We make charts with date axis all the time. For example, lets say you want to plot the number of donuts consumed per month in a chart, like this:
2 things become quite obvious when you look at this chart,
- The year -09 and -10 repeating across bottom of axis is pure chart junk.
- Aww, dude. How many donuts do you eat!?!
Now, there is nothing much I can do about donut consumption. But I can tell you how to fix that axis so it looks a lot better, may be like this:
Interested? Follow this simple recipe:
- Process your data: Assuming your data looks like what I shown to left, just use simple formulas to make it look like the table to right. [related: how to work with dates & times in excel]
- Now, make a chart from the data. Use both year and month columns for axis label series.
- That is all. Excel shows nicely grouped axis labels on your chart.
Pretty simple, eh?

2 Bonus Tips:
1. This technique really works with just any types of data.
So you can just have Product Group & Product Name in 2 columns and when you make a chart, excel groups the labels in axis.
2. Further reduce clutter by unchecking Multi Level Category Labels option
You can make the chart even more crispier by removing lines separating month names. To do this select the axis, press CTRL + 1 (opens format dialog). From Axis options, un-check Multi Level Category Labels option.
How do you format date axis on charts?
Most of the times when I make charts with date axis, the axis has 12 or 13 months of data. So I knock off the year part completely. But in some cases, I end up making charts that show data from multiple years. Now, repeating year value across bottom is a waste of chart ink. So I tend to use the above technique to make the chart look much more professional.

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!
