copy created pie chart and calculated values to csv file

I almost completed my project but need some help. Let me summarize what I have already done. I exported a CSV file from ESXI, and using Python, I make several calculations and created a pie chart of these values. Here I have one result for calculation and the pie chart. Currently, I want to write these results to CSV simultaneously. How can I do that? As you know, pandas only display pie charts on different windows. I want to save that chart on CSV.

A pie chart is just a type of data visualization. I guess you are already using a dataframe to display this using plt.show().if you want to save that chart,
you could combine data,labels,colors to dataframe and save it as a csv. In order to save as csv: df.to_csv(file_name, sep='\t')

How to set color for last row in excel using pandas python

I am using pandas to read data from csv file and write into excel . I have done that one. I want to set bgcolor for last row in excel using pandas. Can anyone plz give some ideas to set color for last row.

I'm not sure if Pandas has capability to do this. However, once you save your file using Pandas, you can reload it and later change the last row color using xlsxwriter.
Refer here for how to use xlsxwriter.

Custom data labels for charts with XlsxWriter

I'm trying to create a some of a complex chart using XlsxWriter, thus I need to add some data labels to my series. The problem is that the data labels I need are different from the series value.
Within Excel is something simple to do:
1) right click format data labels
2) label contains: values from cells
3) I then select the cells I want and it creates the data labels
If there is any way to do this, thanks in advance.

This feature isn't supported since it wasn't part of the original Excel 2007 file format.
There is a feature request for this: XlsxWriter/feature_request/343.

How to plot on box plot 2 data from different data frama - Python

I'm facing a problem to plot 2 box plots into a same graph to make easier to compare them.
The problems is that each box plot comes from a different dataframe with different lenght, however, both have same columns.
My two data frame are:
'headlamp_water' and 'headlamp_crack'; the column I want to use is called 'Use Period'.
How do I do it?
Any help will be highly appreciated

You can concat() the columns and call the boxplot() method.
pd.concat([headlamp_water['Use Period'], headlamp_crack['Use Period']], axis=1).boxplot()
Using axis=1, you select the columns.
