我pandas DataFrame使用matplotlib(from this answer)绘制了一个表格。
现在我想设置给定行的底部边缘颜色,我有这个代码:
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
import matplotlib
import six
df = pd.DataFrame()
df['date'] = ['2016-04-01', '2016-04-02', '2016-04-03', '2016-04-04']
df['calories'] = [2200, 2100, 1500, 1800]
df['sleep hours'] = [2200, 2100, 1500, 1500]
df['gym'] = [True, False, False, True]
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) ])
return ax
def get_table(ax):
table = None
for child in ax.get_children():
if isinstance(child, matplotlib.table.Table):
table = child
return table
return table
def set_row_edge_color(ax, row, color):
table = get_table(ax)
for k, cell in six.iteritems(table._cells):
if (k[0] == row):
cell.set_edgecolor(color)
ax = render_mpl_table(df, header_columns=0, col_width=2.0)
set_row_edge_color(ax, 2, 'k')
plt.show()
我无法只设置行底部的颜色,它设置如下:
有没有办法像这样只设置行底颜色?
或者有没有办法在图形/图中定位行并绘制一条水平线?
莫回无
