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

共享时间序列 = 让Source = Csv.Document(File.Contents("C:data imeseries.csv"),[Delimiter=",",列=2，编码=1252，QuoteStyle=QuoteStyle.None])，#"PromoteHeaders" = Table.PromoteHeaders(Source, [PromoteAllScalars=true]),#"Changed Type" = Table.TransformColumnTypes(#"Promoted Headers",{{"Date", type date}, {"Value", Int64.Type}}) in#"改变类型";
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.
<小时>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:
Windows 7, 64 bit Power BI august 2018 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?.
Data:
Date,Value 2017-01-12,1 2017-01-13,4 2017-01-14,2 2017-01-15,4 2017-01-16,2 2017-01-17,2 2017-01-18,2 2017-01-19,5 2017-01-20,5 2017-01-21,5 2017-01-22,5 2017-01-23,6 2017-01-24,3 2017-01-25,6 2017-01-26,6 2017-01-27,5 2017-01-28,8 2017-01-29,4 2017-01-30,2
Code:
import matplotlib.pyplot as plt plt.plot(dataset['Date'], dataset['Value']) plt.show()

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 ,.
