I’m a bit new to datashader and interactive plots with Holoviews and Bokeh. In the census example, I am trying to figure out if we can customize the hover tool to show race with easting and northling. I modified this line to add in opts(tools[‘hover’]):
points = hv.Points(gv.Dataset(df, kdims=[‘easting’, ‘northing’], vdims=[‘race’]))
race = dynspread(datashade(points, color_key=color_key, element_type=gv.Image, aggregator=ds.count_cat(‘race’)).opts(tools=[‘hover’]))
gts.OSM() * race
however I only get the default eastling, northling coordinates along with RGBA. I would like to see race also. I have tried to mimic the census example with my own datasets and with the HoverTool, don’t seem to get past only displaying the x,y Points that we hand to datashader.
