I am using 2.6.2 and our requirement is to display asterisk in place of missing bars. I tried replacing null values with asterisk in afterDatasetFilled function, but chart does not display non-numerical characters.

Replacing the null value with zero and suffixing it with asterisk in the chart option produced a bar with height 1, which was not acceptable.

Attached is a screenshot of how the chart needs to look based on our requirement.

Thanks in advance

If you can replace the null value with a value that will not show up in
your dataset then you could use a bit of script to hide the bar and
replace the label with an *. Take a look at the attached example.

If you want you could also use this feature:
http://www.eclipse.org/birt/phoenix/project/notable2.6.php#jump_8
set your null values to 0 and then use the same script in the above
example to hide the bar and change the label.
