Make a Quick Thermometer Chart to Compare Targets and Actuals

Posted on December 17th, 2009 in Charts and Graphs - 36 comments

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.]
Target Vs Actual Charts Excel 4 - Thermometer charts
To make a thermometer chart, just follow these 5 simple steps.

1. Select the data and make a column chart

Sales Targets In Charts Sample Data - Thermometer charts

Select the data and insert a column chart.
Target Vs Actual Charts Excel 1 - Thermometer charts

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

Overlap Chart Series Excel - Thermometer charts
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:

    You’ll probably have some readers insist on bullet charts, which in my experience are no easier to read.

    Note on the case where actuals may exceed targets, the target has to be the second series in the chart, not the first, so it appears in front of the actual.

  2. Chandoo says:

    @Jon.. good point. And yes, readers are already saying bullets are the way to go. Atleast @dmgerbino said it on twitter: http://twitter.com/dmgerbino/status/6761754333

    But I feel the same as you did. Bullets need orientation to get started and not that easy to construct (here is a tutorial btw… http://chandoo.org/wp/2008/07/21/dashboard-bullet-graphs-excel/ )

    When you just have to compare 2 sets of values, a chart like above is good and easy enough.

    And yes, thank you for saying that data series order should be correct to show the target on top.

  3. Tony Rose says:

    I think bullet charts are a good alternative. I’m not a huge fan of the formatting that you used above where the outline is so thick.

    Another option would be to combine a line graph (plan/goal amounts) with the columns (actual) and select the option to remove the line. This leaves just the value (marker), which can be increased in size to leave only a line about the size of the bar. It’s an easy and cleaner way to show actual to plan/goal. Does that make sense?

  4. Jon Peltier says:

    Tony -

    I would use columns (or area) for goal, and lines and markers for actual.

  5. Matt says:

    What about if you go over the target? The chart doesn’t work so well then.

  6. The technique described today is a near bullet chart. As I stated early this morning on Twitter (link: http://bit.ly/4K3yPM ) , I am a fan of Stephen Few’s Bullet Graph.

    Hubert Urruttia and I started with Charlie Kyd’s method, but as Jon Peltier and Chandoo said, they are not easy to contruct. We moved onto prototyping with Fabrice Rimlinger’s SPARKLINES FOR EXCEL and now use XLCube’s (BonaVista) Micro Chart tool. Both of these tools allow you to create bullet charts just as easy as any Excel chart type.

    As far as reading and interpreting them, this chart type has been the easiest for us to present.

    There are many chart types. Today’s “Make a Quick Thermometer Chart to Compare Targets and Actuals” is fine for a start, but your ultimate goal should be to create Bullet Graphs. AS Stephen Few states in his overview, “The bullet graph was developed to replace the meters and gauges that are often used on dashboards. Its linear and no-frills design provides a rich display of data in a small space, which is essential on a dashboard. Like most meters and gauges, bullet graphs feature a single quantitative measure (for example, year-to-date revenue) along with complementary measures to enrich the meaning of the featured measure. Specifically, bullet graphs support the comparison of the featured measure to one or more related measures (for example, a target or the same measure at some point in the past, such as a year ago) and relate the featured measure to defined quantitative ranges that declare its qualitative state (for example, good, satisfactory, and poor). Its linear design not only gives it a small footprint, but also supports more efficient reading than radial meters.”

  7. Since @dmgerbino had to bring my name up I guess I should throw in my two cents.

    @dmgerbino and I have both implemented Bullet Charts with great success. What is most interesting about this fact is that we have had a harder time implementing Sparklines than Bullet Charts. The reason for this revolves around the simple fact of familiarity. I will explain. People look at a Sparkline and they think it is a really small Line Chart and it is not. People are familiar with Line Charts since they have been around since 1786 when they were created by William Playfair. Bullet Charts on the other hand are different so they almost demand an explanation. Because of this there was a lot of face time that was needed to explain these charts but once people got them they understood the concept. This is similar to when I introduced Cycle Plots http://bit.ly/87ydVG (Thank you @nbrgraphs!) or Horizon Charts http://bit.ly/6PVavj.

    Now about the Thermometer Charts… The first thing I want to address is Tony Rose’s statement. I totally agree that the outline on the chart is too think. It might come of as being a whole new series or a new variable. What I have done in instances like this is I have created a Bar Graph and Scatter Plot mixture. Then I have turned off the Data Series on the Scatter Plot and turned on the Horrizontal Error Bars on the Scatter Plot. The new horizontal line stands for the Plan and the Bar is the actual. The reason why I find this more useful is because this technique works if you have exceeded plan. Actually, I do not understand how Chandoo’s method would display the data if Plan is surpassed.

    This reminds me of another blog post that @dmgerbino, @Jon_Peltier, and myself commented on over a year ago. http://bit.ly/PNdO Actually, I talk about similar things in regards to familiarity to charting techniques.

    Hi Chandoo

    How do I increase the width of the bar chart and also make the long axis labels come in the same line?

    Thank you,

    Rajiv

  10. Hui... says:

    @Rajiv
    Select the outer part of the chart “Chart Area” and note the cursor will change to arrows
    drag the edges to what ever size you want
    You can hold the Alt key as you drag and the chart will snap to the cell boundaries

    Now click on the chart area inside the chart “Plot Area” and note that a box with small circles appears around it
    drag the circles on the edge of that box to suit
    You can hold the Alt key as you drag and the chart will snap to the cell boundaries

  11. Rajiv says:

    @ Hui
    Thank you for your comments. But my question was not for the “Plot Area” instead I wanted to know about how should I increase the width of the individual bar charts because with my data all the individual bars are coming to be thin and I want to make them appear broader.
    Thank You

  12. Hui... says:

    @Rajiv
    Right click on the Series you want to change and select Format Data Series
    Under Series Options goto Gap Width and decrease it to suit

  13. KH says:

    Thank you for the great chart and explanation!

  14. CL says:

    How do I show two amounts (Signed Revenue and Pipeline) as stacked within the Target amount?

  15. CL says:

    Chandoo – thanks for the quick response! What if I want the data label for the pipeline to be the actual pipeline value, not the signed rev + pipeline value? i.e. 15 instead of 55

    Thanks!

  16. Jimmy says:

    How would i do this in excel 2003?

  17. [...] Thermo-meter charts are very good to show how actual value compares with target (or budget). But how can we add another point for say Last Year value to the chart with out cluttering it. [...]

  18. Eric says:

    Hi Guys,
     
    As Matt said,
    “What if you if you go over the target?” 
    Is there a way to make it change color? or at least to show what the target  was?
    I am planning to use this with a “Forecasted vs Real” production chart but I do not know how  to show overproduction.
    Any clue?
    Thanks

  19. Jennifer says:

    How do I do this if I have 2 bars I want side-by-side?  ie 2012 Mean with 2012 benchmark overlapping and then 2013 mean with 2013 benchmark overlapping? I want the 2012 and 2012 mean bars sie by side to compare multiple categories. 

  20. Temma says:

    I have a problem in that my PM wants a chart that shows a stacked column (Labor and Expense) and then have the overall buget shown as a thermo.

    Everytime I try to do this, I either end up with all three being stacked or all of them being seperated. 

    Help?

    • Temma says:

      Or if someone knows how to only outline the top and sides of a chart series….then I would have this solved. (Make a stacked column with labor, expenses, and remaining budget, then clear the fill and outline only the top and sides.)  I just can’t figure out how to do that/ not sure if excel will let me only outline part of a chart series.

    Your home is valueble for me. Thanks!…

  22. Sandra says:

    I’ve created the thermometer chart as the Chandoo tutorial described. How do I move my columns closer together? I don’t want wider columns; I want to move my narrow columns closer together. Thank you!

  23. Abhinav says:

    Dear Elite members,
    could you please let me informed whether we could incorporate color formating in this thermometer approach i.e. if my actual performance is <Min then meter color sud go Red, in between min & target it sud change to Amber & target and above sud change to Green. pls advise. thanks,

    • Rick says:

      I think the only way to do that would be with VBA programming.

    • Hui... says:

      @Abhinav
      Yes, Simply use a stacked column chart, colored appropriately
      Or
      You may also want to read about Bullet Charts

      • Abhinav says:

        @ Hui,
        Could you pls demonstrate this with the help of an example.
        let’s have the below sample data

        Actual=12
        Min=10
        Target=15
        Max=20

        if Actual>=Min then bar color sud be Red
        in between Min & Target= Amber
        between target(inclusive) & Max = Green
        greater than or equal to Max= Blue

        Thanks in advance

        Abhi

  24. Rick says:

    Great blog post with awesome sample data. I’ve implemented two of the top “power tips” by changing the colour of the actual values, AND setting Actual to be 40% transparent. Looking good.

    I recently purchased the template bundle and love the ease of use – thank you!

    I would like to ask if it is possible to add an important ‘block’ to the dashboard to illustrate an important status for my executive team; ‘billing status’? (ie budget / amount billed) something like that?

    Thank you!

    • Chandoo says:

      @Cheif449.. Thanks for your purchase and kind words.

      You can add this easily to the dashboard. Follow below steps.

      1. Unprotect the dashboard worksheet.
      2. Add a text box (Insert > Drawing Shapes) to the dashboard
      3. Put any text inside it as per your need.
      4. Format it as needed.
      5. Protect the dashboard again.
