[Matplotlib-users] text color in matplotlib Table

[Alexandre V. <avo...@Ac...>]

Hi
I am trying to figure out how to change font color (as opposed to the fill color) in select cells in Table. Is there a way to do this?
Below is an example:

import matplotlib.pyplot as plt
import numpy as np
import pandas as pd
from matplotlib.table import Table
def main():
    data = pd.DataFrame(np.random.random((12,8)),
                columns=['A','B','C','D','E','F','G','H'])
    returnsTable(data)
    plt.show()

def returnsTable(data, fmt='{:.2f}/{:.1f}'):
    fig=plt.figure(figsize=(8,5))
    ax=plt.subplot(111)
    ax.set_axis_off()
    tb = Table(ax, bbox=[0,0,1,1])
    tb.auto_set_font_size(False)
    colorDict={-3:"#D00000",-2:"#FF5050",-1:"#FFBFBF",0:"#FFFFFF",1:"#D0FFD0",2:"#40FF40",3:"#00C000"}

    nrows, ncols = data.shape
    width, height = 1.0 / ncols, 1.0 / nrows

    dArray=data.values.reshape(np.product(data.shape))
    # mean&sigma..
    mean=np.average(dArray)
    sigma=np.std(dArray)

    # Add cells
    for (i,j), val in np.ndenumerate(data):
        z=(val-mean)/sigma
        idx = 0 if int(z)==0 else (max((int(z),-3)) if z<0 else min((int(z),3)))
        color = colorDict[idx]

## IS THERE  A WAY TO ALSO CHANGE FONT COLOR?
        tb.add_cell(i+1, j+1, width, height, text=fmt.format(val,z),
                    loc='center', facecolor=color)


    # Row labels in cells themselves
    # use -1 with edgecolor='none' for outside the grid
    for i, label in enumerate(data.index):
        tb.add_cell(i+1, 0, width*2, height, text=label, loc='right', facecolor='none')


    # Column Labels...
    for j, label in enumerate(data.columns):
        tb.add_cell(0, j+1, width, height/2, text=label, loc='center', facecolor='none')
    tb.set_fontsize(8)
    ax.add_table(tb)
    return fig

main()
