ALL software version info

(this library, plus any other relevant software, e.g. bokeh, python, notebook, OS, browser, etc) Python version: 3.8.18 (default, Sep 11 2023, 13:20:55) [GCC 11.2.0] hvplot version: 0.9.0 numpy version: 1.24.3 pandas version: 1.5.3 xarray version: 0.20.0 plotly version: 5.18.0 matplotlib version: 3.7.2 bokeh version: 3.1.1

Description of expected behavior and the observed behavior

When trying to use hvplot explorer with a temporal xarray.DataArray like da.hvplot.explorer() with alternative backends like matplotlib and plotly

Complete, minimal, self-contained example code that reproduces the issue

import sys

import bokeh
import hvplot.xarray
import matplotlib
import matplotlib.pyplot as plt
import numpy as np
import pandas as pd
import plotly
import xarray as xr

print('Python version: ', sys.version)
print('hvplot version:', hvplot.__version__)
print('numpy version: ', np.__version__)
print('pandas version: ', pd.__version__)
print('xarray version: ', xr.__version__)
print('plotly version: ', plotly.__version__)
print('matplotlib version: ', matplotlib.__version__)
print('bokeh version:' , bokeh.__version__)

%matplotlib inline
da = xr.open_dataarray('test_hvplot.nc')

hvplot.extension('matplotlib')
a = da.hvplot.explorer()
a

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

Feb 22 '24 19:02 pedroaugustosmribeiro

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:
