Step charts are a good idea. Handling missing data in general is a bit tricky and I haven't full thought through the problem. The real-time charts are build with a timestamp component which, given a specific time granularity (second, minute, etc.), could be used to handle gaps. Basic charts might require an option to switch on/off such behavior. In case you're interested, I've opened up a new issue in the repository: https://github.com/fastly/epoch/issues/64 Thanks for the great suggestion!

Hi, I'm Ryan, I wrote Epoch. Yes, I agree hover support would be nice. My take on the initial release was that I wanted to keep it super simple. So I decided that we should first build out the basic charts without any bells or whistles. To aid developers who need more than just the basics I also built out a small class hierarchy that allows you to override / modify the default chart behaviors. It's pretty clear that library needs better support for features like this moving forward. At the very least, there should be consistent and straightforward way to extend Epoch to help with these sorts of things. If anyone is interested in continuing the discussion I've opened up a new issue in the repository specifically targeting hover behaviors: https://github.com/fastly/epoch/issues/63
