Bokeh Use Of Column Data Source And Box_select

I'm lost as to how to set up a Column Data Source so that I can select points from one graph and have the corresponding points highlighted in another graph. I am trying to learn mo

Solution 1:

My understanding is that the BooleanFilter, the IndexFilter and the GroupFilter can be used to filter the data in one of your plots before rendering. If you only want the second plot to respond to events in the first plot then you should just use gridplot as suggested in the comment. As long as the plots have the same ColumnDataSource they should be linked.

from bokeh.layouts import gridplot
from bokeh.models import ColumnDataSource
from bokeh.plotting import figure, show

source = ColumnDataSource(data=dict(x=[1, 2, 3, 4, 5], 
                                    y=[1, 2, 3, 4, 5], 
                                    z=[3, 5, 1, 6, 7]))

tools = ["box_select", "hover", "reset"]
p_0 = figure(plot_height=300, plot_width=300, tools=tools)
p_0.circle(x="x", y="y", size=10, hover_color="red", source=source)

p_1 = figure(plot_height=300, plot_width=300, tools=tools)
p_1.circle(x="x", y="z", size=10, hover_color="red", source=source)

show(gridplot([[p_0, p_1]]))
