My guideline:

  • Columns to show trends over time. The shape mimics that of a line chart, you don’t need much space for the column labels (usually years, or months)

  • Columns for breakdowns. More horizontal space for complicated labels, and a stacked column is a more natural format than stacked bars.

  • Bars to rank things. The shape mimics a “top 10” top to bottom list, and you can make more space for labels that usually describe things

In this case: bars are better than columns.
