When I read Is your website’s underwear showing?, I couldn’t control the urge to write this one.
So the big screaming friday question everyone…
Is your chart’s underwear showing?
What is my chart’s underwear? you may ask.
My dear reader, it is the background color (that grayish shade excel adds by default). Also commonly known as one of the chart junk (no pun intended).
It is surprising how many people leave the default background color on, and yet spend countless hours working the rest.
What difference does it make?
It makes a hell of a lot of difference. Just set the background color to white and tell me if your eyes haven’t felt better.
Remember, only superman can get away showing his underwear. But, again he doesn’t have to work on spreadsheets and powerpoint like you and me. So, lets just hide that ugly background color. Ok?

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!
