WindRose PRO Help

The Calms tab of the Options button allows the user to specify if calms must be analysed, to set a speed threshold for such calms and to choose if they must be represented in the wind rose.

Alternatively, the user can specify if an inner circle must be drawn. In that case the wind rose will start from the border of the circle, not from a single central point. Sometimes the wind rose plot could be more clear using this option. The radius of the inner circle is specified as a percentage of the maximum radius of the wind rose; the possible values of the percentage are in the range [1,30]. This means that the maximum radius of the inner circle can be equal to 30% of the maximum radius of the wind rose. The user can also specify a color for the border of the inner circle and a color for filling the inner circle.
