Graphs Produced: Histogram of Rock Endpoint Locations
RocFall can plot histogram of the horizontal location of endpoints. The horizontal axis of the Horizontal Location of Rock End-points graph is the x-coordinate of the slope and the vertical axis is the number of rocks that ended in the bin at that location.
The plot "Endpoints" option under Graph menu
The generated Horizontal Location of Rock End-points histogram
By default, a graph first generated in RocFall is presented in a Split View format, with the slope shown in the lower half of the screen as a visual reference. The Split View mode can be toggled on or off at any time.

Graphs Produced: Envelope Graphs
Kinetic Energy (Total, Translational, and Rotational), Velocity and Bounce Height envelopes can be generated for RocFall analysis.
The Graph Envelope option under Graph menu
The Graph Envelope dialog
Total Kinetic Energy Envelope
The horizontal axis of the Total Kinetic Energy Envelope graph is the x-coordinate of the slope and the vertical axis is the maximum total kinetic energy that any rock reached while passing by that location. Locations on the slope that were not reached by any rocks will have a maximum total kinetic energy of zero.
The location of each vertex on the graph (where the energy is sampled) is determined by the number of bins. The width of each bin is calculated by dividing the width of the slope (maximum x-coordinate - minimum x-coordinate of the slope) by the number of bins (a.k.a. intervals, divisions). You can change the number of bins used to create the graph in the Project Settings dialog. Because some of the data used to create the slope-wide graphs is collected while the rocks are falling down the slope, the number of bins must be set before the analysis is computed.

Translational Kinetic Energy Envelope
The horizontal axis of the Translational Kinetic Energy Envelope graph is the x-coordinate of the slope and the vertical axis is the maximum translational kinetic energy that any rock reached while passing by that location. Locations on the slope that were not reached by any rocks will have a maximum translational kinetic energy of zero.
The location of each vertex on the graph (where the energy is sampled) is determined by the number of bins. The width of each bin is calculated by dividing the width of the slope (maximum x-coordinate - minimum x-coordinate of the slope) by the number of bins (a.k.a. intervals, divisions).

Rotational Kinetic Energy Envelope
The horizontal axis of the Rotational Kinetic Energy Envelope graph is the x-coordinate of the slope and the vertical axis is the maximum rotational kinetic energy that any rock reached while passing by that location. Locations on the slope that were not reached by any rocks will have a maximum rotational kinetic energy of zero.
The location of each vertex on the graph (where the energy is sampled) is determined by the number of bins.

Bounce Height Envelope
The horizontal axis of the Bounce Height Envelope graph is the x-coordinate of the slope and the vertical axis is the maximum bounce height that any rock reached while passing by that location. Locations on the slope that were not reached by any rocks will have a maximum bounce height of zero.
The location of each vertex on the graph (where the bounce height is sampled) is determined by the number of bins. The width of each bin is calculated by dividing the width of the slope (maximum x-coordinate - minimum x-coordinate of the slope) by the number of bins (a.k.a. intervals, divisions). You can change the number of bins used to create the graph in the Project Settings dialog. Because some of the data used to create the slope-wide graphs is collected while the rocks are falling down the slope, the number of bins must be set before the analysis is computed.

Translational Velocity Envelope
The horizontal axis of the Translational Velocity Envelope graph is the x-coordinate of the slope and the vertical axis is the maximum translational velocity that any rock reached while passing by that location. Locations on the slope that were not reached by any rocks will have a maximum translational velocity of zero.
The location of each vertex on the graph (where the translational velocity is sampled) is determined by the number of bins. The width of each bin is calculated by dividing the width of the slope (maximum x-coordinate - minimum x-coordinate of the slope) by the number of bins (a.k.a. intervals, divisions). You can change the number of bins used to create the graph in the Project Settings dialog.

Locations on the slope that were not reached by any rocks will have a maximum rotational velocity of zero.
The location of each vertex on the graph (where the rotational velocity is sampled) is determined by the number of bins. The width of each bin is calculated by dividing the width of the slope (maximum x-coordinate - minimum x-coordinate of the slope) by the number of bins (a.k.a. intervals, divisions).

Graphs Produced: Distribution Graph
Total, Translational and Rotational Kinetic Energy, Translational and Rotational Velocity, and Bounce Height distribution graphs can be generated in RocFall. The distribution graphs show the distribution of results at X locations (horizontal locations) along the slope.
The Graph Distribution dialog
A sample Total Kinetic Energy Distribution graph
A thick vertical line on the slope marks the X location of the data sampling. To sample data at other locations, simply click the left mouse button at the point of interest on the slope. The vertical line will move to this selected location, and the graph will be immediately updated to reflect the distribution at the location.

Graphs Produced: Barrier & Collector Graphs
For each barrier and data collector, the following histograms can be plotted for rocks that strike the barrier or pass through the collector: Total, Translational and Rotational Kinetic Energy, Translational and Rotational Velocity, and X or Y (horizontal or vertical) impact locations on the barrier.

Graphs Produced: Distribution Statistics
A summary of Graph Statistics is available for the Endpoint Locations, Distribution, and Barrier & Collector graphs in RocFall.
To display graph statistics, select Statistics from the Graph menu or the right-click menu on a graph. This will display a summary of statistics for the current graph, in its own dialog. The statistics may be copied to the clipboard by selecting the Copy button in the Statistics dialog. From the clipboard, the statistics can be pasted into a word processing program for report writing.
The Statistics option under Graph menu
The Distribution Statistics
A best fit distribution can also be found in the Statistics. For beta, triangular, and uniform distributions, all parameters specific to these distributions will be listed.
Distribution parameters are shown in the Statistics
