# Power Analysis of One-Sample Spearman Correlation: Plot

The Plot dialog provides options for controlling the plots that are output to illustrate the two and three-dimensional power by charts. The dialog also controls the vertical and horizontal rotation degrees for three-dimensional charts.

- Two-Dimensional Plot
- Provides options for controlling the two-dimensional power estimation versus charts. The
settings are disabled by default.
- Power estimation versus null hypothesis value
- When enabled, this optional setting controls the two-dimensional power by null value chart. The setting is disabled by default. When selected, this setting displays the chart.
- Power estimation versus alternative hypothesis value
- When enabled, this optional setting controls the two-dimensional power by alternative value chart. The setting is disabled by default. When selected, this setting displays the chart.
- Power estimation versus the difference between hypothesized values
- When enabled, this optional setting controls the two-dimensional power by difference between hypothesized values chart. The setting is disabled by default.
- Power estimation versus sample size (in pairs)
- When enabled, this optional setting controls the two-dimensional power by sample size chart. The
setting is disabled by default. When selected, this setting displays the chart.
- Plot range of sample size
- When selected, the lower and upper bound options are available. When no integer values are
specified for the Lower bound or Upper bound fields,
the default plot range is used.
- Lower bound
- Controls the lower bound for the two-dimensional power estimation by sample size chart. The value must be greater than or equal to 4, and cannot be greater than the Upper bound value.
- Upper bound
- Controls the upper bound for the two-dimensional power estimation by sample size chart. The value must be greater than the Lower bound value and cannot be greater than 5000.

- Three-Dimensional Plot
- Provides options for controlling the three-dimensional power estimation
versus charts. This setting is disabled by default.
- Power estimation versus sample size
- When selected, this setting enables the following options.
- on x-axis and the difference between hypothesized values on y-axis
- The optional setting controls the three-dimensional power by sample size (x -axis) and difference between hypothesized values (y-axis) chart. By default, the chart is suppressed. When specified, the chart displays.
- on y-axis and the difference between hypothesized values on x-axis
- The optional setting controls the three-dimensional power by sample size (y -axis) and difference between hypothesized values (x-axis) chart. By default, the chart is suppressed. When specified, the chart displays
- Plot range of sample size (in pairs)
- When selected, the lower and upper bound options are available. When no
integer values are specified for the Lower bound or Upper
bound fields, the default plot range is used.
- Lower bound
- Controls the lower bound for the three-dimensional power estimation by sample size chart. The value must be greater than or equal to 4, and cannot be greater than the Upper bound value.
- Upper bound
- Controls the upper bound for the three-dimensional power estimation by sample size chart. The value must be greater than the Lower bound value and cannot be greater than 5000.

- Power estimation versus null hypothesis value
- When selected, this setting enables the following options.
- on x-axis and alternative hypothesis value on y-axis
- The optional setting controls the three-dimensional power by null (x -axis) and alternative value (y-axis) chart. By default, the chart is suppressed. When specified, the chart displays.
- on y-axis and alternative hypothesis value on x-axis
- The optional setting controls the three-dimensional power by null (y-axis) and alternative value (x -axis) chart.. By default, the chart is suppressed. When specified, the chart displays.
- Vertical rotation
- The optional setting sets the vertical rotation degrees (clockwise from the left) for the three-dimensional chart. You can use the mouse to rotate the chart vertically. The setting takes effect when the three-dimensional plot is requested. The value must be a single integer value less than or equal to 359. The default value is 10.
- Horizontal rotation
- The optional setting sets the horizontal rotation degrees (clockwise from the front) for the three-dimensional chart. You can use the mouse to rotate the chart horizontally. The setting takes effect when the three-dimensional plot is requested. The value must be a single integer value less than or equal to 359. The default value is 325.
