python数据可视化——柱状图1

先看效果：

Caption

代码如下：

# -*- coding: utf-8 -*-
import matplotlib.pyplot as plt

def draw_bar(same_score, diff_score):
    plt.title("same/different pairs seq score histogram")
    plt.hist(same_score, bins=10, facecolor="red", edgecolor="black", label='same', alpha=0.7)
    plt.hist(diff_score, bins=10, facecolor="blue", edgecolor="black",label='different', alpha=0.7)
    plt.xlabel("score")
    plt.ylabel("number")
    plt.legend()
    plt.savefig("test.png")
    plt.show()


if __name__ == "__main__":
    # 自己乱造的数据 
    same_score = [0.81, 0.92, 0.88, 0.99, 0.77, 0.90, 0.999, 0.76]
    diff_score = [0.22, 0.44, 0.68, 0.66, 0.76, 0.88, 0.66, 0.65, 0.77]
    draw_bar(same_score, diff_score)

此代码可以统计数据的分布。
