Setting Certainty Bands

You can easily choose a set of certainty bands (levels) to display in the trend chart or create the own custom set.

  To change or define a set of certainty bands:

  1. In the trend chart menubar, choose Preferences, then Chart.

  2. Click the Chart Type tab.

  3. On the Chart Type tab, click the Certainty Bands button.

  4. The Percentiles dialog opens.

  5. Choose a set of certainty bands to display on the trend chart.

  6. To create the own set, choose Custom and enter a series of certainty bands, separated by commas.

  7. Click OK.

    The trend chart opens with the selected certainty bands. A legend is displayed on the right side of the trend chart indicating which levels are represented by which bands.

    If the legend does not include all bands, drag the top or the bottom of the trend chart to increase its height until all bands are displayed.
