specifying the width of a sparkline result

How to pass the parameter "width" to the sparkline format.

I see that width defaults to auto in ./resources/jquery/jquery.sparkline.js (line 234 section "Default configuration settings")

I was able to hack that default from "auto" to "150px" and it works, but how to do this from the smw #ask statement?
