Interactive Plotly Express plotting for xarray
pip install xarray_plotly
import xarray as xr import numpy as np import xarray_plotly # registers the accessor da = xr.DataArray( np.random.randn(100, 3).cumsum(axis=0), dims=["time", "city"], coords={"time": np.arange(100), "city": ["NYC", "LA", "Chicago"]}, ) # Accessor style fig = da.plotly.line() fig.show() # Or with xpx() for IDE code completion from xarray_plotly import xpx fig = xpx(da).line()
Why xpx()? The accessor (da.plotly) works but IDEs can't provide code completion for it. This is because xarray accessors are registered dynamically at runtime, making them invisible to static type checkers. The xpx() function provides the same functionality with full IDE support. This limitation could only be solved by xarray itself, if at all — it may be a fundamental Python limitation.
