Sampler

The Sampler option in RocPlane allows you to obtain the coordinates of points on:

• Cumulative Distribution (S-curve) Plots
• Sensitivity Plots

The Sampler is displayed as a vertical dotted line on a Cumulative Distribution plot, or as a horizontal line on Sensitivity plots.

To use the Sampler:

• SINGLE click the LEFT mouse button anywhere on the plot, and the sampler will jump to that location and display the results.
• Alternatively, press and HOLD the LEFT mouse button on the plot and you will see the double-arrow icon. Move the mouse in the directions of the arrow and the sampler will continuously display the values of points along the curve.

For example, plot the Cumulative Safety Factor distribution and move the Sampler to Safety Factor = 1 (actually it appears here by default). The Y coordinate displayed will be the Probability of Failure (i.e., the probability that the Safety Factor < 1).

The display of the Sampler can be turned on or off on the Chart menu or the right-click menu.
