[reportlab-users] BarLabelFormat

[Dirk Datzert]

Hi Marcus,

in one of your previous mails you told us that your code is defined this
way:

def _formatHour(self, seconds):
      # the code above

from an other mail on this list the example definition was:

def _formatHour(value):
  return doSomethingWith(value)

Your problems result in different definition !

>From the code of barchart.py line 311:

                if labelFmt is None:
                        labelText = None
                elif type(labelFmt) is StringType:
                        labelText = labelFmt % self.data[rowNo][colNo]
                elif type(labelFmt) is FunctionType:
                        labelText = labelFmt(self.data[rowNo][colNo])
                elif isinstance(labelFmt, Formatter):
                        #these are callable objects
                        labelText = labelFmt(self.data[rowNo][colNo])
                else:
...

labelFmt will be your function and will always called with 1 argument -
the value of the data-point

My suggestion don't define your format-function with self-referenced !

Regards,
Dirk
