VBA Chart Title Difficulties

I have a pivot table which I update on a regular basis. There's also routine during the pivot table refresh to assign variables to the minimum and maximum dates I include in the range.

Here's what I'm looking for - The chart title needs to be two separate lines. It should look something like this:



Labor Operations performed from min_date to max_date
(labor op code, description, total ops)

By themselves, I have no problem doing this. What I can't figure out is how to format the font of the first line of the title to have different characteristics from the second line. The second line is sort of a descriptor of the part in bold (in an attempt to keep my boss from asking me questions about what he's looking at)
