Column chart

Column charts compare discrete amounts over time. Like bar charts, column charts show specific amounts—each column represents a clear end point.

• Start at zero baseline.
• Use light horizontal grid lines to help guide the eye across multiple columns.
• Figure out what the most important aspect of the chart is, and call attention to that.
• Choose logical increments.
• Avoid placing labels on an angle. If labels don’t fit, try horizontal bars instead.
• Don’t show more than 30 columns in a single chart.
