disturbing chart presentation when start of series (30 min vs 5 min) are misaligned

misaligned data:

wonder if it's because most of the series start at 9.05, whereas the solar series starts at 9.00:

@chienleng and @nc9 how do we want to solve this?

1. FE: skip the first rooftop data point (30 min aligned) if the rest of the data points (5 min aligned) aren't available
2. BE: tweak 7d.json to pull back the start date on the 5 minute fuel techs to align with the first rooftop data point
3. something else?

if we tweak the data, as in 2 above, then the data will cover slightly more than 7 days — so we'll need to trim the data (depending on whether the user is viewing 5 min or 30 min resolution) to ensure accuracy.

I've got this happening locally at the moment - it's not too bad a change. I'm just going to test it to work out what the impacts are on API endpoints and elsewhere
