Chart Statistics

Overview of Chart Statistics

The Chart Statistics function allows you to integrate statistical information within the plot area of a chart. Grid values are represented by the chart, while the statistical values are portrayed using additional lines.

  • Each series in the chart can be assigned up to three statistical measures.
    • Standard Deviation
    • Average
    • Median
  • Once a statistical measure has been created, it can be customized in terms of line type, line color and line thickness.
