Correcting Wiki Charts: Throughput Accounting

In one of his earlier posts, Jorge Camoes calls for changing bad charts in Wikipedia. Therein, he embeds several examples of charts, which can be easily considered "atrocious". Here, I'll attempt to correct the one titled "Throughput Accounting".

The embedded Wiki chart is a 3D horizontal cylinder chart and contains a long definition of Throughput accounting (T) and its structural components. The definition also includes two equations, T=Sales less TVC and NP=T less OE.

The 3D aspect of the chart serves no special purpose, and the cylindrical shape of the columns with the alternate blue and white bands seems intended for enhanced aesthetics. The columns are arranged without bearing in mind the relationship between the components, and the chart looks somewhat ragged overall.

I replaced the look of the chart from the 3D horizontal cylindrical to a "Waterfall" chart, using stacked columns. I also arranged the columns in reverse order to bring out the relationship between them that dispenses with quoting the two equations mentioned above.

My version of the Throughput Accounting chart is as follows:

Florence Nightingale Circumplex Chart

I was taken to the Florence Nightingale's Wiki page during a recent research, and one of the interesting things I noted was her contribution to statistics. It came to me as a pleasant surprise that she is credited with inventing the polar area diagram , or occasionally the Nightingale rose diagram, which is equivalent to a modern circular histogram. Following the completion of my project and in my weekend to spare, I devoted time to recreating the chart in Excel. It took a combination of Doughnut-Pie-and XY charts and close to four hours to finish it. The colours are a bit darker, the values are approximate and the labels differently oriented, yet the chart looks fairly close to the original as is shown by the picture below.

The Cricket Graphs: The Forgotten Chart

The fun of receiving feedback to blog posts is that one isn't quite sure what they might come up against. While mostly it provides fascinating discussions, insightful comments or explanatory questions, there is also the odd occasion when it throws up unusual requests. The other day I received an email in response to my post, The Cricket Graphs . The sender wanted me to create a "Partnership" chart, which would show the runs scored by the pair of batsmen for every wicket and the balls faced. I went searching for data on the Cricinfo website , and picked out the 3rd ODI between the South African and Australian cricket teams which was played out in Kingsmead, Durban on October 28, 2011. The Partnership details were taken from the page titled Partnerships Table and the total balls faced by individual batsmen from the Scorecard. Constructing the graphs was a somewhat tricky affair, with two potential bar charts in two axes representing Balls and Runs, which had me w...

The Playfair Charts: Wheat Price and Wages

After successfully recreating the Playfair trade-balance time-series chart , I took up the second chart shown in Jorge's post which is fancifully titled, "Chart showing at one view the price of the quarter of wheat and Wages of Labour by the week from The year 1565 to 1821." I left out the top arches. Comparatively, this was the easier chart. Staying true to Jorge' rules, I didn't use any shape or clipart objects in this chart. The big oval shaped object in the middle of the chart, which contains the title is actually a marker for a data point. The original Playfair Wheat price and Wages chart from Wikipedia, and underneath, is my version in Excel.
