通过对柱形图分析发现，歌单对歌曲的收录情况多数集中在20-60首歌曲，至多超过80首，也存在空歌单现象，但绝大多数歌单收录歌曲均超过10首左右。这次可视化分析将有助于后续创作者更好地收录歌曲到自己的创作歌单中。也能够更受大众欢迎。

可以通过此标签图看出歌单的风格，可以分析出目前的主流歌曲的情感，以及大众的需求，也网易云音乐用户的音乐偏好，据此可以看出，网易云音乐用户，在音乐偏好上比较多元化：国内流行、欧美流行、电子、 等各种风格均有涉及。

get_matplot(x,y,chart,title,ha,size,color)
x表示充当x轴数据；
y表示充当y轴数据；
chart表示图标类型，这里分为三种barh、hist、squarify.plot；
ha表示文本相对朝向；
