Here is the big hairy question of the week. What is your opinion on Pie Charts?
Pie charts are one of the most used charts in the world. And for obvious reasons: they are simple to create and easy to understand.
When it comes to pie chart, I have no clear opinion. Part of me says use them, the other says avoid them. The debate about pie charts is not just internal. Last time when Seth Godin included pie charts in his 3 laws of great presentation,
The problem with bar charts is that they should either be line/area charts (when graphing a change over time, like unemployment rates) or they should be a simple pie chart (when comparing two or three items at the same scale).
there was so much furor in the data visualization blogosphere that Seth even did a follow up post comparing bars with pie charts, where he says,
The pie chart contains far less data, but the point is obvious: Trolls are where we should focus our energy.
That’s why you use it. …
I stepped on the toes of many data presentation purists yesterday, so let me reiterate my point to make it crystal clear: In a presentation … the purpose of a chart or graph is to make one point, vividly. Tell a story and move on.
Personally I think pie charts provide great utility at very little cost:
- They are very easy to create
- Very very easy to understand (provided the data has some contrast, if your numbers are like 43,44,45,46, there is little chance that anyone can understand the resulting pie chart and make out which one is large and which one is small)
But, I also think they are easy to abuse (one reason why you see way too many pie charts compared to other charts).
Here is what I think cripples a pie chart from being effective:
- Too many data points. A pie chart would probably be effective up to 4 values, anything more and you better have a strong story behind it for people to read and interpret. For eg. the pie chart shown to the right is used in Google Analytics reports. This compares browsers used by visitors of a site and even though there are probably hundreds of browsers, only 2 are prominent, so the pie still works.
Poor use of color. The purpose of color in most visualizations is to bring contrast. To separate apples from oranges. To throw light where your story lies. But most programs that are used to generate pie charts have poor (and often scary) color choices. When you use poor color combinations, the result will be drastic. But this blame is not on the person making pie charts, but on the pie chart software. See the example aside from clearlyandsimply to see what contrast means.- Making Pie charts that are difficult to compare. The purpose of pie charts is to provide comparison. So when we make a pie chart that has poor ability to compare, we are already lost. That means we should avoid all the flashy formatting, 3d pie charts, 3d donuts and layered donuts etc. Also, whenever possible, try Using data labels, using color and if nothing works, try using other types of charts for comparison. After all, we are not selling pie charts, we are selling our stories.
Ok, now the ball is in your court (or the pie is in your plate).
What do you think about pie charts?
Do you prefer them or do you consciously avoid them ?
How do you think pie charts can be put to better and greater use ?

Nice post! Invoicing for the small biz or solo entrepreneur is something I see a lot of interest in. Also there are great templates from http://office.microsoft.com/en-us/templates
This is awesome.
I would need a little more. e.g. say I generate a Inv. # 1 with all the details. Once done I can click a button all the relevant details gets stored in some table. Further, when i generate a new invoice those details gets stored in same table but just below the previous invoice.
Is their a way to do this?
I did create a solution you are looking for, however its wrapped in a larger 'Medical Scheduler' and it uses VBA, But you can Save, Update, Lookup, Email, Print & Apply Payments to the Invoice.
You are welcome to download it here:https://www.dropbox.com/s/2yvo0o2tgq9quhe/Medical_Massage_and_Salon_Application-Free.xlsm
The Invoice Items are created from the Appt. Types & Service Items table.
I would love all feedback from this
Thank you for sharing. I will definitely have a look at it.

Hi Chandoo,
Thanks for sharing this invoice template, Let me tell you this template will definitely help me since I got a process to handle where this invoice piece comes. Just a small doubt, can we store all the invoice details in PRODUCT & SERVICES sheet. So that whenever I select an invoice number from invoice sheet I can take print out and I can share it as well. Can we do that?? Since I will be dealing with this on monthly basis.
It would be great if you can help me with this.
Thanks in advance for your help!

Hi Randy, I tried to download one of your link "https://www.dropbox.com/s/2yvo0o2tgq9quhe/Medical_Massage_and_Salon_Application-Free.xlsm" However, i found the link unavailable. Can you please help me get the new link or can you please send this VBA file on my Email-ID.
Hello Anuj,
Thanks for alerting me to the broken link. This one should work:

Please let me know if you have any questions.

Thank you so much Buddy. will check and revert you soon.
Hi, is there any chance that this can work with the "Products & Service" sheet outside of the Invoice sheet. I create multiple invoice files for the numerous clients. Updating the product sheet for each of them maybe a task. Hence, I want to create a MASTER FILE from which data can be picked up without having to insert new data in each of the invoice files.
Possible? Or am I asking for the moon 😉
Thank you so much for tutorial.
This example can be reviewed for the example of the advanced invoice that made with excel userform :https://youtu.be/Qr-4of-38DI
Good Day

when you lookup a item code in the next column to the right it brings up the description then the quantity, unit cost, discount and then total otherwise i love the template
Item Code Description Quantity Unit Cost Discount Total
When creating an Invoice template in Excel are you able to utilize the auto row height and wrap feature when the cell is a merged cell? I need to have a number of cells merged together to allow for enough space to type in the description of work performed (lets say cells A-D are merged in each row) however it seems that I am unable to utilize the auto format feature. To work around this I have to manually increase the row height after each entry. Is there a better solution for this? Thank you!
