二、测试：

1、函数draw_pie(surface, options, dataSet)：

 

2、函数draw_vertical_bar(surface, options, dataSet)：

3、函数draw_horizontal_bar(surface, options, dataSet)：

4、函数draw_line(surface, options, dataSet):

5、函数draw_scatterplot(surface, options, dataSet)：

6、函数draw_stackedverticalbarChar(surface, options, dataSet)：

7、函数draw_stackedhorizontalbarChart(surface, options, dataSet)：
