Module 2 · DAX and the numbers that matter Lesson 6 of 15
The three charts that are hard to get wrong
A column or bar chart for comparison, a line for time and a small table for detail. Almost every business question fits one of the three, and choosing correctly prevents most bad dashboards.
Worked example
A pie chart with nine slices answers nothing. The same data as a sorted bar chart makes the answer obvious in one glance, which is the only reason to draw a chart at all.
Your practice task
Rebuild one of your own charts as the correct type and write a sentence on what changed about what you noticed.
Do this before moving on. Reading a solution teaches the shape of it; typing it teaches you.
Key takeaway
A column or bar chart for comparison, a line for time and a small table for detail. Almost every business question fits one of the three, and choosing correctly prevents most bad dashboards.
