Gaining real deep insight into your data is one thing, but then presenting that data in a logical, easy-to-understand manner that helps stakeholders understand what you’re trying to tell them is another. Sadly, some analysts fall into one or more of these pitfalls when visualizing their conclusions:
The secondary-axis fail. Here we can see a simple histogram with two metrics showing. One of them should clearly be displayed on a secondary axis.
The overwhelmed pie-chart fail. The choice of chart is important, and getting it wrong means that the meaning becomes obscured. Here we have a pie-chart with far too many segments to make it a meaningful visual:
The overly-complex 3D sales chart. Yes, it may look quite attractive on the page, but seriously, unless you’re trying to chart relief such as a mountain range, don’t bother!
The 2D stacker graph with one dominant series. Most people will notice only one of their series is shown – OK if you want to highlight only one series, but best to stick to a line graph for most multi-series comparisons.
- The messy line graph with markers left in. Again, like the overwhelmed pie-chart earlier, take those markers out because you’re helping to obscure what you’re trying to show!
