Inconsistency between date / time and solar longitude

[Molau]

Meteorflux.io has the option to prepared single year plots (which are printed against the date) and multi-year plots (which are printed against the solar longitude). However, the binning seems to differ in the two modes. Even when I take the same data from one year and the same settings, I get a slightly different results whether or not I activate the “average the selected years” box. That´s a little annoying when preparing a report with mixed graphs.
