I'm looking for a nice way to present a timeline with something seemingly simple; whether a machine is (was) on/off (up/down).
My dataset has 1 entry per minute with TRUE/FALSE for up/down.
Most chart scripts are able to handle serious complicated datasets in multiple flavours, but not simple on/off stuff.
I'm already using Highcharts and Highstock on my site. While I'd prefer to use that, I'm absolutely open for any alternatives or even complete different solutions.
