Darren writes one of my favorite blogs – Problogger, it is a blog about blogging. It is super helpful for people like me who write, connect, share and sell online. A week back, Darren asked his readers to participate in a fun experiment by posting 7 links on their blogs. It seemed like an interesting idea, so I am chipping in.
1. My First Post on Excel: While this blog is in existence since 2004, I did not start writing about excel until 2006. My first post on excel is How to remove duplicates. This was not written on chandoo.org, but on my excel blog r1c1.blogspot.com which I later imported here.
2. The post I enjoyed writing most: Now, this is difficult to choose. Because, writing is not what I enjoy most. My enjoyment comes when an article generates a lot of conversation (comments, discussion on other blogs etc.). To that extent, the most enjoyed post is Become a Conditional Formatting Rockstar.
3. Post(s) that had great discussion: I am proud of our community here. Most of the posts generate quite a bit of discussion and sharing of ideas. Here is a list of posts that had lots of insightful comments:
- Do you know these double click tricks? – 86 comments
- Introduction to VLOOKUP, MATCH and OFFSET formulas – 75 comments
- Become a Conditional Formatting Rockstar – 180 comments
- Calculating Days Overlapped Between 2 sets of dates – 46 comments
- Childhood dream comes true – story of Chandoo.org – 86 comments
- Excel Keyboard Shortcuts – Open Thread – 66 comments [read followup Comprehensive list of keyboard shortcuts in Excel which consolidates all these shortcuts in to one post]
4. A post on someone else’s blog that I wish I’d written: 2 posts come to mind. First one is Debra’s unbelievably comprehensive collection of Pivot Table tips & tricks. Next one is Jon’s detailed overview of number formats in excel. Both of them are very well structured, highly sought after topics that I wish I had written. I refer to them every now and then when I am stuck and need help.
5. A post title that I am most proud of: Hands down it has to be Want to be a conditional formatting rock star? Read this. But I also like Twins, Clones and Duplicates – 6 Excel Shortcuts from an Excited Dad which I wrote from hospital room when I became dad to twins in Sept, 2009.
6. A post I wish more people had read: hmm, it could be the Date with my sheet – 10 tips on using date / time in Excel, which despite having a lot of tips, never really took off.
7. Most read post ever: It has to be the Gantt Charts – Project Management using Excel post. Written on June 16th, last year, the post attracted 150k page views so far, with 63 comments. The post also played a crucial role in 630+ sales of Project Management Templates.
One Question for you:
What is your most favorite post on Chandoo.org and why do you like it? Please share using comments.
PS: If you are not in mood for excel, here is something to get you excited. Some one calls me a bastard and it made me laugh. Find out why.

While this works in a pinch, it clearly "lightens" the colors of the entire chart. Depending on where you use this, it will be blatantly obvious that you don't know what you are doing and present a poor looking graph.
Why not separate the data into different segments when charting and have as many colors as you have data points? You might have to create a new legend and/or repeat the chart in "invisible ink", but it would be cleaner and more consistent when new or updated data becomes available.
While I think I agree that doing it "properly" via a second series is preferable, I don't necessarily agree that making the entirety of the "future" (data, gridlines, and even the axis) semi-transparent is "poor looking". I think it could be seen as adding more emphasis to the "future-ness" of the forecast data.
In short, it's another tool for the toolbox, even if it's never needed.
Simply and clever 🙂
Quick & effective, cool. thanks.
I always use the dummy series.
Nice little trick, thanks very much!
Two sets of data better. Control is much better.
You can use the same chart next month to see what is actual and what is forecast.
To use this trick, I think grid lines has to be removed, that will make the graphic much more sharp.
to be honest, i dont understand why there is needed to do this way... in this case horizontal lines will be pale as well. then why a just can't change the color of the line partly???
Great tutorial. Thanks for the tutorial!
