Altitude
The conversion factor and the label that you want all distances to display in. Conventionally, the conversion factor is converting from meters by default, but other values could be passed, like "1,KM" to use an unaltered value in kilometers.
Must be in the form conversionFactor,label. So for example converting meters to feet would be "3.28084,FT". The helper class {@link DistanceUnit} can be used. Currently only effective for multi-point graphics.
