Capping Strategy

Use this option to generate histogram, log probability, cumulative frequency, and general statistic charts that can help identify the impact capping your data at a certain threshold will have.

Follow these steps:

  1. On the ribbon, go to the Data tab, then click Open Data Source, then select the block model or database you want to analyse to load it into the Explorer Visibility column.

  2. Select the variable you want to use from the Data Explorer column, then right-click to select Grade Capping.

  3. Enter an initial Capping Value, or leave the default value of 1. You will also need to select the database field that represents the Length Variable if it is not automatically selected.

  4. Click the green check icon at the top of the Properties column to create the charts.

  5. Customise the charts by editing the parameters in the Properties column.
