Question Gantt Like Chart

[VentureFree]

I need to display a productivity chart for a call center and I'm thinking that a Gantt like chart would be the best way. There are four different "layers" of info that I need to show, and I'm thinking that I want to display it something like the following:

Time       |  9    10    11    12    1    2    3    4    5  |
Scheduled  | ********************************************** |
Clocked In |*******************    *************************|
On Phone   | **  ******   ****      ****  ***  *****  ****  |
Misc       |          *****                        ****     |

The hope is to use color coding to make it easy to read. For instance, there are many different things that can be considered "Misc" and each has it's own color code (already defined). Is there an existing control that can do something like this for me? If not, what would you recommend I do to create something like this? Thanks.
