view部分代码
def show(request):
exceptions = Exception.objects.order_by("-hit")[:5]
# exceptions = Exception.objects.all()
listx = []
listy = []
for exception in exceptions: #遍历，拼横纵坐标
listx.append(int(exception.hit))
listy.append(str(exception.name))

return render(request, "show.html", {'exceptions': exceptions, 'X': listx, 'Y': listy})

页面显示

backgroundColor: ((Highcharts.theme && Highcharts.theme.legendBackgroundColor) || '#FFFFFF'),
背景是黑色了吧，置为'#FFFFFF'试试
