Data Classes definitions.

Here, you specify the discretisation of the rose plot.

The Circle Sector Size defines the directional intervals of the plot and the Centre Angle defines the centre angle of the first directional interval. As an example, let's say that you want to specify a rose plot with directional inter­vals 0^o-45^o, 45^o-90^o, ... etc. Then the Circle Sector Size must be specified as 45^o and the Centre Angle as 22.5^o.

The discretisation of the magnitude (e.g. speed or wave height) is defined by specifying the number of class delimeters and the corresponding delimeter values. To the right of the delimeter specification, the minimum and maximum value of the magnitude item in the selected time series file is given so as to make the selection easier.
The auto interpolation will automaticaly set the magnitude delimiters to the best fit.

In the bottom left corner, the colour palette can be chosen.
