Is it possible to make datashaded polygons without fill color?
I have my dataframe of polygons df
import geoviews as gv
from holoviews.operation.datashader import datashade
gv.extension(“bokeh”)
polys = gv.Polygons(df).opts(fill_alpha=0,line_color=“black”)
shaded = datashade(polys)
shaded
this shows the polygons with the default datashader colormap as fill color, and the resulting shaded object doesn’t accept fill_color and line_color arguments like Polygons do.
