In the process of refactoring the interface between python and R to bring all date math into Python, several gross errors were introduced to the R calls in phlogiston.py. make_charts.py is supposed to be called twice, once with zoom = true and once with zoom = false. Instead, it was called twice with True. To make the category charts, make_tranche_chart.R should be called, but this was changed to make_charts.R. Also, make_tranche_charts.R was not fully updated to handle the new parameters.
