#How to plot joints on a rose diagram full
The method is convenient to deploy and capable of rapidly and accurately conducting rendering at the front end and updating the wind-rose chart in time and providing full support for development of the rose chart at the front end of a Web information system, and can be conveniently and rapidly connected to the Web information system needing rose chart drawing. The method comprises the steps that original wind factor data of different modes are processed in a unified mode and stored in a database through a data enhancing preprocessing engine process data analysis and assembly are conducted on wind-rose chart data obtained from the database by a wind-rose chart data service providing process according to a timing condition and wind-rose statistical data are provided for a front platform different display modes of the wind-rose chart are configured by a rose chart drawing assembly 'Wind Rose Chart', the display modes are configured to a Panel assembly of the ExtJs and are bound with a data set of the wind-rose chart after an ExtJs event mechanism asynchronously judges that the data arrive, the rose chart is updated. The invention provides a method for drawing a wind-rose chart based on the ExtJx.
