Select a color in which the rose diagram should be displayed. Select this option to obtain a separate line in the rose diagram for every record (Y values) in the table. Select this option to connect the value of a record (Y values) with the value of the next record through a step-wise line. Select this option to connect the value of a record (Y values) with the value of the next record through a straight line. The name of the graph layer is visible in the Graph Management pane and in the legend of the graph window. Optionally, modify the name of this rose diagram. when you click an existing rose diagram with the right mouse button in the Graph Management pane, and select Graph Options from the context-sensitive menu.when you double-click an existing rose diagram in the Graph Management pane,.The option Rose Diagram is designed to display the output of the Segment direction histogram operation in graphical format. display options) of the selected rose diagram. Modify the name and/or the appearance (i.e. Thus the wind rose is a simple information display technique that has a multitude of uses.Graph Options - Rose diagram Graph window Windpower "farms" do extensive wind rose type studies prior to erecting their wind turbines. If wind rose data had been collected and used prior to the construction of San Francisco's famous windy Candlestick Park, the stadium could have been placed a few hundred yards to the north where it would have been protected from the prevailing westerly wind. Architects do, or should, use wind rose information for the siting of buildings and stadiums. Naval Oceanographic Office to get average winds for each ocean for each month of the year to help the create optimal sailing routes between ports. Sailors use wind rose information taken from the "Pilot Charts" by the U.S. The information provided by the wind rose can be applied to many and varied situations. A good example of a wind rose application is shown at the following URL. Wind speed data can be superimposed on each direction segment to indicate, for example, the average wind speed when the wind was blowing from that segment's direction and the maximum wind speed during the logging period. Typically the wind direction data is sorted into twelve equal arc segments, 30° each segment, in preparation for plotting a circular graph in which the radius of each of the twelve segments represents the percentage of time that the wind blew from each of the twelve 30° direction segments. The collected wind data is then sorted by wind direction so that the percentage of time that the wind was blowing from each direction can be determined. To create a wind rose, average wind direction and wind speed values are logged at a site, at short intervals, over a period of time, e.g. The wind rose is the time honored method of graphically presenting the wind conditions, direction and speed, over a period of time at a specific location.
