Below is the data I have in Microsoft Excel 2010

USER_ID    |    Actual_Count    |   Error_Count
1345653         5                     4
534140349       5                     0
682527813       4                     0
687612723       3                     0
704318001       5                     4

So if you look at the above scenario,

  1. For this 1345653 USER_ID Out of 5, it has 4 errors, same with 704318001 USER_ID, out of 5 it has 4 errors. And all other USER_ID's they didn't have any errors as Error_Count is Zero for them.
  2. So I have total of 8 errors out of 22 tries, So an error percentage is about 36.36%.

So my question is- How should I reflect the above two scenario as a graph in Microsoft Excel 2010 so that when people look into those Graph in Excel 2010, they get the clear picture what is happening. Any help will be appreciated with step by step process what need to be done to make the graph.

P.S I have no prior knowledge of working with Excel before.

This question came from our site for professional and enthusiast programmers.

Just calculate these values and show them in a graph. I will make an example for you. –  davidbuzatto Jul 18 '12 at 4:14
1) What idea are you trying to communicate? (e.g. Certain users are the problem, or the error rate across the board is only 36%) 2) This might be a better question for Cross Validated (stats.stackexchange.com). –  tarheel Jul 18 '12 at 4:18
@tarheel, I want to communicate both of the above scenarios. –  rjchar Jul 18 '12 at 4:22
For future reference this is not an appropriate question for Stack Overflow (not programming). It is musch better suited to Super User –  brettdj Jul 18 '12 at 5:19

I created an example for you. In it, I used your data and created some calculations of them. With these calculations, I created two graphs, one of columns (comparing the total count with the error count) and another comparing the percentage of errors with no errors. Take a look.


If you have any doubt relative that what I did, please comment. I'm using the brazilian portuguese version of excel, but I think that the function that I used (SOMA = SUM) will be "translated" to your version.

Try to change the data to see the graphs being updated.

Thanks david, Yes that will work for me. But can you explain me how you did that step by step so that I can also try the same thing in my excel 2010? it will be of great help to me. –  rjchar Jul 18 '12 at 4:32
Of course I can! The columns A, B and C contains your data. In column F, I used the SUM function, that is able to sum intervals. Select the cell "F2" and take a look at the function editor field (just above). It has this: =SUM(B2:B6) that means: perform a calculation (=) using the SUM function, using the interval B2 to (:) B6. The cell G2 is the same, but for the error count. In H2 I just subtracted the value of F2 in G2 (arithmetic operations may be used as in programming languages). I will continue with a new comment. –  davidbuzatto Jul 18 '12 at 4:37
In the cells I2 and J2 I divide, respectively, the error count by the total and the no error count by the total and formatted these cells using the "percentage" format ("%" button at the "Number" section of the "Start Page" tab). I'm translating the names of the componentes of excel, so maybe I'm missing the correct names ok? –  davidbuzatto Jul 18 '12 at 4:41
Thanks for the comment and what about the grpah? –  rjchar Jul 18 '12 at 4:42
For the graphs, first you go to the "Insert" tab, choose the type of the graph (The first one is columns) and the empty graph will be added. Next you need to select the data that you want to use in the graph. I will not explain step by step because I built the graphs testing the values that I selected until I have what I want. It's not difficult, you just need to explore the editor. Try to use the excel help too, it is very explicative. –  davidbuzatto Jul 18 '12 at 4:44
