# 七彩散点图 Colorful scatterplot
def scatterplot_colorful():
    # 输入横坐标x序列
    x=np.array([x for x in range(1,21)])
    # 输入y序列,或者y与x的关系
    y=x**2
    # 定义颜色的列表
    colors=['red','green','gray','purple','yellow','orange','blue']
    # 随机排列颜色
    random_colors=random.sample(colors,7)
    # print(random_colors)
    # 生成一个画布
    fig=plt.figure()
    # 散点图绘制
    plt.scatter(x,y,s=100,c=random_colors,alpha=0.8)
    plt.xticks(x)
    # 显示获得图片
    fig.show()
    # 或者
    # plt.show()

# 如果当前模块作为主模块运行
if __name__ == '__main__':
    # 实例化七彩散点图
    sca=scatterplot_colorful()
