Quick Graphing via Excel [ID:621] (4/6)

in series: COM and Python with pyWin32

(Showmedo is undergoing major changes. To report any problems viewing the videos please email us and include browser and OS specifics. Cheers - Kyran.)

Would you like to output some numbers in Python and see them graphed in Excel? This is really easy to do if we have an Excel XLS sheet already setup with a graph object.

NOTE - I mention SaveAs, I show this in the next episode

# get a new app
from win32com.client import Dispatch
xlApp = Dispatch("Excel.Application")

# show excel
xlApp.Visible=1

# create an XLS file
# using sheet1, select a1-a4, select Chart|Area, Next, Next, Finish

# load a pre-created excel sheet
sheet_file_name = r"C:\pyWin32_tutorial\chart1.xls"
xlBook = xlApp.Workbooks.Open(sheet_file_name)

xlSheet = xlBook.Sheets(1)
xlSheet.Name = "My Chart"
xlSheet.Cells(1,1).Value="My Chart"
xlSheet.Cells(2,1).Value="2"
xlSheet.Cells(3,1).Value="8"
xlSheet.Cells(4,1).Value="32"

# print some or all of the book
#xlBook.PrintOut()
#xlSheet.PrintOut()

# close this workbook without saving it
#xlBook.Close(SaveChanges=0)
#xlApp.Quit()
#del xlApp

These are wonderful videos. Thank you.


I have started to use excel as the output of data computed via python. I really appreciated these lessons as they are easy to follow. Please make more of them if possible.

Interested in knowing how to simulate the fancy stuff that excel files allow users to do...like executing stuff from exel's menus (sort, insert picture...).

Thank you again.


Hi Shadowdog. In theory you can create the chart in code, you'll need to learn more about Microsoft's API to do that. I imagine that the API code is available on line, it is free with MS VC++ (at least - it was when I last wrote C++ a few years back).

Ian.


Review of Quick Graphing via Excel

Educating the Open-source Community With Showmedo

Although as important as the software it supports, education and documentation are relatively neglected in the Open-source world. Coders love to code, and explaining how best to use or improve the software tends to be deferred or even sidelined.

At Showmedo we believe the community can play a vital role here and also say thanks for the tools and software that make our lives easier. If you have a piece of software you love or a programming langugage you are enthusiastic about, why not make a screencast showing others how to use it? All the stuff you wish you'd been told, the tips, tricks, insights that would have saved you time and frustration.

Screencasting is easier than you think, and we're happy to help you. You can emailus for advice or just use some of the how-to screencasts on the site. This screencasting learning-pathis a good place to start.

Kudos and Thanks for Ian
