Here is a cool count-down timer application made in VBA to remind you about our VBAClasses registration closing time!
I know it is blindingly awesome. So I will give you a few seconds before reading further.
….
Back already? Great.
I was thinking of ways to tell you that you have got less than 3 days to join our VBA Class. Then it struck me, why not make an Excel workbook to tell you how much time you have got? So I did just that.
Here is a video demo of how the VBA application works (watch on YouTube):
Download the VBA Classes Count-down Timer Workbook:
Click here to download the workbook. Please enable macros to see it.
PS: You must drag and drop this file in to Excel 2007 or above to see it.
How does the Count-down Timer Work?
First, I must tell you about its limitations:
- This workbook assumes that your computer is located at the hotspot (or city) you have chosen.
- The current time is fetched from your computer’s local time using NOW() formula.
Now, the basic construction of this workbook can be broken down to 3 parts:
- Hotspot / City Selection
- Countdown Timer
- Formatting
Hotspot / City Selection:
- I took an outline map of world and put it in an empty sheet. On top of this I have added 9 hotspots by drawing nine circles.
- I have named these hotspots spot1, spot2…,spot9
- As you can guess, each of these spots correspond to one time zone, from PST to Australian Time.
- I have assigned macros to each of them. The macros would just modify a cell named valSpot with the name of the spot on which I clicked.
- Based on the clicked spot, I fetched the corresponding closing time from a table like this:
- Then, I calculated the time left by subtracting current time from closing time.
- A similar logic is used for City selection.
Countdown timer:
- I have inserted a check box and linked it to a cell named showTimer
- I have also assigned a macro startTimer to the checkbox.
- The startTimer macro would call a different macro named – countDownTime()
- In this, I wrote a while loop that would check if the showTimer is true and ask Excel to update the currentTime once every second
- The code can be examined from the downloaded file.
Formatting:
I am leaving this to your imagination.
Bottom line: Join our VBA Classes
Of course, the whole point of this is very simple.
If you want to learn VBA, then please join our VBA classes. We will be closing registrations in 3 more days. After that we will be busy for next few months teaching VBA to those of you who joined us.

PS: When you join our VBA Class, you get to learn how this timer app is constructed in a detailed 40 minute lesson. That is just one of the many lessons in our class. So, join us already.

I think the virtue of pie charts is precisely that they are difficult to decode. In many contexts, you have to release information but you don't want the relationship between values to jump at your reader. That's when pie charts are most useful.

Chandoo,
millions of ants cannot be mistaken.....There should be a reason why everybody continues using Pie charts, despite what gurus like you or Jon and others say.
one reason could be because we are just used to, so that's what we need to change, the "comfort zone"...
i absolutely agree, since I've been "converted", I just find out that bar charts are clearer, and nicer to the view...

Chandoo -
You ask "Can I use an alternative to pie chart?"
I answer in You Say “Pie”, I Say “Bar”.
This visualization was created because it was easy to print before computers. In this day and age, it should not exist.
I think the 100% Bar Chart is just as useless/unreadable as Pies - we should rename them something like Mama's Strudel Charts - how big a slice would you like, Dear?
My money's with Jon on this topic.
The primary function of any pie chart with more than 2 or 3 data points is to obfuscate. But maybe that is the main purpose, as @Jerome suggests...
@Jerome.. Good point. Also sometimes, there is just no relationship at all.
@Martin... Organized religion is finding it tough to get converts even after 2000+ years of struggle. Jon, Stephen, countless others (and me) are a small army, it would take atleast 5000 more years before pie charts vanish... patience and good to have you here 🙂
@Jon .. very well done sir, very well done.
good points every one...
I've got to throw my vote into Jon's camp (which is also Stephen Few's camp) -- bars just tend to work better. One observation about when we say "what people are used to." There are two distinct groups here (depending on the situation, a person can fall in either one): the person who *creates* the chart and the person who *consumes* the chart. Granted, the consumers are "used to" pie charts. But, it's not like a bar chart is something they would struggle to understand or that would require explanation (like sparklines and bullet graphs). Chart consumers are "used to" consuming whatever is put in front of them. Chart creators, on the other hand, may be "used to" creating pie charts, but that isn't an excuse for them to continue to do so -- many people are used to driving without a seatbelt, leaving lights on in their house needlessly, and forwarding not-all-that-funny anecdotes via email. That doesn't mean the practice shouldn't be discouraged!

Good article. Is it possible to do that with line charts?
Hi,
Is this available in excel 2013?
