问题描述
最近 matplotlib 添加了对 小提琴图 的原生支持.我想要做的是 half-violin plot as 此处.我想可以通过更改函数返回的 body 来完成.您是否知道如何像示例中那样绘制半小提琴图,但是使用matplotlib中的新功能?
Recently matplotlib has added a native support for violin plot. What I want to do is half-violin plot as here. I guess that it can be done changing the body the function is returning. Do you know how to plot half violin plot as in the example but using the new function from matplotlib?
推荐答案 data1 = (np.random.normal(0, 1, size=10000), np.random.normal(0, 2, size=10000)) data2 = (np.random.normal(1, 1, size=10000), np.random.normal(1, 2, size=10000)) fig, ax = plt.subplots(figsize=(18, 7)) v1 = ax.violinplot(data1, points=100, positions=np.arange(0, len(data1)), showmeans=False, showextrema=False, showmedians=False) for b in v1['bodies']: # get the center m = np.mean(b.get_paths()[0].vertices[:, 0]) # modify the paths to not go further right than the center b.get_paths()[0].vertices[:, 0] = np.clip(b.get_paths()[0].vertices[:, 0], -np.inf, m) b.set_color('r') v2 = ax.violinplot(data2, points=100, positions=np.arange(0, len(data2)), showmeans=False, showextrema=False, showmedians=False) for b in v2['bodies']: # get the center m = np.mean(b.get_paths()[0].vertices[:, 0]) # modify the paths to not go further left than the center b.get_paths()[0].vertices[:, 0] = np.clip(b.get_paths()[0].vertices[:, 0], m, np.inf) b.set_color('b') ax.legend([v1['bodies'][0],v2['bodies'][0]],['data1', 'data2'])
