hover on a different - Bokeh Discourse

mkchanApr 01, 2016 #1

Hi,
Is there a way to associate the HoverTool to a different ColumnDataSource and on the same figure? I am trying to update the second data source which Hover will work on, after a CustomJS callback after selecting a group of points.

In this case I want hover to only work on variable s2.

TOOLS = ‘box_zoom,box_select,crosshair,resize,reset’

p = figure(plot_width=400, plot_height=400, tools=TOOLS)

p.add_tools(HoverTool())

p.circle(‘DF.L1.C1’, ‘DF.L1.C2’, color=‘color’, size=4, source=s, alpha=0.4)

s2 = ColumnDataSource(data=dict())

p.circle(x=“DF.L1.C1”, y=“DF.L1.C2”, size=6, color=“black”, alpha=1.0, source=s2)

s.callback = CustomJS(args=dict(s2=s2), code="""

…

“”")

show(p)

thanks very much,

-Mark

Sorry for the late reply, but you can always specify the renderers
option to the hover tool, which is not quite the same as what you
asked but may be helpful.

s2_circles = p.circle(x="DF.L1.C1", y="DF.L1.C2", size=6,

color=“black”, alpha=1.0, source=s2)
p.add_tools(HoverTool(tooltips=None, renderers=[s2_circles]))

Hope that helps,

Bird
