Why Create Project Timeline Chart?
There are 2 key elements in all the successful projects I have been part of.
- They had exceptional individuals who are also exceptional team players
- The communication and collaboration is really good.
While there is little that project management software can do when it comes to first point, the second point can be addressed by using right tools and visualizations. In this installment and the part 5 and 6 of this series, we will learn some excel based visualizations / charts that can help you to communicate about the project status and progress to your team and stake holders.
Project milestones can be shown in a simple time line chart in excel. While the chart doesn’t look complicated, it can provide good amount of information on project progress in a simple and understandable chart.
We will learn to create a project milestone chart like this:
Steps to create a project milestone chart in excel
- In order to create a project milestone chart, we need to have the milestone data. The simplest format for milestone data is Date and the milestone. But since our chart requires the milestone to be displayed at a certain height on the chart, we will add the third column – height.
PS: the height column can be easily calculated using formulas. I leave it to your imagination. - Once you have the data in the above format, we will add 2 more helper columns – named DUMMY and Milestone. The Dummy column is used to create the timeline (where Y axis value is zero). The milestone column is a more cleaned up version of milestones (see how it is showing #NA where the milestone is blank.)
- Now, select the date and dummy columns and insert a line chart.
- To this chart, we will add one more data series – Height column.
- Now select the height data series and change the chart type to a bar chart. Also set the height series to be plotted on secondary axis. Learn more about combining 2 chart types and adding secondary axis in excel.
- We will also set the horizontal / axis labels for the height series as the “milestones”. We need to do this so that when we set the data labels for the height series, we will see the milestone instead of month.
- At this point our chart should look like this:
- Now, we will add data labels to the height series. Set the label type as “category”
- We will also add error bars to the height series (the bar chart). We will configure the error bar in such a way that they are shown 100% on the negative side only.
- After doing this, the chart should look like this:
- Finally we will do some formatting like,
- Removing fill color / line from height series by setting them to None / transparent.
- Changing the error bar color to a dull shade of gray.
- Adding chart title and aligning it.
- Removing vertical axes and gridlines.
- Formatting horizontal axis – changing label orientation, removing tick marks.
After all this is done, our project milestone time line chart should look like this:
- That is all, we now have a cool looking project milestone chart ready. Now go and achieve a milestone.

I am sure you are overwhelmed reading the above tutorial. You are probably thinking if it is easier to work towards the project milestones than creating this chart. Well, don’t worry. You can download the time line chart template and play with it to suit your needs.

What next?
Project timelines are a great way to tell the story of project to strangers and new people joining your project. They are a good addition to project status meetings and reports.
In the next installment of this series, we will learn how to use Excel to manage timesheets and resources.

Some great contributions here.
Gotta love the Friday 13th formula 😀
Great tips from you all! Thanks a lot for sharing! bsamson, particularly you helped me on a terribly annoying task. 🙂
(BTW, Chandoo, it's not exactly "Find if a range is normally distributed" what my suggestion does. It checks if two proportions are statistically different. I probably gave you a bad explanation on twitter, but it'd be probably better if you fix it here... 🙂 )
Great compilation Chandoo
For the "Clean your text before you lookup"
=VLOOKUP(CLEAN(TRIM(E20)),F5:G18,2,0)
I would like to share a method to convert a number-stored-as-text before you lookup:
=VLOOKUP(E20+0,F5:G18,2,0)
@Peder, yeah, I loved that formula
@Aires: Sorry, I misunderstood your formula. Corrected the heading now.
@John.. that is a cool tip.
Hey Chandoo,
That p-value formula is really great for a statistics person like me.
What a p-value essentially is, is the probability that the results obtained from a statistical test aren't valid. So for example, if my p value is .05, there's a 5% probability that my results are wrong.
You can play with this if you install the Data Analysis Toolpak (which will perform some statistical tests for you AND provide the P Value.)
Let's say for example I've got two weeks of data (separated into columns) with the number of hours worked per day. I want to find out if the total number of hours I worked in week two were really all the different than week one.
Week1 Week2
10 11
12 9
9 10
7 8
5 8
Go to Data > Data Analysis > T-Test Assuming Unequal Variances > OK
In the Variable 1 Box, select the range of data for week 1.
In the Variable 2 Box, select the range of data for week 2.
Check "Labels"
In the Alpha box, select a value (in percentage terms) for how tolerant you are of error.
.05 is the general standard; that is to say I am willing to accept a 95% level of confidence that my result is accuarate.
Select a range output.
Excel calculates a number of results: Average (mean) for each week's data, etc.
You'll notice however that there are two P Values; one-tail and two-tail. (one tail tests are for > or .05), the number of hours I worked in week two is statistically equivalent to the number of hours I worked in week one.
So here’s a way you might want to use this. You put up a new entry on your blog. You think it’s the best entry ever! So you pull your webstats for this week and compare it to last week. You gather data for each week on the length of time a visitor spends on your website. The question you’re trying to prove statistically is whether there’s an average increase in the amount of time spent on your website this week as compared to last week (as a result of your fancy new blog post). You can run the same statistical test I illustrated above to find out. Incidentally, it matters very little to the stat test whether the quantity of visitors differs or not.
Anyhow, the Data Analysis toolpack doesn't perform a lot of stat tests that folks like me would like to have access to. In those cases I have to either use different software, or write some very complicated mathematical formulas. Having this p-value formula makes my life a LOT easier!
Thanks!
Eric~
Fantastic stuf..One line explanation is cool.
Thanks to all the contributors
OS
Take FirstName, MI, LastName in access (you can fix it to work in excel) capitalize first letter of each and lowercase the rest and add ". " if MI exists then same for last name:
Full Name: Format(Left([FirstName],1),">") & Format(Right([FirstName]),Len([FirstName])-1),"") & ". ","") & Format(Left([LastName],1),">") & Format(Right([LastName],Len([LastName])-1),"<")
I teach excel, access, etc etc for a living and i have my access students build this formula one step at a time from the inside out to show how formulas can be made even if it looks complicated. Yes I know I could just do IsNull([MI]) and reverse the order in the Iif() function but the point here is to nest as many functions as possible one by one (also I illustrate how it will fail without the Not() as it is)
Extract the month from a date
The easiest formula for this is =MONTH(a1)
It will return a 1 for January, 2 for February etc.
if in a column we write the value of total person for eg. 10 if we spent 1.33 paise each person then how we get total amount in next column and the result will in round form plzzzzz solve my problem sir................... thank u
@Anjali
If the value 10 is in B2 and 1.33 paise is in C2 the formula in D2 could be =B2*C2
If the values are a column of values you can copy the formula down by copy/paste or drag the small black handle at the bottom right corner of cell D2
kindly share with me new forumulas.
