For every column chart that is done right, there are a dozen that get messed up. That is why lets talk about 5 simple rules for making awesome column charts.
Tip: Same rules apply for bar charts too. Rule #1: Start at zeroThe first rule is simple. Always start your column charts at zero. When looking at column (or bar) charts, our mind measures height of each column and compares. So, if a column starts at some arbitrary point instead of zero, it can mess with our perception of how each column compares with other. Don’t believe me. See yourself.Related: What is the most embarrassing charting mistake you made? Rule #2: Thou shall sortSort your columns in a meaningful order. For example, sort them by descending order (of column heights), alphabetical order or chronological order. This will make reading the chart easy.Rule #3: Slap a title on itGive your chart a meaningful, clear title. Few examples of good and bad titles shown below.Related: Using smart titles & legends in your charts Rule #4: Axis & Grid-lines vs. LabelsFor most charts you can use data labels instead of axis & grid-lines. This will keep the chart clean.If you choose to go with Axis and gridlines, then make sure they follow below guidelines.

If you use too many colors, you end up with a pig. People will then focus on all these colors, fonts instead of actual data.Few ways to add wow factor to your chart without messing it up:
