我想更改散景圖的 x 軸。xrange = ["Marseille", "Lyon"]plot = figure(x_range=xrange)plotSource = ColumnDataSource(data=dict(x=xrange, y=[1, 2]))bars = VBar(x="x", top="y", width=0.1, fill_color="black")plot.add_glyph(plotSource, bars)handler = show(plot, notebook_handle=True)plot.x_range = ["Marseille", "Paris"] # how can i do thatpush_notebook(handle=handler)ValueError: expected an instance of type Range, got ['Marseille', 'Paris'] of type list我無法從列表中創建范圍，我該怎么辦？

您已經x_range在圖形構造函數中設置了，稍后您將嘗試設置它兩次。但是你應該使用plot.x_range.factors = ["Marseille", "Paris"]：
from bokeh.plotting import show, figure
from bokeh.models import ColumnDataSource, VBar
xrange = ["Marseille", "Lyon"]
plot = figure(x_range = xrange)
plotSource = ColumnDataSource(data = dict(x = xrange, y = [1, 2]))
bars = VBar(x = "x", top = "y", width = 0.1, fill_color = "black")
plot.add_glyph(plotSource, bars)
handler = show(plot, notebook_handle = True)
plot.x_range.factors = ["Marseille", "Paris"]
show(plot)
或者，也許這是您想要的更簡單的代碼（使用您的source）：
from bokeh.plotting import show, figure
from bokeh.models import ColumnDataSource
xrange = ["Marseille", "Lyon"]
p = figure(x_range = xrange)
source = ColumnDataSource(data = dict(x = xrange, y = [1, 2]))
bars = p.vbar(x = "x", top = "y", source = source, width = 0.1, fill_color = "black")
show(p)
