Bug in python visual

htp84 · ‎08-12-2018

I cannot plot data using python. Seems like a localisation problem, comma is used instead of full stop as a decimal separator in a matplotlib function.

Thanks for posting this! I have the same problem in two different notebooks. I live in Hungary.

You can set the figsize in the code and it will give you a different error. Personally, I try to not waste time with experimenting and wait for a solution posted here.

I was testing around this matplot lib code and found this error

@htp84 @Kumail,

Could you please share sample data of your table and detailed Python script so that I can test?

Regards,
Lydia

Kumail · ‎08-14-2018

Hi @v-yuezhe-msft

These are the sample codes I was running.

1-

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
df = pd.DataFrame(np.random.randn(1000, 4), index=ts.index, columns=list('ABCD'))
df = df.cumsum()
plt.figure(); df.plot();

2-

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
df1= pd.DataFrame({'employee': ['Bob', 'Jake', 'Lisa', 'Sue'],
'ages': [10, 40, 58, 25], 'salary': [1000, 40000, 58000, 25000]})
plt.figure(); df1.plot.bar();

htp84 · ‎08-14-2018

@v-yuezhe-msft

I cannot share my original data but I have (almost) succeded to reproduce the error using the train dataset of this kaggle competition: https://www.kaggle.com/c/house-prices-advanced-regression-techniques

I get a similar error as my original post. Below is the code I used and the error message:

import pandas as pd
import matplotlib.pyplot as plt
dataset.YrSold = dataset.YrSold.astype(str)
dfPerYear = dataset.groupby(by="YrSold").sum().reset_index()
dfPerYear.plot(x="YrSold", y="SalePrice", kind="line")
plt.show()

Hi,

A temporary solution to the problem is in the “Region and Language”. If you have a comma as separator, PowierBI building a script PythonScriptWrapper.PY and takes this setting to enter floating numbers to it and that is wrong. By default, I use Polish regional settings and I faced the same problem. After changing "Decimal symbol" to the dot, I was able to plot data with a Python script. Keep in mind that you have to change the decimal symbol's setting in "Customize Format" before launching PowerBI.

Solution

Regards,

Tom

There is a well-described issue about this on Stackoverflow which has a link to this page.

@tomyc Thank you, it works

@HadiRajani You have to add plt.show() in the bottom of your script. Also, the import of numpy and the use of plt.figure() is unnecassary in the example.

Below is a modified version of your code that works on my computer after I changed my regional setting using @tomyc temporary solution.

import matplotlib.pyplot as plt
df1 = pd.DataFrame({'employee': ['Bob', 'Jake', 'Lisa', 'Sue'],
