# Distribution Graphs

At any location along the slope, you can obtain a graph of the distribution of:

- Bounce Height
- Total Kinetic Energy
- Translational Kinetic Energy
- Rotational Kinetic Energy
- Translational Velocity
- Rotational Velocity

To plot a distribution graph:

- Select
**Graph Distribution**from the**Graphs**menu or from the toolbar. - The Distribution Graph dialog will appear.
- From the
**Data to Plot**drop-down list, select the data you wish to plot. - Specify the
**Number of Bins**along the length of the slope. - Click
**Plot Data**.

The distribution graphs show the distribution of results at X locations along the slope. The current location, X, is displayed in the graph title, and is also shown on the slope.

#### Notes:

- The bounce height is always measured from the main slope. Bounce heights are not measured from points created by slope roughness or crest loss.
- 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.
- If you click and hold the left mouse button on the slope, you can drag the vertical line marker along the slope, and the graph will be updated as the line moves.
- You can also move the sampling location with the left/right arrow keys or the mouse wheel (if your mouse has a mouse wheel).
- You can change the number of bins you see on the graph in the Chart Properties dialog. The Chart Properties dialog is available from the right-click menu in the graph view. Changing the number of bins does not change the number of Horizontal Locations specified earlier.

## Adjusting the Sampling Locations

The X locations of the data sampling are determined by the horizontal extent of the slope divided by the number of Horizontal Locations in the Distribution Graph dialog. In general, these X locations will not be round numbers.

To obtain round numbers for the X locations of the data sampling on the distribution graphs, you can:

- Adjust the number of Horizontal Locations, and/or
- Modify the total X extent of the slope (e.g. extend or shorten the first or last slope segment so that the total horizontal extent of the slope is a round number.)
