How to change the transparency/opaqueness of a Matplotlib Table?
To change the transparency/opaqueness of a matplotlib table, we can atke following steps
Steps
Set the figure size and adjust the padding between and around the subplots.
Create a figure and a set of subplots.
Create a random dataset with 10×3 dimension.
Create a tuple of columns.
Get rid of the axis markers using axis('off').
Create a table with data and columns.
Iterate each cell of the table and change its transparency/opaqueness using set_alpha() method.
To display the figure, use Show() method.
Example
import numpy as np from matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True fig, axs = plt.subplots(1, 1) data = np.random.random((10, 3)) columns = ("Column I", "Column II", "Column III") axs.axis('off') the_table = axs.table(cellText=data, colLabels=columns, loc='center') for k, cell in the_table._cells.items(): cell.set_edgecolor('black') if k[0] == 0 or k[1] < 0: cell.set_text_props(weight='bold', color='w') cell.set_facecolor('red') cell.set_alpha(0.5) else: cell.set_facecolor(['green', 'yellow'][k[0] % 2]) cell.set_alpha(0.5) plt.show()
