[英]How do you make the RangeTool in Bokeh select over multiple plots?
在參照
https://docs.bokeh.org/en/latest/docs/gallery/range_tool.html
您可以使用范圍工具控制主頂部圖表。
您可以修改它以便您可以選擇多個圖表嗎? 到目前為止,我嘗試顯示圖表,但只有與x_range
同步的圖表才是移動的圖表。 我嘗試傳遞一個列表,一個系列,但沒有任何效果。 有人可以幫忙嗎?
示例代碼:
import numpy as np
from bokeh.io import show
from bokeh.layouts import column
from bokeh.models import ColumnDataSource, RangeTool
from bokeh.plotting import figure
from bokeh.sampledata.stocks import AAPL, GOOG
from bokeh.layouts import gridplot
dates = np.array(AAPL['date'], dtype=np.datetime64)
source = ColumnDataSource(data=dict(date=dates, aapl=AAPL['adj_close'], goog=GOOG['adj_close']))
p1 = figure(plot_height=300, plot_width=800, tools="xpan", toolbar_location=None,
x_axis_type="datetime", x_axis_location="above",
background_fill_color="#efefef", x_range=(dates[1500], dates[2500]))
p1.line('date', 'aapl', source=source)
p1.yaxis.axis_label = 'Price'
p2 = figure(plot_height=300, plot_width=800, tools="xpan", toolbar_location=None,
x_axis_type="datetime", x_axis_location="above",
background_fill_color="#efefef", x_range=(dates[1500], dates[2500]))
p2.line('date', 'goog', source=source)
p2.yaxis.axis_label = 'Price'
p = gridplot([[p1,p2]])
select = figure(title="Drag the middle and edges of the selection box to change the range above",
plot_height=130, plot_width=1600, y_range=p1.y_range,
x_axis_type="datetime", y_axis_type=None,
tools="", toolbar_location=None, background_fill_color="#efefef")
range_tool = RangeTool(x_range=p1.x_range)
range_tool.overlay.fill_color = "navy"
range_tool.overlay.fill_alpha = 0.2
select.line('date', 'aapl', source=source)
select.line('date', 'goog', source=source)
select.ygrid.grid_line_color = None
select.add_tools(range_tool)
select.toolbar.active_multi = range_tool
show(column(p, select))
輸出:
您還必須配置所有要同步的圖,具有相同的范圍,例如
p2 = figure(..., x_range=p1.x_range)
