實例

from __future__ import print_function
from matplotlib.font_manager import FontProperties
import matplotlib.pyplot as plt

# text = "TEXT"
ax = plt.subplot(331)
ax.axis([-2,2,-2,2])
ax.text(0,0, 'TEXT')
ax.set_title("(0,0)")

ax = plt.subplot(332)
ax.axis([-2,2,-2,2])
ax.text(0,0, 'TEXT',withdash=True)
ax.set_title("withdash=True")

ax = plt.subplot(333)
ax.axis([-2,2,-2,2])
ax.text(0,0,'TEXT',ha="center",size=20,bbox=dict(boxstyle="circle", fc="b", ec="r"))

ax = plt.subplot(335)
ax.axis([-2,2,-2,2])
ax.text(0,0,'TEXT',size=15, rotation=30.,ha="center", va="center",bbox=dict(boxstyle="round",ec=(1., 0.5, 0.5),fc=(1., 0.8, 0.8)))
ax.set_title("srotation=30")


ax = plt.subplot(336)
ax.axis([-2,2,-2,2])
ax.text(0,0,'TEXT',size=15, rotation=-30.,ha="right", va="top",bbox=dict(boxstyle="square",ec=(1., 0.5, 0.5),fc=(1., 0.8, 0.8)))
ax.set_title("rotation=-30")

ax = plt.subplot(337)
ax.axis([-2,2,-2,2])

fp = FontProperties()
fp.set_size('xx-large')
fp.set_family('serif')
fp.set_variant('small-caps')
fp.set_weight('bold')
fp.set_style('italic')

ax.text(0,0,'TEXT',fontproperties=fp)
ax.set_title("fontproperties=fp")

ax = plt.subplot(338)
ax.axis([-2,2,-2,2])
ax.text(0,0,'TEXT',size=15,zorder=2)
ax.text(0,0.2,'TEXT',size=15,color="red",zorder=1,alpha=0.3)
ax.set_title(u"zorder對比,和html中的z-index類似")

ax = plt.subplot(339)
ax.axis([-2,2,-2,2])
font = {'family': 'serif',
        'color':  'darkred',
        'weight': 'normal',
        'size': 16,
        }
ax.text(0,0,'TEXT',size=15,fontdict=font)
ax.set_title("fontdict")

plt.gcf().set_size_inches(12,10)
plt.savefig("text.png")
plt.show()

大概的樣子就像是下面的樣子的：
