我正在尝试找出如何加粗我正在制作的matplotlib表的列和行标签。
我经历了不同的表属性,我可以弄清楚如何设置单个单元格的样式,而不是实际的列或行标签的样式。
此外,我无法找到粗体显示方式。仅是字体大小,实际字体和颜色。
有帮助吗?
import numpy as np
import matplotlib.pyplot as plt
import pandas as pd
fig, axs =plt.subplots(figsize = (10,6))
clust_data = np.random.random((10,3))
collabel=("col 1", "col 2", "col 3")
axs.axis('tight')
axs.axis('off')
df = pd.DataFrame(np.random.randn(10, 4),
columns=['a','b','c','d'],
index = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j'])
table = axs.table(cellText=df.values, colLabels = df.columns, rowLabels = df.index, loc='center')
plt.show()
编辑:
弄清楚了,尽管有点笨拙。您可以在“ celld”属性中找到列/行标签。然后,您可以使用.set_text_props(fontproperties = FontProperties(weight ='bold'))将其设置为粗体。
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.font_manager import FontProperties
import pandas as pd
fig, axs =plt.subplots(figsize = (10,6))
clust_data = np.random.random((10,3))
collabel=("col 1", "col 2", "col 3")
axs.axis('tight')
axs.axis('off')
df = pd.DataFrame(np.random.randn(10, 4),
columns=['a','b','c','d'],
index = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j'])
table = axs.table(cellText=df.values, colLabels = df.columns, rowLabels = df.index, loc='center')
P = []
for key, cell in table.get_celld().items():
row, col = key
P.append(cell)
for x in P[40:]:
x.set_text_props(fontproperties=FontProperties(weight='bold'))
plt.show()
答案 0 :(得分:2)
遵循documentation的更好的方法:
from matplotlib.font_manager import FontProperties
for (row, col), cell in table.get_celld().items():
if (row == 0) or (col == -1):
cell.set_text_props(fontproperties=FontProperties(weight='bold'))
