Local Topcut Transition Model Plots

The Local Topcut Transition Model component has three child-plots to assist in analysis of the local topcut transition model.

1. Percent Metal Per Highest Grade Samples plot – Shows the highest grade samples within the dataset . The number of samples shown is equal to the value entered in the Number of highest samples to display field in the Local Topcut tab. The maximum number of samples that can be displayed on this graph is 30. You can interactively select the test grade by clicking on one of the bars. The grade is also highlighted on the Cumulative Metal plot in red. The Local Topcut Transition plot also updates to illustrate the topcut effect on that grade based on the other properties defined.

   Note: Setting a global topcut using the @ filter method impacts the Percent Metal Per Highest Grade Samples plot. The top 30 highest grades may all have been reset to the value you entered at the global topcut level.

2. Local Topcut Transition plot – Shows the topcut decay on a test grade based on the parameters set in the Local Topcut tab. The High grade dampening effect, Transition Factor and Transition range fields in the Local Topcut tab can be set by clicking and dragging the purple plus symbols on the plot. See Configure Local Topcut Transition Model Properties.
3. Cumulative Metal plot – Shows the contribution of each sample to the total metal sum. The samples at the top contribute more than the rest. Areas with significant breaks in the data points making up the trend line are considered to be extreme values outside the typical distribution. The test grade can be selected by clicking on one of the points. The grade is also highlighted in the percent metal plot, if displayed.

The plots can be displayed individually by selecting the plot component, or all together by selecting the Local Topcut Transition Model component in the Project Tree.
