This menu is used for plotting data, like wind speeds, that are observed at angles around a circle. Once the data have been selected you can draw the graph by clicking on Finish, alternatively, additional options can be set by clicking the Next button.

Data Values

Specifies variates containing the data values. Select the name of the identifier for the data values from the list of available variates. You can double-click or use the button (for multiple selections) to enter the identifier name(s) into the Data Currently Selected for Plotting section. Alternatively, type the name of the identifier in directly and press return to enter it into the list.

Angles

Specifies a variate or factor containing the data values. If a variate is supplied, the observations are grouped for plotting into sectors based on the width (in degrees) and centres specified in the additional options. If a factor is supplied, its levels define the midpoints of the sectors and these must be in clockwise order. Select the name of the identifier for the data from the list of available variates and double-click to copy the name to the Data Currently Selected for Plotting section. Alternatively, type the name of the identifier in directly and press return to enter it into the list.
