Custom HoverTool - show only non-hidden and non-muted data

[Itamar]

I have a line chart with multiple trends in it.
Each trend has corresponding point too.

I am aiming to get a hover tool like this:

I have achieved it using this code:

def add_tags_hover_tool(fig: figure, tags: List):
    tags_data = []
    for var in tags:
        if should_not_show(var):
            continue
        tags_data.append((var, '@{' + var + "}{0,0.000}"))
    hover = HoverTool(tooltips=[('date', '@timestamp{%Y-%m-%d %H:%M}')] + tags_data,
                      formatters={'@timestamp': 'datetime'},
                      mode='mouse')
    fig.add_tools(hover)

I want the hovertool to show non-hidden glyphs;

The HoverTool accepts a renderers argument, which is a list of the glyph renderers that you want to have hover-tool support.

When you create lines, scatters, or whatever, assign the output to a variable to access its glyph renderer, e.g.

r = p.line( ... )

You can then add logic to your function that builds up the tools to consistently specify which renderers you want to have hover support.
