Excel Hints & Tips - Florence Nightingale & Excel
What on earth has Florence Nightingale got to do with Excel?
Florence Nightingale famously created a polar area diagram (a type of pie chart) in 1858 to show the cause of death in British military hospitals in the Crimean War. This highlighted the extent of preventable deaths (such as from typhus and cholera). The result was that the British government took action and commissioned Isambard Kingdom Brunel to design a new civilian hospital – reducing the death rate to just 1/10th of what it was before.
This important use of data visualisation shows how powerful charts (and especially pie charts) can be.
Hi, we are Happy
We are leading a movement to create happy, empowered and productive workplaces.
How can we help you and your people to find joy in at least 80% of your work?
But when should you use a pie chart?
Whether you are trying to fight for an important cause like Florence Nightingale, show where your website traffic comes from or just want to show your sales over the last year, pie charts can be really effective – big, bold and simple. But they can also be muddled, messy and confusing. What makes the difference is the data you are trying to chart. Not all data is suitable for all chart types and Pies are particularly vulnerable to having the wrong data used.
If we consider the table of data below that we have three rows of data organised into five columns. This data will not make a good pie chart!
If you try you might end up with a doughnut chart a bit like the one below… urgh!
Pie charts are better suited to one data series (a row or column of data), where you want to show in what proportions the data is divided.
Totals, or the rows or columns, give data that will be more appropriate to a good old Pie chart!
Excel can even add percentages!
Don’t forget, all of our IT training courses include two years of free access to our IT Helpline. The IT Helpline is staffed by our IT trainers, with support available by phone and email. You can contact our team as many times as you like about the material covered on your course.
