Python Bokeh rollover color

Hi,

I use Python comprehensive list to display several charts and use HoverTool to display some data values.

[p.line(x='newindex', y='count', source=result.loc[result.index.year == i],\
color=next(colors),line_width=4,legend_label=str(i)) for i in unique_sorted_date]
hover_tool = HoverTool(tooltips='Date: @oldindex <br>  deces: @count')
p.add_tools(hover_tool)

I would like to highlight the line where I want to retrieve information (from tooltips). For instance, the selected line will be red and the others one greys. Is there an easy way to this?

By advance thank you
Cheers,
Olivier
