Example of creating Excel Scatter charts.
Chart 1 in the following example is a default scatter chart:
Chart 2 is a scatter chart with straight lines and markers:
Chart 3 is a scatter chart with straight lines and no markers:
Chart 4 is a scatter chart with smooth lines and markers:
Chart 5 is a scatter chart with smooth lines and no markers:
