Recently, I had to make a bunch of panel charts. After wrangling with Excel (and a tiny bit of VBA) to create them, I wondered if we are suffering needlessly by being too loyal to Excel. I switched to R and could create these panel charts in almost no time (well, first I had to learn how to pivot the data using dplyr). Today, let me share the experience.
The scenario – Visualize employee performance ratings
Around July, most companies in NZ have their employee performance reviews (or rem reviews). In August, all this review data is, well, reviewed so managers can decide whether any moderation (curve fitting) is needed and how much hike to offer. To help with this process, you need to first understand what proportion of staff are in each rating category. If you are head of a large company, then naturally, you want to know how this spread looks like at overall level as well as individual business group, branch levels, ie at various hierarchies.
The solution – Panel Charts
One quick and easy way to do this is by making lots of charts.
Enter Panel Charts.
Let’s say you have 80 branches, spread across 10 business groups. Each branch has different number of people. To understand if the ratings are normally spread in a branch, you can make a column chart showing number of people in each rating category. Then to see how this spread looks across the company, simply create 80 charts, one per branch.

80 Charts – that is not fun!!!
Tell me about it. You might need a strong cup of espresso and right mood for lots of copy pasting.
Or you could use some VBA to do the dirty work for you.
In either case, you are going to waste (and hate) that afternoon.
An alternative – use Sparklines
If you are not in the mood for manic copy pasting, then you could use sparklines to cheat. Once you make 80 sparklines, you can just move them around so they look like an 8×10 grid.
It is still a lot of work, but less annoying than creating 80 charts.
A better solution – use R
If you are familiar with programming (VBA/C or something else) you can quickly learn the basics of R and use simple code to convert raw data to elegant panel chart in almost no time.
OK, show me how.
Watch below video. I explain both Excel sparkline and R approaches. As the process is elaborate (especially the Excel one), I am using video format. See it below or on Chandoo.org channel.

Have you used R yet?
R is fun, interesting and challenging. If you have some free time, pick it up. It is free and offers heaps of possibilities for statistical analysis, data science, modeling, visualization, data cleanup and exploration. If you are looking for a book, I suggest R for Data Science by Hadley Wickham and Garret Grolemund.
If you are doing some R programming, please share your experiences and thoughts in comments.

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.
