A handwriting forming method, a handwriting forming apparatus, and an electronic device are provided. The method includes: determining a group of plurality of trajectory points according to a plurality of sampling points on a writing path on a working surface of a touch device, and obtaining trajectory information of each of the plurality of trajectory points, and the trajectory information including a coordinate, a flag bit and a pressure value; establishing a plurality of trajectory units in a raindrop shape corresponding to the plurality of trajectory points based on the trajectory information; determining a connection mode between trajectory units corresponding to adjacent trajectory points based on the trajectory information; and calculating connection points of the trajectory units according to the connection mode, and filling a polygon formed by the connection points of the trajectory units corresponding to the adjacent trajectory points, so as to form a handwriting for displaying.
