comparing values is one of the reasons why we make charts. So today I am going to teach you a handy little trick to make a thermometer like chart to compare targets with actuals. This type of chart is very useful when you have a bunch of sales targets and you want to measure how the performance has been. [Read excel theremometer charts for another option.]

To make a thermometer chart, just follow these 5 simple steps.
1. Select the data and make a column chart

Select the data and insert a column chart.

2. Select a chart data series and adjust “overlap” to “100% overlapped”

This will ensure that one series of the chart is 100% overlapped with another.

3. Format the target series so that only outline is shown
Select the series and set fill color to none, set the border color same as the fill color of “actual” series.

4. Remove grid lines and add data labels
Now our chart looks more like a thermometer.

5. Now go figure out why Acid Pops are struggling to sell
Yep, that is the fifth step. Go figure out why the targets are not met.
Bonus tip: If sometimes actual values are more than targets, then you should try different colors for target series’ border and actual series fill, like this:

While this works in a pinch, it clearly "lightens" the colors of the entire chart. Depending on where you use this, it will be blatantly obvious that you don't know what you are doing and present a poor looking graph.
Why not separate the data into different segments when charting and have as many colors as you have data points? You might have to create a new legend and/or repeat the chart in "invisible ink", but it would be cleaner and more consistent when new or updated data becomes available.
While I think I agree that doing it "properly" via a second series is preferable, I don't necessarily agree that making the entirety of the "future" (data, gridlines, and even the axis) semi-transparent is "poor looking". I think it could be seen as adding more emphasis to the "future-ness" of the forecast data.
In short, it's another tool for the toolbox, even if it's never needed.
Simply and clever 🙂
Quick & effective, cool. thanks.
I always use the dummy series.
Nice little trick, thanks very much!
Two sets of data better. Control is much better.
You can use the same chart next month to see what is actual and what is forecast.
To use this trick, I think grid lines has to be removed, that will make the graphic much more sharp.
to be honest, i dont understand why there is needed to do this way... in this case horizontal lines will be pale as well. then why a just can't change the color of the line partly???
Great tutorial. Thanks for the tutorial!
