Gridded Data ¶
hvPlot provides one API to explore data of many different types. Previous sections have exclusively worked with tabular data stored in pandas (or pandas-like) DataFrames. The other most common type of data are n-dimensional arrays. hvPlot aims to eventually support different array libraries but for now focuses on
. XArray provides a convenient and very powerful wrapper to label the axis and coordinates of multi-dimensional (n-D) arrays. This user guide will cover how to leverage
to visualize and explore data of different dimensionality ranging from simple 1D data, to 2D image-like data, to multi-dimensional cubes of data.
For these examples we’ll use the North American air temperature dataset:
import numpy as np import xarray as xr import hvplot.xarray air_ds = xr.tutorial.open_dataset('air_temperature').load() air = air_ds.air air_ds
