I have a log of data that is being populated that is associated with a piece of equipment. My log records the date and status (i.e. offline, online, in use, planned maintenance, and engineering) and I need to show this a some short of graph on Excel tied to VBA code I've already written to populate it. There are 140 machines that are operating at any given time and we want an overall view of the past six months of time up or down based on status and assigning it an associated color. This would just be an addition to the code I've already create. If you can get me started with one machine I'm sure that I can implement it with other machines
I've tried your basic excel graphs and they don't work with categorical variable like I have. I don't want to change the categorical "offline" to a numeric value if I don't have to.

For example
