Basic Tooltips creation without html

[leopoletti]

Hello,

It is more a feature request but I did not find how to create one.

It could be nice to be able to complete the hovertools by adding other column.
The best way I see could be in the same format as bokeh with a list of tuple:

TOOLTIPS = [
    ("index", "$index"),
    ("(x,y)", "($x, $y)"),
    ("desc", "@desc"),
]

that you get a basic funcy tooltips without to dive into html code

Hi @leopoletti,

I had a look at the code and I would propose the following API change:

1. Deprecation of hovertool_string
2. Usage of hovertool parameter as:
   • string: Use HTML for Hovertool
   • List of tuples: pass to tooltips ( as shown above)
   • True (default): use default tooltips with passed columns
   • False: Do not use tooltips

This feature however needs some development and refactoring. As a quickfix, you can go to pandas-bokeh/plot.py and comment out the following 2 lines:

Hope this helps you,

best Patrik

Hello @PatrikHlobil ,

It was not working since the code is based on string for hovertool_string and the new input is list of tuples.
Thus I change the code to this and its work as a first quick fix:

    if hovertool_string is not None:
        lstColumns=[tup[1] for tup in hovertool_string]
        lstColumns=[col.replace('@',"").replace('{',"").replace('}',"") for col in lstColumns]

        additional_columns=[col for col in lstColumns if col in df.columns ]

hi @leopoletti ,

yes this seems better for now. However, as I mentioned above the whole API should be changed.
