I have some .nc data that I use xarray to analyze. I wanted to overlay a shapefile on the plot and came across hv.plot which seems to have the interactive component I have been needing. However, when I tried to plot, it does not seem to work. Then I found the following thread: Why doesn't holoviews show histogram in Spyder? but could not get Maxime's answer to work and Sander's only partly works, however I have trouble "connecting to the local host" consistently. Does anyone have a solution?
ds_path = 'Z:/MODIS-LAADS-DAAC/'
ds_file = 'anom_2016_v1.nc'
ds_anom = xr.open_dataset(ds_path+ds_file)
x = ds_anom.Rrs_667.isel(time=0)
# create holoviews plot
hv_map = x.hvplot()
# display graph in browser
# a bokeh server is automatically started
bokeh_server = pn.Row(hv_map).show(port=12345)
# stop the bokeh server (when needed)
bokeh_server.stop()
However, I get this 95% of the time ERR_CONNECTION_REFUSED but occasionally get it to work and look like this (however I don't know why!!!) sample ocean data plot
