所以我有一个数据集,我试图将其合并到一个矩阵中,然后制作一个线框图。当我显示绘图时,所有显示的是沿着3d图像的x = y线的平面。我想要完整的矩阵显示。我已经包含了我的代码以及stats.txt的示例:
from numpy import *
from pylab import *
f = open('stats.txt')
bins = 10
xs = []
ys = []
for line in f:
line = line.strip().split(' ')
xs.append(float(line[0]))
ys.append(float(line[1]))
xlin = linspace(min(xs),max(xs),bins+1)
ylin = linspace(min(ys),max(ys),bins+1)
matrix = zeros((bins,bins))
for i in range(bins):
for j in range(bins):
count = 0
for s in range(len(xs)):
if xs[s] >= xlin[i] and xs[s] <= xlin[i+1] and ys[s] >= ylin[j] and ys[s] <= ylin[j+1]:
count +=1
matrix[i,j] = count
print matrix
x = []
y = []
for i in range(bins):
x.append([0.,1.,2.,3.,4.,5.,6.,7.,8.,9.])
for i in range(bins):
y.append([0.,1.,2.,3.,4.,5.,6.,7.,8.,9.])
#for i in range(bins):
# y.append(linspace(0,bins-1,bins))
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d.axes3d import Axes3D
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
print shape(x)
print shape(y)
print shape(matrix)
ax.plot_wireframe(x, y, matrix)
#plt.imshow(matrix,cmap=plt.cm.ocean)
plt.show()
stats.txt示例:

您的代码存在的问题是您的x坐标与每个数据点的y坐标相同。因此,您有效地告诉matplotlib您在x-y平面的对角线上只有值。
一种可能的解决方案是简单地转置你的y坐标。但是,使用numpy的meshgrid
(link)函数可能会更舒服。
x,y = np.meshgrid(np.arange(bins),np.arange(bins))
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
ax.plot_wireframe(x, y, matrix)
