pick_event_demo
选择事件演示您可以通过设置艺术家的“选择器”属性来启用拾取（例如，matplotlib Line2D，Text，Patch，Polygon，AxesImage等…） 选择器属性有多种含义 None - 此艺术家对象的选择功能已停用（默认） boolean - 如果为True，则启用拾取，如果鼠标事件在艺术家上方，艺术家将触发拾取事件 float - 如果选择器是一个数字，则它被解释为以点为单位的epsilon容差，如果事件的数据在鼠标事件的epsilon内，则艺术家将触发事件。 对于某些艺术家（如线条和补丁集合），艺术家可能会为生成的挑选事件提供其他数据，例如，挑选事件的epsilon中的数据索引 function - 如果选择器是可调用的，则它是用户提供的函数，用于确定艺术家是否被鼠标事件命中。 hit, props = picker(artist, mouseevent) 确定命中测试。 如果鼠标事件在艺术家上方，则返回hit = True，props是要添加到PickEvent属性的属性字典 通过设置“选取器”属性启用艺术家进行拾取后...
