That's not what I'm hoping to do. I want to format the dates that are
displayed on the horizontal axis of the actual column chart. What you
suggested changes the date format on the control, not the chart (and that
only works because in the control columns we don't convert the first one
from date to string). As mentioned, if I could pass in the format I want
('MM/dd') to the getFormattedValue() call, that would be sufficient, but I
don't think you can do that. I'm just hoping that there is an equivalent
way to choose the formatting before all the dates get turned into strings.
