Python 条形图在数组中绘制负x值，尽管数组中没有负值

我得到了这个错误，当绘制两个数组时，我有负的x值，尽管我的x轴数组中没有任何负值。我的x轴应在最小值0.005到最大值0.995之间。不应在此范围之外定义任何值。我不知道为什么会这样

print(xValsAppx)
print()
print(probabilityX)

plt.bar(xValsAppx, probabilityX)
plt.xlabel('Sample')
plt.ylabel('Probability of Observing the Sample')
plt.title('Normal Distribution for a = 0, b = 1')

其中xValsAppx是

[0.005 0.015 0.025 0.035 0.045 0.055 0.065 0.075 0.085 0.095 0.105 0.115

图片如下：

查看，条形图的默认宽度为0.8，这不适合您的x值。尝试例如0.008或0.01
