I use python 3.4, pandas 0.14.1 and XlsxWriter 0.5.6.
I create a graph called 'graph' using pandas with the following code
graph=data_iter['_DiffPrice'].hist()
, which produces a beautiful histogram.
Now, how do I insert that graph into an Excel file using XlsxWriter?
I tried the XlsxWriter method
workbook.add_chart()
but this creates a graph in Excel, not what I want.
Thanks
If you would like to export Pandas data as charts in Excel using XlsxWriter then have a look at the following how-to (that I wrote): Using Pandas and XlsxWriter to create Excel charts.
If on the other hand you want the matplotlib style charts generated by Pandas then export them as images and insert them into a worksheet using the XlsxWriter insert_image() method.

So I have an excel file (.xlsx) on a Linux machine, and that excel file contains cells with formulas. What I would like to do is edit an input cell's value (i.e. not a formula cell, just a regular cell that contains a simple string) and then read the resulting calculated formula values using Python.
I have code that works well on Windows:
I can use openpyxl version 3.0.1 to do the initial edit of the excel file, and then save/close. (I use an older version of openpyxl (3.0.1) to avoid corruption of the excel file that happens in openpyxl 3.1.1).
Since openpyxl doesn't calculate formula values (it leaves that heavy lifting to excel itself), I use xlwings to have the actual excel application simply open the file and then save/close it to generate the cached formula values that openpyxl can read.
I can then again use openpyxl to read the cached formula calculated values of the updated excel file to get what I want.
So that all works well on Windows, but on Linux, I'm struggling to find a way to edit an excel file and then read the resulting calculated results of cells with formulas after the edit of the excel file (can't use xlwings since it's Windows only since it uses win32com). Is what I want possible with Pandas (I thought Pandas uses openpyxl under the hood)?
Thanks!
I am trying to create histograms in multiple sheets of an excel workbook. I can very easily crate chart using pandas or matplotlib libraries and show it in python output window. However I would like to plot the histogram chart in excel. I am using office 360. Is there a way to do so?
You can create a histogram chart with XlsxWriter using an Excel "Column" chart type: Column chart example
See also the Working with Charts section of the XlsxWriter docs.
I have a Pandas dataframe/crosstab that I am able to export to an .xlsx document, but it's plainly formatted. I've messed around and created Seaborn Heatmap visualizations with the dataframe, but would love to have the Seaborn Heatmap formatting within the excel spreadsheet. Is this possible?
Thank you very much.
I was successfully able to generate Stacked Column charts in the newly created Excel sheet using pandas dataframe with xlsxwriter of Python Pandas. But, I can't figure out how to assign color yet.
Here is the picture.
This is from Pandas xlsxwriter documentation. In the given picture, each "Metric" has different colors. For Example, Metric 8 is pink and Metric 1 is blue. I want to assign specific colors to each metric in this example. Obviously, each metric belongs to each row of data in question.
I understand I can do this in excel individually. But, I am writing Python code to generate several dozens of stacked column charts and put it in excel using xlsxwriter. So, it is not practical to do this by hand.
Any help is appreciated !
You need to set the fill color for the series.
See the following Pandas-XlsxWriter stacked charts with colors example. The example uses brew colors but you can replace those with any Html like RGB color.
See also the XlsxWriter Chart documentation and Working with Charts which explain the API and give examples of setting the colors of different properties.
I am very beginner in python and i am learning ipython notebook. I am able to read excel file but i did not able to draw graphs from excel file.!

Can you give me reference or code where i can learn python panda graphs.
You could also consider using pandas to read the sheets, and matplotlib to display graphs. http://matplotlib.org/gallery.html
