Define the Statistics Region

Statistics are taken from a region defined on the curve by range boundaries, which are defined by two points on the selected curve.

  1. To select the minimum and maximum values of the region, do one of the following:
    1. Under Range, click the From/To radio buttons and enter a minimum and maximum value in each field, respectively.
    2. Select the minimum and maximum points on the curve from the graphics window.
      When you select from the graphics area, the X and Y values of each bounding point are displayed on the panel.
    3. Use the Find Point controls to define the range boundaries.
    Two vertical lines are displayed, representing the minimum and maximum values of the region.
  2. Once the range boundaries have been specified, click Calculate to compute the curve statistics for the defined area. Each time the range markers are moved, the statistics need to be re-calculated.
