Rail transit line station map drawing method based on hotspot adsorption

The invention provides a hot spot adsorption-based rail transit line station map drawing method. The drawing method specifically comprises the following steps of: determining a currently selected drawing object and a corresponding drawing type; if the connection type is the line segment connection type, hot spot information at the currently selected drawing object endpoint is collected, the drawing object is moved, in the moving process, connection information of each hot spot object in an adsorption area of the drawing object endpoint is detected in real time, hot spot objects in an unconnected state are screened out according to the connection information, and connection verification is conducted on the hot spot objects; determining a hotspot object connected with the drawing object endpoint, and establishing line segment connection between the drawing object endpoint and the hotspot object; and if the connection type is the combined connection type, determining to select the drawing object to be combined a
