HoloViews

Hi @Ikajiro

I think there are two ways to go.

  • You can use a stream as shown below to react to mouse interaction with your plot.
  • You can embed the nglview inside the tooltip by creating a custom html tooltip as demonstrated in this example

An example of using a stream would be something like this.

import holoviews as hv
import pandas as pd
import panel as pn
from bokeh.models import HoverTool
from holoviews import streams

hv.extension('bokeh')

df = pd.DataFrame({
  "x": [1,2,3], "y": [1,2,3], "file_path": ["path1", "path2", "path3"]
})

TOOLTIPS = [("x","@x"), 
            ("y","@y"), 
            ("file_path","@file_path"), 
           ]

hover = HoverTool(tooltips=TOOLTIPS)

plot = hv.Scatter(df,kdims=["x"],vdims=["y"])
plot = plot.add_dimension("file_path",dim_pos=2,vdim=True,dim_val = "file_path")
plot = plot.opts(plot=dict(tools=[hover]))

pointer = streams.PointerXY(source=plot)


@pn.depends(pointer.param.x, pointer.param.y)
def file_view(x,y):
  if not x or not y:
    return "hover over a point"
  return (x,y)

pn.Column(
  plot, file_view
).servable()
