问题描述
尝试在 Power BI 中插入 Python 可视化时，我不断收到错误 TypeError: from_bounds() 需要 4 个位置参数，但给出了 6 个.虽然看起来 Matplotlib 是这里的问题，但我不知道这是否是根本原因.
我的系统:
Windows 7, 64 位Power BI 2018 年 8 月Python 3.6.6.0Matplotlib 2.2.2熊猫 0.23.4我不能 100% 确定这实际上是一个版本问题，但我想不出其他任何事情，因为我使用的是在帖子中成功使用的相同数据集

好的，现在很明显错误来自哪里.
在行中(Power BI 即时生成):
matplotlib.pyplot.figure(figsize=(5,87473572938689,6,87403100775194))它获取您的语言环境中的尺寸(在这种情况下使用，"作为小数点)并将其传递给 figsize.
而 figsize 接受 (width, height) 的元组以英寸为单位作为输入，5,87473572938689,6,87403100775194 被视为 4 个参数，而不是 2 个，这会导致错误.
所以要解决这个问题，您可以将 figsize(使用带有 . 作为小数点的值)显式传递给 plt.figure，即:
import matplotlib.pyplot as pltplt.figure(figsize=(5.874,6.874))plt.plot(数据集['日期']，数据集['值'])plt.show()或者将 Power BI 中的区域设置更改为使用 . 作为小数点而不是 ,.
I keep getting the error TypeError: from_bounds() takes 4 positional arguments but 6 were given when trying to insert a Python Visualization in Power BI.
Though it seems that Matplotlib is the problem here, I don't know if that is the root cause.
My system:

Python 3.6.6.0
Matplotlib 2.2.2
Pandas 0.23.4
I can't be 100% sure that this is in fact a version problem, but I can't think of anything else because I'm using the same dataset that was successfully used in the post What is the best data format for a time series in a Python Visualization in Power BI?.

OK now it's obvious where the error comes from.
In the line (which Power BI generates on the fly):
matplotlib.pyplot.figure(figsize=(5,87473572938689,6,87403100775194))
It grabs the dimensions in your locale (which in this case use ',' as decimal point) and passes it to figsize.
While figsize accepts a tuple of (width, height) in inches as input, 5,87473572938689,6,87403100775194 is treated as 4 arguments, instead of 2, which causes the error.
So to work around this, you can either explicitly pass figsize (using values with . as decimal point) to plt.figure, i.e.:
import matplotlib.pyplot as plt
plt.figure(figsize=(5.874,6.874))
plt.plot(dataset['Date'], dataset['Value'])
plt.show()
Or change the locale in Power BI to one which use . as decimal points instead of ,.
