I've created an image of what I would like to do. I've looked at the Scatter and Discontinuous examples, but I can't find something that seems right.
Basically all I want to indicate, is another event that took place at the time period. I have a start and end value.
As you can see from the image below I also tried a "vLine" between Categories, but I have no control over the exact position of the vLine and the exact thickness.
*Note this basically shows the uptime, and showing when another event impacted on the uptime is the goal of the Graph
