Last week, I asked my email newsletter readers to submit “one data analysis problem you are struggling with”. We called it BYOD – Bring your own data. More than 100 people have emailed various interesting (and often very difficult) problems. This week (between 16th of February to 20th of February), let’s take a look at some of these problems and solve them.
This problem is sent by Fiona.
Situation: Our commissions are growing way faster than revenues
Let’s say you are looking revenues & sales commissions of your company for last few years. The data looks like this:

And you want to highlight the fact that commissions are growing faster than revenues.
So you plot YoY growth rates for revenues & commissions.
Problem: The chart of YoY growth rates is not convincing
Take a look at the chart. It doesn’t convey the message that we want. At best it says “revenue growth is less than commission growth”

How to convey the message “Commission growth is a problem for us”?
Option 1. Use indexed charts
When comparing 2 sets of values (that are in different order of magnitudes) over time, we can use indexed charts. They can tell the story of how the values have changed over time clearly.
Here is the indexed chart for our data:

How to create this chart?
Simple. Just follow below steps.
- Calculate index values. Assume first year value for each series as 100 (so revenues = 100, commissions=100 in year 2010)
- For next year, calculate the value as this year value / first year value
- Plot these indexed values on a line chart
- Adjust the line chart axis minimum to 1 (or 100%) if all values are >1
- You are done
Option 2. Visualize ‘for every % in revenue growth, commission grows by…”
We can calculate what is the change in commission growth rate for every % growth in revenues & plot this. This will depict the situation in a powerful & dramatic fashion, like this:

How to create this chart?
Even simpler. Just do these steps:
- Calculate % values by dividing YoY commission growth with YoY revenue growth
- Plot this as a column chart
- Draw a line at 100%
- Add a text box at this line and write “Ideal” on it.
- You are done.

How would you present this information?
My favorite approach is to use indexed charts. They are designed for this exact purpose.
What about you? How would you visualize this kind of information? What charting techniques will you use to get your message across? Please share your inputs in the comments section.

I would like to see actual hash-tagged DM tweets go out to the specific information consumers. That would be an interesting way to communicate the key daily data to interested parties.
A Twitter-like secure application like Yammer might be a good fit with this.
For example, how about daily tweets to selected user groups (secure) that would display sales, bookings, cash receipts, cash disbursed and a second version that would show the same info for MTD, QTD or YTD figures.
@Dan, it would be great. I did not taught about implementing it on this dashboard because twitter is blocked to the whole intranet here. However, there's a discussion here about how can we send these tweets to blackberries (probably through e-mail) automatically. (I'd like to see this implemented on a jabber restricted network as well, but here it'll probably not happen)
The wrap-up versions you mentioned doesn't apply to my particular scenario, but on a sales tweetboard it would be a great tool indeed - choosing who will receive which message according to hashtags. I'll think on something, thanks for the advice. 🙂
(Ah, btw, I'm Fernando... 🙂 )
@Dan: That is a fun idea. Instead of tightly integrating twitter functionality with a dashboard, i think it would be cool if we have a "tweet this" button that users can click after selecting a range of cells. We can easily show a dialog with the concatenated output of the selected cells and ask user to edit the text and eventually "send to twitter".
For eg. you can select the annual sales figure cell and click on "tweet this" button upon which a dialog will show the value. Then you can pre-pend it something like "DM @boss look at our sales this year: "
@Aires.. thanks once again.
Wow it looks really good. Not sure though how much the tweet facility would help in real world project management, but certainly having a dashboard on a project should be a key deliverable when learning how to manage a project
The other use of this is during the software development life cycle especially when you have parallel streams of development and testing going on. Using a dashboard is a quick way for everyone on the team to see where the project is at and how it all fits together.

Hi Chandoo,
I purchased the project management toolkit but the dashboard shown above with the imbedded scroll bars. Is it included in the project pack??
Thanks
Sue
The gantt chart section of this dashboard is similar to one I have recently created: http://xlcalibre.com/hr-dashboard-gantt-chart-traffic-light-reportIt has a similar approach with scroll bars, but has a couple of additional features. I've tried to incorporate a traffic light report element, and also allow the timescale to adjusted so that can view it by days, weeks or months.I really like the other tables that you've incorporated, I may well try to replicate them to improve my version!
I am a monitoring and evaluation consultant in international development, and one of the services I offer is to help non-profits and foundations develop performance dashboards. I often advise them to develop dashboards for ongoing programs, rather than for one-time or pilot projects, because of the time involved. I am trying to find out from a few people how long it takes you to develop a project management dashboard, and to what extent the indicators vary from one project to the next.
