Title, Scale, Source and Alignment[edit]
Optional named parameters include title, scale and source.
- A title appears bolded and centered above the chart.
- A scale is needed for handling very small or large numbers.
- A source tells the viewer where the data came from.
title = Small numbers, large scale scale = 10 source = Data invented for this example.
{{Data bars
| title = Small numbers, large scale
| scale = 10
| source = Data invented for this example.

Also, to center or to float a chart left or right, specify center, right or left in parameter align (aka float). For example:
{{Data bars
| align = right
| columns = 6 | Jan| Feb| Mar| Apr| May| Jun
| blue|Berries| 65| 38| 72| 47| 20| 30
}}

Orientation, Borders, Details and Averages[edit]
There are sixteen styles to choose from.
- Odd numbered styles are vertical.
- Even numbered styles are horizontal.
- Styles 3 and 4 have borders and shading.
- Styles 5 thru 8 are the same as 1 thru 4, but show additional detail.
- Styles 9 thru 16 are the same as 1 thru 8, but averages are displayed with the color key, instead of totals.
For example, here's one using style=8:
| Horizontal, with borders, shading and visible detail.
|
{{Data bars
| style = 8
| scale = 0.1
| title = Fruit Amounts (lbs)
| source = Data invented for this example.

This template employs five "sub-templates." A table is created using the columns and rows of data.
- {{Data bars/bar}} draws each vertical or horizontal rectangle optionally colored and labeled with a name and/or a value.
- {{Data bars/column}} handles one column of data.
If style is > 8, the data is passed along to other sub-templates to display averages instead of totals with the color key.
- {{Data bars/averages}} calculates the averages of all the rows of data.
- {{Data bars/averages/display}} assigns the averages to named parameters for display as a single complex bar.
- {{Data bars/averages/column}} draws a vertical labeled bar of averages serving as a color key.
