Hướng dẫn dùng python arrow python
Add an arrow to the Axes. This draws an arrow from The x and y coordinates
of the arrow base. The length of the arrow along x and y direction. Width of full arrow tail. True if head is to be counted in calculating the length. Total width of the full arrow head. Length of arrow head. Draw the left-half, right-half, or full arrow. Fraction that the arrow is swept back (0 overhang means triangular shape). Can be negative or greater than one. If True, the head starts being drawn at coordinate 0 instead
of ending at coordinate 0. Property Description a filter function, which takes a (m, n, 3) float array and a dpi value, and returns a (m, n, 3) array and two offsets from the bottom left corner of the image unknown bool bool or None bool Patch or (Path, Transform) or None color color or None color or None bool str {'/', '\', '|', '-', '+', 'x', 'o', 'O', '.', '*'} bool object {'-', '--', '-.', ':', '', (offset, on-off-seq), ...} float or None None or bool or float or callable bool (scale: float, length: float, randomness: float) bool or None str bool float The created Notes The resulting arrow is affected by the Axes aspect ratio and limits. This may produce an arrow whose head is not square with its stem. To create an arrow whose head is square with its stem, use |
