这是更多关于3D直方图创建Python中的一般问题。

This is more of a general question about 3d histogram creation in python.

我试图用X和Y阵列以下code创建一个3D柱状图

I have attempted to create a 3d histogram using the X and Y arrays in the following code

import matplotlib
import pylab
import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d.axes3d import Axes3D
from matplotlib import cm

def threedhist():
    X = [1, 3, 5, 8, 6, 7, 1, 2, 4, 5]
    Y = [3, 4, 3, 6, 5, 3, 1, 2, 3, 8]
    fig = pylab.figure()
    ax = Axes3D(fig)
    ax.hist([X, Y], bins=10, range=[[0, 10], [0, 10]])
    plt.xlabel('X')
    plt.ylabel('Y')
    plt.zlabel('Frequency')
    plt.title('Histogram')
    plt.show()

不过，我收到以下错误

However, I am getting the following error

我在该行尝试了code有和没有[ ax.hist（[X，Y]，箱柜= 10，范围= [[0，10]，[0，10]]） 我也试过功能从numpy的无功而返 H，xedges，yedges = np.histogram2d（X，Y，箱柜=（10，10）） 我缺少的一个步骤或参数？任何意见将大大AP preciated。

I have tried the code with and without the "[" in the line ax.hist([X, Y], bins=10, range=[[0, 10], [0, 10]]) I have also tried the function from numpy without success H, xedges, yedges = np.histogram2d(x, y, bins = (10, 10)) Am I missing a step or a parameter? Any advice would be greatly appreciated.

推荐答案

在此应答有二维的解决方案散点和3D直方图。用法很简单：

In this answer there is a solution for 2D and 3D Histograms of scattered points. The usage is simple:

points, sub = hist2d_scatter( radius, density, bins=4 )

points, sub = hist3d_scatter( temperature, density, radius, bins=4 )

其中，子是 matplotlib 插曲实例（3D与否）和分包含用于散点图的点。

Where sub is a matplotlib "Subplot" instance (3D or not) and pointscontains the points used for the scatter plot.
