Explorer doesn't infer the right x/y/groupby values for gridded data about hvplot HOT 3 OPEN

I have setup a Jupyter Notebook for reproducing the issue with an example of my data at https://github.com/pedroaugustosmribeiro/test_hvplot

from hvplot.

Thanks @pedroaugustosmribeiro for reporting this issue and the example to reproduce it! I think what it comes down to is that the explorer doesn't pick nice defaults like .hvplot() does. When da.hvplot.image() is called, hvPlot infers x should be lon and y should be lat.

However, the explorer doesn't and ends up with the slightly awkward combination of time for x and lon for y.

With the Bokeh plotting library this combination sorts of work, or at least it doesn't break immediately. Forcing the explorer to be instantiated with better values, it works well with the matplotlib and plotly backends:
