Somnath's Excel Charts

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.

Soon after finishing the second Playfair chart, the one on Wheat Price and Wages, I searched the internet for additional charts made by him. I found a Bar chart circa 1786, which showed the Scottish export and import volumes with other countries. For me, the real thrill was to scroll by the list of the name of places long consigned to history books - Jersey Is, Greenland, Prussia, Denmark and Norway (together) and Flanders.  First, the original Playfair Barchart from Wikipedia,  Then, my version of it in Excel.  A couple of parting words:  Excel 2007 no longer support dots and lines as fillers for charts. Hence, the ribbed import chart is given a different color, Gold.  Normally, I'd use data point labels to construct the chart legends and other declarations given at the bottom of the chart. However, given Excel 2007' inability to automatically re-size labels to fit texts, I was forced to use text-boxes instead. 

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.

In one of his blogs excelcharts.com , Jorge Camoes talks about recreating the iconic "Playfair" charts. William Playfair (read more about him here), universally heralded as the "founder of the graphical method of statistics" is credited with inventing four types of diagrams. The Line graph and Bar chart in 1786, and the Pie chart and the Circle graph in 1801. In his post,  Excel charts meet William Playfair , Jorge includes pictures of the original Playfair England export and the prices of wheat and weekly wages charts alongside his recreated versions. He also lays down some rules for this challenge. "A single chart (no overlapping charts), no shapes/clipart to display data and, obviously, no Photoshop." The original Playfair trade-balance time-series chart from Wikipedia, and in below, my recreated version in Excel.

After creating my version of the Rugby World Cup Dashboard, it is time to redo their existing charts. My gripes were regarding the Treemap, the Stacked Bar and the Line charts, and here, I will attempt to offer easier, cleaner and more legible alternatives. My alternative to the Treemap Chart, The Stacked Bar chart,  and, the Line chart.

The Rugby World Cup Dashboard will live in my memory long for various reasons. Ever since I first received a mention of it in the pages of Bime Analytics , it haunted me with its collection of charts singularly inappropriate for their purpose. And what a collection of varied charts!! No two alike, it features a Treemap, an exploded Pie-chart, a Column chart, a Bar chart and a Line chart. Left to me, I'd have changed the colour of the theme, reduced the number of charts and designed the dashboard this way. The dashboard now includes more information, and all at the click of a button.

I often receive interesting ideas and suggestions from friends which forms the basis of some weird visualization. While personally, I prefer to keep my charts simple, effective and legible, I go creative listening to ideas from others. A friend of mine recently changed jobs. Before making his first presentation, he wrote to me about designing a chart which would WOW all his audience and help him to make a dramatic impact. The data was about units of products sold in each region and compared with similar data of competitors. Needless to mention, a simple column chart would have served his purpose well. But not to my friend. On his insistence, I drew up a dummy table, and served him the following. They look like abstract paintings. Right? Utterly amazed and curious, I thought of using this template on the Eurozone Debt data and came up with an even more wackier and colorful one. In both cases, the width of the lines are indicative of their values. I've ...
