NCL_table_2.pyΒΆ

This script illustrates the following concepts:
  • Drawing a table with headers

  • Filling table cells with a given color

  • Specifying the position of individual tables

See following URLs to see the reproduced NCL plot & script:

Import packages:

import matplotlib.pyplot as plt

Generate data:

# Set row headers (first column)
row_text = [
    "", "", "SLP_ERA40", "Tsfc_ERA40", "Prc_GPCP", "Prc 30S-30N_GPCP", "LW_ERS",
    "SW_ERS", "U300_ERA40", "Guess_BOGUS", "RH_NCEP", "LHFLX_ERA40",
    "TWP_ERA40", "CLDTOT_NCEP", "O3_NASA", "Q_JMA", "PBLH_JMA", "Omega_CAS"
]

# Set colors of row headers (first column)

    'lightgray', 'lightgray', 'lightgray', 'lightgray', 'lightgray',
    'lightgray', 'lightgray', 'lightgray', 'lightgray', 'lightgray',

# Set cell values (second and third column)

Plot:

# Create figure and axis
fig, ax = plt.subplots()

# Set axis aspect ratio
ax.set_aspect(2)

# Make axis spines invisible
fig.patch.set_visible(False)
ax.axis('off')

# Plot first table
table = ax.table(rowLabels=row_text,
                 rowColours=rowcolors,
                 rowLoc='center',
                 cellText=cell_text,
                 cellColours=colors,
                 cellLoc='center',
                 loc='center')

# Plot single-cell table in upper left of first table
plt.table(cellText=[['CAM METRICS']],
          cellColours=[['skyblue']],
          cellLoc='center',
          bbox=[-.694, .815, 0.694, 0.091])

# Give plot a tight layout
fig.tight_layout()

plt.show()
