The Chart button shows bar plots for different variables (average values for each direction, number of data for each direction, number of data for each data range, number of data for a given direction, number of data for a given data interval, etc.). The variable to show is chosen by means of a drop down list.
The charts can be copied and pasted in any other application. In MS Word you can paste the data, if you use only paste, or the image, if you use past as an image.
