是否可以在JointGrid的直方图中添加百分比?
我可以以低于,高于或高于酒吧的百分比生活。 或用额外的轴显示百分比+线。 我遍历了JointGrid的源代码,找到了一种方法来获取两个直方图的隐藏轴,以便为它们添加百分比。
我还为直方图轴尝试了不同的标签,但是由于它们是共享的,因此不起作用:
hex.ax_marg_y.set_yticklabels(["test", "label"])
这是我正在进行的工作:
labels = ['Ma 13', 'Di 14', 'Wo 15', 'Do 16', 'Vr 17', 'Za 18', 'Zo 19', 'Ma 20']
hex = sns.JointGrid(x, y, height = 12)
hex.ax_marg_x.hist(x, bins=np.arange(-0.5, 23.5))
hex.ax_marg_y.hist(y, bins=np.arange(-0.5, len(labels) + 0.5), orientation="horizontal")
hex.plot_joint(sns.kdeplot, shade=True, cmap="Blues", bw=.11)
plt.ylim(-0.5, len(labels)-0.5)
plt.xlim(-0.5, 23.5)
hex.ax_joint.set_xticks(range(24))
hex.ax_joint.set_yticks(range(len(labels)))
hex.ax_joint.set_yticklabels(labels)
plt.subplots_adjust(left=0.05, right=0.95, top=0.93, bottom=0) # Shrink figure so the legende is visible
hex.x = x2
hex.y = y2
hex.plot_joint(plt.scatter, marker = 'x', c = 'r', s = 190)
plt.show()
答案 0 :(得分:0)
如果您要保存对ax_marg_{x|y}.hist()
返回的艺术家的引用,则只需遍历每个人并在正确的位置进行注释即可。
tips = sns.load_dataset("tips")
x = tips['total_bill']
y = tips['tip']
hex = sns.JointGrid(x, y)
_,_,bars_x = hex.ax_marg_x.hist(x)
_,_,bars_y = hex.ax_marg_y.hist(y, orientation="horizontal")
hex.plot_joint(sns.kdeplot, shade=True, cmap="Blues")
# annotate top hist
total_height = np.sum([bar.get_height() for bar in bars_x])
for bar in bars_x:
height = bar.get_height()
hex.ax_marg_x.annotate('{:.1f}%'.format(100*height/total_height),
xy=(bar.get_x() + bar.get_width() / 2, height),
