Bar & Column charts are very useful for comparison. Here is a little trick that can enhance them even more.
Lets say you are looking at sales of various products in a column chart. And you want to know how sales of a given product compare with a lower bound (last year sales) and an upper bound (competition benchmark). By adding these boundary markers, your chart instantly becomes even more meaningful.

How to create a chart with lower & upper bounds?
1. Select data and make a column chart
Lets say your data looks like this. Select it all and insert a column chart from insert ribbon.

2. Convert lower & upper columns to lines
In Excel 2013:
- Right click on either lower or upper bound columns.
- Choose “Change series chart type…”
- Select “line chart with markers” as the chart type for both lower & upper series
- Done!
In earlier versions:
- Right click on lower series
- Choose “Change series chart type…”
- Select “line chart with markers”
- Repeat the process for upper series
- Done

After this step, your chart looks like this:

3. Set line color to “no line” and format markers
This is easy. Just set the line color to “no line” and format the markers so that they are prominent.

Your column chart with lower & upper bounds is ready.
Bonus step: Custom shapes for lower & upper bounds
If you want something fancy, you can use custom shapes for lower & upper bounds, as shown below.

To get this:
- Draw custom shapes using drawing tools in Insert ribbon.
- Make sure they are really small (else the markers will be shown at wrong places)
- Copy the shape (CTRL+C)
- Select marker series for which you want this shape.
- Paste (CTRL+V)
- Done!!!
