I have a bar charts layer, and some of the bar charts don't show up.
Strangely, when I'm using openlayers to display a zoom-and-pan map different
bar charts go missing at different levels of zoom. Is this a bug, or some
feature?
Here's a bit of my mapfile:
MAP
NAME "luzs-MAP"
# Map image size

UNITS meters
EXTENT -85.3382299999 33.1785600011 -83.5057259973 34.5140960012
PROJECTION

END

# Background color for the map canvas -- change as desired
IMAGECOLOR 255 255 255

END
skipping over to the bar charts layer definition:

etc.
