It would be nice if there was an option for this chart type to specify the minimum bar size in pixels. I have a 24 hour timeline and events that only last a minute or two do not show up at all.
The use case I have is to chart all of the events that occur in my house (motion detectors, doors open/close, lights on/off, etc) but for events that only last a few minutes, the bars render to small to even know they are there or to mouse over them.
