目标是使用 Matplotlib 从 df 创建一个表。然后,我希望标题(日期、卡路里、 sleep 时间)旋转 90 度。
最初,我认为这可以通过访问每个标签并使用label.set_rotation(90)
旋转它来实现。然而,它并没有如预期的那样实现。
我可以知道如何解决这个问题吗?
完整代码如下
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
import six
df = pd.DataFrame ()
df ['date'] = ['2016-04-01', '2016-04-02', '2016-04-03']
df ['calories'] = [2200, 2100, 1500]
df ['sleep hours'] = [2200, 2100, 1500]
df ['gym'] = [True, False, False]
def render_mpl_table(data, col_width=3.0, row_height=0.625, font_size=14,
header_color='#40466e', row_colors=['#f1f1f2', 'w'], edge_color='w',
bbox=[0, 0, 1, 1], header_columns=0,
ax=None, **kwargs):
if ax is None:
size = (np.array(data.shape[::-1]) + np.array([0, 1])) * np.array([col_width, row_height])
fig, ax = plt.subplots(figsize=size)
ax.axis('off')
mpl_table = ax.table(cellText=data.values, bbox=bbox, colLabels=data.columns, **kwargs)
mpl_table.auto_set_font_size(False)
mpl_table.set_fontsize(font_size)
for k, cell in six.iteritems(mpl_table._cells):
cell.set_edgecolor(edge_color)
if k[0] == 0 or k[1] < header_columns:
cell.set_text_props(weight='bold', color='w')
cell.set_facecolor(header_color)
else:
cell.set_facecolor(row_colors[k[0]%len(row_colors) ])
for label in ax.get_xticklabels():
# https://stackoverflow.com/a/43153984/6446053
label.set_ha("right")
label.set_rotation(90)
return ax
render_mpl_table (df, header_columns=0, col_width=2.0)
plt.show ()
提前致谢。
最佳答案
您可以在标题行中设置文本属性rotation
,如下所示:
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
import six
df = pd.DataFrame ()
df ['date'] = ['2016-04-01', '2016-04-02', '2016-04-03']
df ['calories'] = [2200, 2100, 1500]
df ['sleep hours'] = [2200, 2100, 1500]
df ['gym'] = [True, False, False]
def render_mpl_table(data, col_width=3.0, row_height=0.625, font_size=14,
header_color='#40466e', row_colors=['#f1f1f2', 'w'], edge_color='w',
bbox=[0, 0, 1, 1], header_columns=0, header_height=2.0,
ax=None, **kwargs):
if ax is None:
size = (np.array(data.shape[::-1]) + np.array([0, 1])) * np.array([col_width, row_height])
size[1] += header_height - row_height
fig, ax = plt.subplots(figsize=size)
ax.axis('off')
mpl_table = ax.table(cellText=data.values, bbox=bbox, colLabels=data.columns, **kwargs)
mpl_table.auto_set_font_size(False)
mpl_table.set_fontsize(font_size)
for k, cell in six.iteritems(mpl_table._cells):
cell.set_edgecolor(edge_color)
if k[0] == 0 or k[1] < header_columns:
cell.set_text_props(weight='bold', color='w')
cell.set_facecolor(header_color)
cell.set_text_props(rotation='vertical')
cell.set_height(header_height)
else:
cell.set_facecolor(row_colors[k[0]%len(row_colors) ])
cell.set_height(row_height)
return ax
render_mpl_table (df, header_columns=0, col_width=2.0, header_height=2.0)
plt.show ()
请注意,我在示例中手动调整了行高。
