The value of RANGE specifies the range of data values to be shown, starting from the ORIGIN value. The value of RANGE specifies the relative location in the coordinate plane of the right (if CURRENT AXIS is "X") or top (if CURRENT AXIS is "Y") edge of the viewing window (assuming that the value of the ORIENTATION attribute is "UP" or "VERTICAL").
The value of RANGE can be either positive or negative and the chart will be drawn appropriately. As such, this attribute can be used to effectively flip the chart over. If the LOGARITHMIC attribute is turned on (value is 1), the value of RANGE specifies the number of decades that the window will display. Do not set the value of RANGE to 0. Doing this will cause an error.
