我如何获得 seaborn distplot 中分布峰值 y 值的 X 轴值？

Question

So i have a frequency distribution plot that looks like this:

image of the Desired point

an i need the x value corresponding to the peak of the y value. How can i get it for the plotting code?

seaborn.distplot('TheSeries',bins = 30, ax=axes[0][1])

Can someone explain how i can get that corresponding value for this and similar cases?

Answer 1

You can extract the coordinates of the kde curve from ax.lines[-1] and use np.argmax() to find the mode of the curve.

Note the in the latest seaborn version distplot has been deprecated. Here histplot with kde=True would be its replacement.

from matplotlib import pyplot as plt
import numpy as np
import seaborn as sns

samples = np.random.randn(300) ** 2 * 50
ax = sns.histplot(samples, bins=30, kde=True, color='skyblue')
kdeline = ax.lines[0]
xs = kdeline.get_xdata()
ys = kdeline.get_ydata()
mode_idx = np.argmax(ys)
ax.vlines(xs[mode_idx], 0, ys[mode_idx], color='tomato', ls='--', lw=2)
plt.show()
