Question

State a few charts which we should not use with valid reasons?

Answer 1

Below here are few charts which we should avoid.

• 3D Charts: Visual representation of numbers in 3D charts will be skewed and it makes it difficult to compare and analyze.
• Pie Charts: Pie charts are not that much accurate as bar charts. In Pie charts, we have areas and angles to compare instead of length in a bar chart. Areas and angles cannot be analyzed with ease.
• Donut Charts: This is the same as Pie chart, but here, we have a hole in the middle to make it look like a donut. Due to that hole, we need to compare arc length with other arcs to analyze the values. Comparing arcs lengths is also a difficult task for our eyes.
