Spark Lines and Spark Bars

Miniature within-cell bar charts.

Spark lines and spark bars–miniature within-cell bar charts available in Excel 2010 and higher–are one of my favorite features of Excel.

I use spark lines to:

  • explore the patterns in my dataset;
  • see the highs and lows in my table;
  • think about what kinds of additional analyses I might want to conduct; and to
  • get ideas for more formal charts that could be shared with my colleagues or clients in a report or presentation.
