#创建一个D6

#掷几次骰子，并将结果存储在一个列表中

#分析结果
frequencies=[]
for value in range(1,die.num_sides+1):
frequency=results.count(value)
frequencies.append(frequency)

#print(frequencies)

#对结果可视化
hist=pygal.Bar()
hist.title='Results of rolling one D6 1000 times'
hist.x_labels=['1','2','3','4','5','6']
hist.X_title='Result'
hist.y_title='Frequency of Result'

hist.add('D6',frequencies)
hist.render_to_file('die_visual.svg')

这是程序，有y_title，为什么没有x_title
