how to use xarray directly as datasource

Hey,

i got a netcdf source over OPeNDAP which is quit big (about >100GB). I use xarray to load the data i need from it but dont know how to display this data with bokeh without transfering it into a pandas dataframe or a ColumnDataSource which would download all 100GBs if i understood it right. Could i use an xarray directly as a Bokeh Source and how?

Best regards and thanks,

Max

I will redirect you to other tools built on top or in parallel of bokeh
