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.

Noooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo!!
Whyyyyyyyy?
The idea is to tell how to make a bubble chart. I got an e-mail from a reader recently asking how the scatter bubble is made. So I thought a 15 second tutorial would be a good idea to show this.
Did that email go "Dear Chandoo, I know that you scorn bubble charts, but if I don't do one in Excel for my boss then he'll fire my sorry ass, and my children will have to be sold for medical experiments in order for me to be able to afford the upgrade path to Excel 2010"?
If so, fair enough...it's all in the greater good 😉
Chandoo,
I am using excel 2003 and it is not working. The x axis is not the one that I enter in x axis column. Please help! Thanks.
Sorry, after few attempts, I managed to get the right result. I shouldn't select the title (header) of the table and select only the data to produce the right bubble chart.
What's wrong with bubble charts? Is there a better method for displaying scatter plots with lots of overlapping data points? Don't tell me you'd rather jitter!
@Sanwijay: Cool.
@Precious Roy: There is nothing wrong with bubble charts. Infact, it is the only way to show 3 dimensional data (x,y and sizes) without confusing your audience. Jeff is worried that people might misuse the chart. As with any chart, bubbles also have a place and time for using them.
I recommend using bubble charts to show relative performance various products in several regions and similar situations.
Also, human eye is notorious in wrongly estimating the bubble sizes (as we have to measure areas). See http://chandoo.org/wp/2009/07/28/charting-lessons-from-optical-illusions/
We can partially improve bubble charts by adding data labels, but if you have too many bubbles, the labels will clutter the chart and make it look busy.
I can't seem to find a way to plot more than ten bubbles on a chart and need to know how to add more
@KW.. why would such a thing happen. I am sure you can add more bubbles that that. Can you tell us exactly what you are doing...
Example table:
A B C (size)
Me: 25 30 15%
Him: 30 22 11%
Her: 12 30 20%
I am trying to make a bubble chart where the Y axis is A, the X axis is B, and the size of the bubble is C. There should be only 3 bubbles. I keep ending up with six (with the labels being only "Me" and "Her"). My goal is to have three bubbles, one representing each person. Clearly I am doing something wrong. Can you help explain...?
Hi,
I wanted to add data labels to the bubbles. Each bubble represents a different company name. Excel allows me to add the size, legend, x axis values and y axis values. How do I add instead- Company A, B, C, D for the bubbles?
youon you have to choice every data for every company..
ex:create bubble for A company,after that click right> add data label> adjust data labels :format data labels and choose : series name.
i hop u will succeed .
[...] we create a bubble chart with 2 bubbles. 1 for the actual mustache & 1 for target [...]
If we want bubble size to be controlled by one column, but the bubble labels to be controlled by another column, how can this be achieved?
many thanks!!!!
