This is a Guest Post by Robert on Visualization Techniques for Excel KPI Dashboards.

This 6 Part Tutorial on Management Dashboards Teaches YOU:

Creating a Scrollable List View in Dashboard
Add Ability to Sort on Any KPI to the Dashboard
Highlight KPIs Based on Percentile
Add Microcharts to KPI Dashboards
Compare 2 KPIs in the Dashboards Using Form Controls
Show the Distribution of a KPI using Box Plots

In this final post we will learn how to add a box plot to show the distribution of values

The solution

The most common way in descriptive statistics to visualize the distribution of sets of numerical data is a box plot. But according to my experience in day to day business, most business people are not familiar with this type of visualization.
Therefore we try to create a simpler chart which is hopefully easier to understand:

The light grey bar visualizes the range of all values, the dark grey bar the range of the 10 items displayed on the management dashboard table. The cross shows the total average and – similar to the bullet graphs – the vertical line represents the target. This is less information than a real box whisker plot would provide, but I guess it will be easier to understand.

The implementation

Download the Excel KPI dashboard final workbook and read on how to create a simplified box plot.

  1. Let’s bring our ducks in a row first. Calculate all necessary data to be shown in the box plots: the minimum and maximum of the total data and of the 10 displayed items on the dashboard, the average and the target. The formulas are quite simple. You can find them in the downloaded workbook in calculation!AZ23:BE27.
  2. The basis of our visualization is a stacked bar chart with only one category and 4 data series:
    1. the invisible bar (the bar between 0 and the total minimum),
    2. the left light grey bar (the bar between the total minimum and the minimum of the displayed 10 items),
    3. the dark grey bar (the bar between the minimum and maximum of the 10 displayed values) and
    4. the right light grey bar (the bar between the maximum of the 10 displayed items and the total maximum).

    Again the formulas to calculate these values are quite simple (see calculation!BF23:BI27).

  3. Create a stacked bar chart and format the bars accordingly (no fill color and no border for the invisible bar, light and dark grey fill colors for the other bars).
  4. Add the average and the target values as additional series to the chart and change the chart type of these new series to XY scatter charts (X is the average / target value, Y is a dummy 1). Format the average as a cross (or whatever you choose) and use the error bars to format the target as a vertical line. The method of creating a combination chart of bars and XY scatters is pretty much the same we used in the 4th post of the KPI dashboard series (here).
  5. Remove or hide all unnecessary chart elements: no fill color and no border for plot or chart area; no line, tick marks etc. for the vertical axes, etc.
  6. Repeat steps 3 to 5 to create charts for all 5 KPI.
  7. Bring the charts to the dashboard, position them and add a caption to explain the chart elements.

That’s it. Play around with the new feature: change the sort criteria or sort order or scroll up and down the dashboard table and see how the new charts are changing.

Final Remark

This is a simplified version of box plot visualization and works only for data sets with positive values. Of course there is also a more sophisticated way of creating charts like this for any data (positive and negative values, i.e. bars crossing the vertical axis). This is a bit more complicated since you need 8 data series for the bar chart instead of 4 but the principle is exactly the same.

Our final KPI dashboard looks like this (click on it for a larger version):

With this last part I guess the time may have come to end the series about Excel Management KPI Dashboards here and to hand over the further development of this dashboard to the readers of Chandoo.org.
I do hope the series of 6 posts have been useful for your daily work and provided new ideas. Make sure you have downloaded the Excel KPI dashboard tutorial workbook
Thanks for all your comments and appreciations.
Last but not least: Chandoo, my friend, once more thank you so much for hosting my ideas at Chandoo.org.
Kind regards from Munich

Chandoo’s note

If not for Robert’s mail in August suggesting these wonderful ideas as posts in PHD, I would never have learned these things or shared them with you all. I am thankful to him for that.

Well, I am constantly trying to learn new dashboard techniques and I will try to share the worthy ones with you all. Meanwhile if you have a good idea for excel dashboards (or charts, techniques etc.) and would like to share with everyone, feel free to drop a comment or write to me. I will be *happy* to feature your ideas.

    Its possible to display up to 4 text values.

    Have a look at the screen shot of an example that I had posted way back at the EHA and figure out how its done !

  2. ruve1k says:

    With Excel 2010 you can use Conditional Formatting to apply custom number formats which can display text. (In older versions you can only modify text color and cell background color, but not number formats.) Using CF allows for an even larger number of different display values.

    Hey,
    Thanks, this helps. But how do you do it for multiple values where there is a huge amount of non repeating  text? 

  4. [...] Pivot Tables take tables of data and allow the user to summarise and consolidate the data at the same time. This is a great and very fast method of analysis but is restricted to handling mathematical functions on the value field resulting in numerical summaries. – read more [...]

  6. Jon Gali says:

    There is a very good way actually for handling text inside values area.
    First you create a special column on the very left side and call it ID, and put unique ID (numbers only), and then create a pivot table with:

    Row Labels and Column labels as you like, and in the Values labels use the unique ID number.

    Move the unique ID number (copy paste) somewhere to the right and use vlookup to load the data you need using the ID as reference.

    It is a bit longer way but for me it works perfectly to combine values as you like in any moment.

    hope helps.

    Regards,

    Jon

    Thank you! I finally understand pivot tables thanks to your clear, concise explanations and examples.

    Good Day. This is exactly what i have been looking for. However when i try it on my pivot table or even when i try to recreate this exercise using the sample worksheet, i get this error:

    "Microsoft Excel cannot use the number format you typed. Try using one of the built-in number formats."

  11. Letitgo says:

    I found an easy way to get text values in pivot table.

    I create an other worksheet in wich each cell has a formula that copy the pivot table. The trick is that the formula does a lookup for the numbers in the pivot table.

    The formula looks like that:
    =IF(ISNUMBER(table!A1);VLOOKUP(table!A1;Code!$A$1:$B$65;2);IF(ISBLANK(table!A1);" ";table!A1))

    Code is a worksheet where there is a liste of text /numbers correspondance.

    As a bonus The new sheet is easier to format

    Additional trick:
    In my case, i encoded differents codeid with a power(2, codeId-1) so that summing then is equivalent to concatenate them.

    1-A
    2-B
    4-C
    8-D

    yields :

    5 - AC
    14 - BCD

    Hi
    I want to ask if pivot can display dates in pivot field. As in a column i have customers and in row different items i want to know there last purchase date. anyone help in this??

  13. Tushar says:

    Hello Guys, Need your help
    I am doing some analysis of the cycle time of the product i.e how much time a product takes from manufacturing to the central warehouse.
    I have batch numbers for the product and against them i have to pull out the diff. dates
    Like the base date is from where the manufacturing start. So i have the batch number,against it's manuf. date. Now i have to pull out the date when it was quality released.
    I have the quality released data but the data have duplicates, like i will have two dates or may be three for the same batch. So my main objective is to pull out the date which is latest among them.

    BATCH NO. DATE of Mfg. DATE of Quality release
    A1 12/4/2014 (HERE I HAVE TO PULL value)

    Next Sheet
    BATCH NO. DATE of Quality Release
    A1 14/5/2014
    a2 23/5/2016
    A1 12/5/2014
    A1 13/6/2014

    From this sheet i have to pull up the latest date format of date here is dd/mm/yyy

    TIA
