Bar chart or Line? Scatter plot or box plot? These are the questions we ask ourselves when we set out to make a chart. In this article let me tell you how to pick a chart type so you can make best charts for every situation.
Why is it important to pick right chart?
Because right charts lead to right decisions. We use charts to tell stories, evaluate alternatives, understand trends or find-out if everything is normal. So, an incorrect charting choice can lead to poor judgment of the messages where as a correct chart can lead to right and faster decisions.
How to pick a chart type:
Chart making process can be divided in to 4 steps
- Find-out what you want to say?
- (Re)arrange the data
- Prepare the chart
- Format the chart
1. What is the purpose of this chart?
This is the first and most important step in chart preparation. You must ask yourself, “what is the purpose of this chart?”. Once we know the clear reason why the chart should exist, we will naturally be able to select the correct chart type for that reason.
But I realize that finding the reason itself can be a bit tedious. So I have listed down 6 common reasons that we often have to make a chart:
- to Compare
- to show the Distribution
- to explain Parts of the Whole
- to tell the Trend over time
- to findout the Deviations
- to understand the Relationship
Let us understand these reasons along with the type of charts that go well with these.
1. To Compare:
What it means? You want to compare one set of value(s) with another.
Examples:
- Performance of Product A vs. Product B in 5 regions
- Interview performance of various candidates
Charts that can be used for this reason:
- Bar Charts,
- Column Charts
- Scatter Plots
- Pie Charts
- Line Charts
- Data Tables
2. To Show the Distribution
What it means? You want to show the distribution of a set of values (to understand the outliers, normal ranges etc.)
Examples:
- Distribution of Call waiting times in a call center
- Distribution of bugs found in 10 week software testing phase
Charts that can be used to show distribution:
- Column Charts
- Scatter Plots
- Line charts
- Box Plots
3. Parts of Whole
What it means? You want to show how various parts comprise the whole
Examples:
- Individual product sales as a percentage of whole revenue
- Browser types of customers visiting our website
Charts that can be used to show Parts of Whole:
- Column Charts
- Bar Charts
- Pie Charts
- Data Table
4. Trend over time
What it means? You want to understand the trend over time of some variable(s).
Examples:
- Customer footfalls on the last 365 days
- Share price of MSFT in the last 100 trading sessions
Charts that can be used to show Trend Over Time:
- Column Charts
- Line Charts
- Data Table
5. Deviations
What it means? You want to see which values deviate from the norm.
Examples:
- Failures (or bugs) in the context of Quality Control
- Sales in Various Stores
Charts that can be used to show Deviations:
- Column Charts
- Bar Charts
- Line Charts
- Data Table
6. Relationship
What it means? You want to establish (or show) relationship between 2 (or more) variables
Examples:
- Relationship between Search Phrases and Product Purchases in your website
- Relationship between in-store sales and holidays
Charts that can be used to show Relationship:
- Scatter Plot
- Line Chart
- Data Table
How to pick a chart type when you have more than one reason for the chart?
Simple, use common sense. If I were you, I would either cut down the messages to one or make 2 charts (each conveying one message). If that is not possible, I would consider using dynamic charts or combination charts.
2. (Re)arranging the Data
Even when we know the message and corresponding chart, sometimes, our data may not support us. We then have to rearrange the data. Using excel formulas, pivot tables, tables and data cleaning tools we can easily massage the data.
Once we have the data in required format, we proceed to step 3.
3. Prepare the chart
Since you have already picked the chart type in Step 1, this is very straight forward. Most of the regular charts are available in MS Excel as default charts. You can insert them with few clicks.
But for some special chart types, you may have to prepare the chart by helper series, formatting etc.
4. Format the chart
While most formatting is done as per individual taste, there are some ground rules that apply on almost all charts. Here they are,
- No non-zero axis scale on bar charts [reasons and discussions]
- Make subtle grid-lines (or remove them) [how to remove grid lines]
- Add labels to important points [labeling techniques]
- Add descriptive, bold titles
- Position axis, scales at the right places (for eg. y-axis to the right on a large time series chart)
- Use simple, easy colors
A final word:
The ideas in this post are meant to be guide lines, not final words in the world of visualization. While these rules can help you make a good chart, a great chart take so much more. Knowledge of your data, Passion for what you do and Genuine focus on your audience’ needs can make your chart truly outstanding. All the best.

35 Responses to “Skip weekends while autofilling dates in excel”
[...] Original post by Chandoo [...]
Hi,
Is there any way that I will choose which are my "working days"?
means, I want to leave also Friday as a free day and not only Saturday.
Or, maybe someday I will pick Tuesday as a day off.
I need to also peek Wednessday, Thursday and Friday as days off. Also, for Tuesday, I would need to leave it off once every two weeks. Is there a way to easy achieve this, so that I won't actually add to my workload?
Hi Mihai... you can use pattern fill feature to do this. Simply follow steps in below demo.
Hi,
I am using MS Office 2007 and for some reason, it does not show me these options. It just shows me 3 options:
Copy Cell (Not sure about the exact text)
Copy with Formatting
Copy without Formatting
Any idea how to get those options up?
Regards,
Deep
@Deep : I am not so well versed with 2007, but here is how you can do this using menus:
enter first date of the series
select the range you want to fill
go to menu > edit > fill > series
in the dialog, select date as the series type and "weekdays only" option
press ok...
Let me know if this doesnt work...
Now that was FAST!!!
I tried it but unfortunately it didn't work..
Here is the screenshot:
http://img291.imageshack.us/img291/6573/excelsheetyr2.gif
This is what I tried..
I put the date in one row, in another row, added some calculations (as you can see in the image) and drag the content in other rows..
I could not find any Edit menu so i just clicked on the icon as you have shown in the 2nd image..
I hope I did the right thing...
Hmm...
there should be an edit menu as far as I know. Let me check that...
meanwhile... if it works you can use formulas to fill the series.
1. just enter the first date
2. in the 2nd row, enter a formula like =if(weekday(firstdatecell,2)=6,firstdatecell+2, firstdatecell+1)
3. copy the formula over the rest of the range...
@Deep:
you have to use the autofill handle, the small box at the lower right of the active cell. Right click on the autofill handle and drag down to the cells you want to autofill. A menu pops up showing the weekdays only option and others.
@Chandoo - Thanks but it did not work with my calculations. 🙁
@Robert - Yes, it worked this time but I guess, in my case it won't work as I want to add up the days from the column on the left. (As shown in the image)
Basically this is what I want:
1. I want to define project start date
2. There are no. of days assigned for each module
3. I want excel to calculate the date automatically. (By adding up the no. of days and deducting the weekends)
Any kind of help is appriciated.
Reagrds,
Deep
@Deep,
sorry, I misunderstood your question, I thought you would be searching for the autofill-function only (values).
If I got your request corrctly now, you could use the WORKDAY-function, returning the date before or after a specified number of workdays.
In Excel 2003 and earlier the Add-In Analysis Toolpak has to be installed, but since you are using 2007, it should work immediately.
@Deep.. as Robert suggested, Workday is what you should be using. It will calculate future date based number of working days you want to add to input date. Also, you can use this with your own list of holidays.
Thanks Robert, Chandoo.. I will try the things.. 🙂
I tried it and this time it worked.. Thanks to both of you.. you guys made my life much more easier 🙂
[...] You can also customize excel lists so that you can auto-fill, lets say bank holidays in your country or types of beer in your pub. One more auto fill trick. [...]
Hello,
I understand how to turn off the weekend values for a date fill in a regular auto fill. But, what if you are trying to create a custom one, that counts the amount of days in the formula bar, like 2 days, then 5 days, then 1 day etc etc etc, but they must be working days only and they must not include the weekends.
can that be done?
thanks!
hi..

Hi guys,
How about if I just wanna fill up with weekend? The way I am doing now is using the function weekday and use filter to get weekend. Would appreciate if any one comes up with a better idea. Thank you very much.
Regards
Cheng
What happened to being able to indicate the series by adding a few cells and then using the autofill to copy? I can't get this to work - I need 4 rows with the same date skipping weekends.

Hi Kathy, sorry for a late comment. However, here's the solution.
1.) put your 1st desired date in the 1st 4 cells required (e.g. <cell A1:A4> 2/6/2012)
2.) put the following formula as is in the following four cell (i.e. A5:A8)
=IF(WEEKDAY(A1,2)=5,A1+3, A1+1)
=IF(WEEKDAY(A2,2)=5,A2+3, A1+1)
=IF(WEEKDAY(A2,2)=5,A2+3, A1+1)
=IF(WEEKDAY(A2,2)=5,A2+3, A1+1)
Note: "=5" denotes the number of working days in the week
"+3" denotes the number of days on weekends.
"+1" last denotes the number of days after the working date.
3.) Finally, select cells A4:A8 and then drag drown for furthur dates. The formula will skip Saturday & Sunday in the dates.
Let me know, if you want to tweak the formula as per other ways.
Kamlesh: Thanks for the formula. That was what I was looking for. It works the same in Google Docs Spreadsheets. At first I thought it didn't and did some unnecessary tweaking to make it work.
I was confused by the "IF(WEEKDAY(A2,2)" the modifier 2. I took it out and surpise, the formula didn't work right. I changed the 5 to 6 and then it worked. Turns out, (you probably know this) the default week starts with Sunday. Using 2 makes it start with Monday.
Any way, I didn't know about the Weekday function. Thanks for sharing this post.
Hi, Kamlesh, before i was using "workday" instead of "weekday" but it didn't work.
thanks for sharing the right formula.
At this moment I am going to do my breakfast, when having my breakfast
coming yet again to read further news.
Hi,
I'm using excel 2007
I'm trying to calculate a workday
4 nov 2014(a1) to 12 nov 2014(a2)
Normally i'm using Int formula to do this
=int(a2)-int(a1)
But, hey thats including weekend too... 😀
how do you calculate workday with this condition ?
and if there is not only those day, i mean in a month or two
Thanks before
sagari
@Sagari
=NETWORKDAYS.INTL(DATE(2014,11,4),DATE(2014,11,12),1)
=7
You can also include holidays into the formula by having a list of holidays in say A1:A10
Then use
=NETWORKDAYS.INTL(DATE(2014,11,4),DATE(2014,11,12),1,A1:A10)
Thanks for replying
Get #NAME? in return when using NETWORKDAYS.INTL
But get 7 with NETWORKDAYS
why ??
Hi
i had a query while making a template for one of my school daily task.
Most of the work in these template includes copy from webpage and paste in the template.
so the problem here is, whenevr me or my mates try to do ctrl+v
the format of the cell changes automatically.
I suggested them to use ctrl+alt+v (text) to paste
but they are not ok with it. they want me to make template in such a way that it should work with normal ctrl +v
Any ideas guys ?
Our working week is Tuesday to Saturday if I wish to make a sheet solely using those days is there a formula I can use ?

Dear Sir,
I want to make a series of December month which will show all the dates without Fridays.
Is it Possible sir??
Interesting question Salauddin... The built-in options in Excel can't generate dates like this. But you can use simple formulas to make up such a series.
In first cell (say A1) write the starting date (1-Dec-2019 for example). Makesure this date is not a Friday.
In the next cell (A2) write =WORKDAY.INTL(A1,1,16)
Now drag down the A2 cell to fill up dates. Stop when you reach the end of your range of dates.
If your Excel doesn't have WORKDAY.INTL(), then use the below alternative formula.
=A1+1+(WEEKDAY(A1)=5)
Thank you, Thank you very much sir. it worked perfectly & I was expecting something like that.

Thank you! I've been struggling with this for ages and today, thanks to this post, I finally figured that I had to customize my toolbar in order to utilise the "Fill" menu. This will make my monthly reports much, much neater
