One of the most common comments we get here is “how does xxx formula works?” Even though there is vast documentation on excel formulas including the built-in help in MS Office, often it is difficult for us to learn a formula quickly and use it in a snap. So to help new users of excel learn the most frequent formulas I have built an excel formula helper page.
The page currently lists about 50 most commonly used excel formulas along with 1 index card for each to explain,
- what the formula does
- what is its syntax
- 2 examples to understand how it works
see an example:
The good thing about these index cards is, they use simple day to day English to explain the formulas, so I am guessing they are a great way for new users to learn and use the formulas.
I have tried to keep the page simple so that anyone can come and learn a few formulas quickly. Play around with it and let me know if this is useful (of if something is funny / broken)
Here is the link: excel formula helper – 50 day to day formulas explained in plain English

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!
