chart.js cn看不到数据的形状

Question

它在本地主机上工作，但是在我发布应用程序之后，我发现了结果 这是我尝试使用的代码

import matplotlib.pyplot as plt
import numpy as np
from scipy.ndimage.filters import gaussian_filter1d

def gaussian( x , s):
    return 1./np.sqrt( 2. * np.pi * s**2 ) * np.exp( -x**2 / ( 2. * s**2 ) )

myData = np.zeros(25)
myData[ 12 ] = 1
myGaussian = np.fromiter( (gaussian( x , 1 ) for x in range( -3, 4, 1 ) ), np.float )
filterdData = gaussian_filter1d( myData, 1 )

myFilteredData = np.convolve( myData, myGaussian, mode='same' )
fig = plt.figure(1)

ax = fig.add_subplot( 2, 1, 1 )
ax.plot( myData, marker='x', label='peak' )
ax.plot( filterdData, marker='^',label='filter1D smeared peak' )
ax.plot( myGaussian, marker='v',label='test Gaussian' )
ax.plot( myFilteredData, marker='v', linestyle=':' ,label='convolve smeared peak' )
ax.legend( bbox_to_anchor=( 1.05, 1 ), loc=2 )
