To display a Data array from xarray using pyGMT's plotting function, follow these steps:

1. Import the necessary libraries:

import pygmt
import xarray as xr

1. Load the dataset from xarray:

ds = xr.open_dataset('data.nc')

1. Get the Data array from the dataset:

data_array = ds['data_variable']

1. Set the region and projection for the plot:

region = [xmin, xmax, ymin, ymax]
projection = 'your_projection_here'

1. Create the figure using pyGMT:

fig = pygmt.Figure()

1. Use the pygmt.grdimage() function to display the data array on the plot:

fig.grdimage(data_array, region=region, projection=projection, cmap='jet')

1. Customize the plot as needed using pyGMT's other plotting functions.

2. Show the plot:

fig.show()
