当绘制matplot图像时，Python突然停止了。 我想在index.html中显示matplot图像的表。现在我在views.py
中写道def past_result(request):
return render(request, 'index.html', {'chart': _view_plot(request)})
def _view_plot(request):
dates = [20150805,20160902,20170823]
heights = [5,6,3]
df = pd.DataFrame()
df['DATE'] = dates
df['SCORE'] = heights
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
if ax is None:
size = (np.array(df.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=df.values, bbox=bbox, colLabels=df.columns)
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)])
plt.show()
return ax
<img src="data:image/png;base64,{{ chart }}" width="700px" height="500px" alt="RESULT"/>
当我阅读past_result方法时，Python突然停止了。我不知道为什么。为什么会发生这样的错误？我读这个网址作为参考 How to save the Pandas dataframe/series data as a figure?。我该如何解决这个问题？
