Python 在仪表板中加载带有预选值（如boxSelect）的plotly modebar

我正在

dash

中创建一个绘图仪，并尝试使用预选的动作值

boxSelect

创建模式栏。加载图形时，模式栏中没有预选值

这是我的密码：

dcc.Graph(
  id='scatter',
  className="chart-graph",
  config={
    "modeBarButtonsToRemove": ['toImage', 'zoom2d', 'zoomIn', 'zoomOut','autoScale2d','toggleSpikelines','hoverCompareCartesian', 'hoverClosestCartesian'],
    # This is the line of code I'm hoping initializes things, but it does not work...
    "select2d": True,
  },
)

---

明白了！配置布局时，添加以下参数：

layout = go.Layout(
  # ...
  clickmode='event+select',
  dragmode = 'lasso',
)
