如何将图形列表发送到Bokeh vplot（）

Question

我正在用Python列表编程地建立一个plots列表，我想把它放到vplot函数，而不是当前使用的grid。文档中有子对象的显式枚举，但是我想知道是否可以获取一个figure对象的列表并将它们接收到vplot中，就像对grid对象所做的那样。在

channelPlots = []

for channel in myChannels :
    channelPlot = figure( width=1000, height=1000 , title=channel+ " Time Series" , x_axis_label = channel , y_axis_label = "TIME" )
    y           = sample.data['TIME' ]
    x           = sample.data[channel]
    channelPlot.scatter(x,y)
    channelPlots.append(channelPlot)

# With a grid it works  
#grid = GridPlot(children=[channelPlots], title="Time Series Channel Plots")

# with a vplot it breaks
grid = vplot( channelPlots )
save(grid)


Exception error is: expected an element of List(Instance(Widget)), got [[<bokeh.plotting.Figure object at 0x0000000009AA2128>, <bokeh.plotting.Figure object at 0x0000000006778CF8>, <bokeh.plotting.Figure object at 0

尝试下面两种方法都会引发相同的异常。。。在

Answer 1

您需要将列表显式地作为children参数传递：

grid = vplot(children=channelPlots)

或者，vplot接受子元素为*args：
