📜  Bokeh-绘图工具

📅  最后修改于: 2020-11-09 05:14:28             🧑  作者: Mango

绘制散景图时，通常在图的右侧会出现一个工具栏。它包含一组默认工具。首先，可以通过Figure()函数的toolbar_location属性来配置工具栏的位置。此属性可以采用以下值之一-

  • “以上”
  • “下面”
  • “剩下”
  • “对”
  • “没有”

例如，以下语句将导致工具栏显示在图下方-

Fig = figure(toolbar_location = "below")

通过添加bokeh.models模块中定义的各种工具的要求，可以根据需要配置此工具栏。例如-

Fig.add_tools(WheelZoomTool())

这些工具可以分为以下类别-

  • 平移/拖动工具
  • 点击/点击工具
  • 滚动/捏工具
