Pie Chart Extension for Qlik Sense: What is a Pie Chart?
A Pie chart is a type of chart which displays information in a circular graph. It’s called “pie” because it’s divided into pieces, like the slices of a pie! While the whole volume of the Pie chart is equal to 100%, each portion or slice represents a fraction of the whole. Each slice also represents a different data category and the size of the slice is proportional to the quantity of data it represents.
What do you think about when you hear the word pie? Perhaps a delicious apple pie or pumpkin pie! Many people have a favourite when it comes to pie. And, if you work with data, Pie charts might be on your list of favourite visualisations! Though they’re certainly not as tasty as a freshly-baked pie, Pie charts do make data more digestible!
Pie charts demonstrate the numerical proportions of a data set in an easy-to-understand visual. And they’re really helpful when it comes to:
- Visualising how many data elements are included in the total. And the portions are shown in different colours too, for easy differentiation.
- Comparing the sizes of different pieces with each other. You can clearly see the largest to the smallest portions of the metric.
- Understanding the part-to-whole ratio to analyse the metric at a glance.
What are the Pie chart’s limitations?
Pie charts have their strengths, but they also have a few limitations you should be aware of.
- Comparing segments which vary only slightly in size is tricky.
- Determining the value of each portion without labels can take a long time for your audience.
- Showing change over time may require many pie charts and could complicate the visualisation.
- Unsuitable for large quantities of data. As the number of values shown increases, the size of each portion becomes smaller, making it difficult to view.
How do managers use the Pie chart in different industries?
Pie charts are a common visualisation in various industries around the world. Here are some examples.
