A while ago, we published a new year resolution template. This was a hit with our readers with thousands of you downloading it. During last week, Peppe, one of our readers from Italy, took this template and made it even more awesome.
The original template had tasks and completion check marks. As you finish each task, you can see overall progress too.
Peppe added priorities to this. With his new version, progress is measured based on how much priority we assigned that particular task. Pretty neat eh?!?
Personal Todo list with Priorities – Demo
First take a look at Peppe’s todo list.

How is this made?
Using lots of Excel goodness of course. The basic components of this todo list are,
- Check boxes – to mark each activity as done (or not done)
- Data validation – to assign priority (1 to 5) to each activity
- Conditional Formatting – to highlight a row when the activity is marked as done
- Thermo-meter chart – to show the progress as you mark each activity done
- Formulas – to calculate % done based on how many activities are done & their priorities.
Since first 4 items are already explained on Chandoo.org, let me focus on the formula part.
Calculating % completion based on priorities:
To understand this problem, lets imagine, we have 5 tasks & priorities like below:

Step 1: Calculating weights
First step is to calculate how much weight each task should get. This is a simple job of inverting priority values (1/priority value). We will get this.

Step 2: Calculate weights to 100%
Next, we adjust the weights so that their total is 100%. To do this, we just divide a task’s weight by total of all task weights.

Step 3: Calculate % done only if a task is marked as done
Now, we just use TRUE / FALSE values generated by the check boxes to calculate % done. For this, we just need to multiply 100% weights with TRUE or FALSE values.

The total of this column gives us how much % of all tasks are done.
Note on weights for priorities
In this approach, we are assuming that doing one priority 1 task gives same output (%done) as doing two priority 2 tasks, three priority 3 tasks etc.
That means the weight enjoyed by priority 1 task is twice that of priority 2 task.
Some other possibilities are,
- Priority 1 is 1, 2 is 0.8, 3 is 0.6…
- A mapping table telling us how much each priority weighs
Read weighted averages in Excel to understand more.

Thank you Peppe
I find this template quite simple, yet powerful. It shows how much we can do with Excel by using a little creativity, simple features (conditional formatting, form controls etc.) and a some motivation.
Peppe, Thank you so much for sharing this with us.
If you enjoyed this todo list template, go ahead and say thanks to Peppe.

Hi Chandoo
As one of your students I have followed your detailed example through with great success. However, Excel is acting in an unexpected way and I wonder if you could take a look?
http://cid-95d070c79aef808e.office.live.com/self.aspx/.Public/Gantt%20Box%20Chart.xlsm
On my version, I have to type 40239 (Which equates to 2 Mar 2010) to get the chart to display 31 May 2010 (which should be 40329)!!??
Have I done something wrong or is Excel acting up?
Thx
Oli
PS Your example file in 2007 displays correctly.
Hi,
I like this idea a lot, but I agree the name is a little drab.
As an American I may just be seeing things, but to me the combination of lines and bars on your chart looks like a bunch of cricket bats.
Maybe you could work that into a catchier name. 🙂
Cheers!
Here is some code I use to keep the axis synched.
It may be useful to some of your readers
It is based on a comment I saw on Daily Dose of Excel.
Function SynchGanttAxis(Cname, lower, upper)
'Sets the X min and X max for Category axis
Application.Volatile
On Error Resume Next
'
'Top Horizontal Axis
With ActiveSheet.Shapes(Cname).Chart.Axes(xlCategory, 1)
.MinimumScale = lower
.MaximumScale = upper
End With
'Bottom Horizontal Axis
With ActiveSheet.Shapes(Cname).Chart.Axes(xlValue, 2)
.MinimumScale = lower
.MaximumScale = upper
End With
End Function
Function SynchVerticalAxis(Cname, lower, upper)
Application.Volatile
On Error Resume Next
' Excel 2007 only
'Right hand vertical axis
With ActiveSheet.Shapes(Cname).Chart.Axes(xlValue, 1)
.MinimumScale = 0
.MaximumScale = upper
End With
End Function
@Oli.. Can you check your file again.. I see 40329...
@Dave: Even I saw things.. the bars actually looked like lollipops. How about calling this lollipop chart - now that would be yummy and goes along the tradition of naming charts after eatables (bar, pie, donut...)
@Bob: Superb stuff... thanks for sharing 🙂
Hi Chandoo
This looks really good and I think it can also be applied to show project phases / milestones.
Question: Thinking further could this be amended to display a project lifecycle (Idea through to Implementation say 7 phases) on one bar / row? Just imagine 20 projects within a programme all on one chart one bar each showing their respective lifecycle stages i.e. on one page.
Idea: As the Gantt Box Chart this is quite intensive to set up re formatting etc how about the added extra of once you have completed this to "Save as template" i.e. saves the formatting and layout of the chart as a template so you can apply to future charts. Simple to do and will save the time formatting etc again and again and again.
Therefore tip: Click on your chart demo and then click on Save As template icon (2007) - edit file name and click on save. Ready to use / apply via Templates in Change Chart Type window.
Thanks and be very interested if the lifecycle question can be resolved
Mike
How embarrassing.
I was obviously suffering from numerical dyslexia. I was one of those days.
@Mike H: You can easily make this chart to work like a generic project lifecycle plan chart. All you have to do is,
1. in a separate sheet define the steps of lifecycle and various dates in a table (with 5 columns for each of the projects you have).
2. now use a control cell to input the project name you want to show in the chart
3. based on the input, use OFFSET Formulas to get the correct data
4. Rest is same as the tutorial above

Your solution is really smart but in the en Excel isn't meant to do stuff like this. I, as a former PM, always thought is was frustrating that you had to do stuff like this for something simple like a Gantt chart. So I built Tom's Planner. And would like to plug it here. I think it really solves the problem you are trying to solve in the most efficient way. Check out http://www.tomsplanner.com for a free account or play around with the demo.
Hi there,
Chandoo - this is really a very nice and helpfull chart - I adopted it, so I can report a forecast or the delay of a certain task (coming from my role as an auditor for projects).
One topic I´m currently struggeling with: I do have a project lasting for lets say 12 month. For a management reporting, I want to have kind of snapshot, lets say one month back and 2 month in the future. I tried with the offset formula, but failed. Any idea?
Thx

Hi Chandoo - fantastic xls. One thing I can't figure out how to do is adjust the alignment of the vertical axis. I would like to left align so that I could indent to represent sub tasks. Can that be done? Or is there a better way?
I've been trying to work out if there's a way to show weekends on the graph. The closest thing I've got is to add them on a secondary axis, but then I haven't been able to keep both axis lined up together! Any ideas?
Following on from this - is it possible to show things like holidays?
