About the Input Data Set |

If you specify interpolation with a SYMBOL definition, by default values outside of the axis range are excluded from interpolation calculations and as a result may change interpolated values for the plot. Values that are omitted from interpolation calculations have a particularly noticeable effect on the high-low interpolation methods: HILO, STD, and BOX. In addition, regression lines and confidence limits will represent only part of the original data.

To specify that values out of range are included in
the interpolation calculations, use the MODE= option in a SYMBOL statement.
When MODE=INCLUDE, values that fall outside of the axis range are included
in interpolation calculations but excluded from the plot. The default (MODE=EXCLUDE)
omits observations that are outside of the axis range from interpolation calculations.
See the MODE= option of the SYMBOL statement in SYMBOL Statement for details.

If your data contain logarithmic values or if the data values vary over a wide range or contain large values, you may want to specify a logarithmic axis for the horizontal or vertical axis. Logarithmic axes can be specified with the AXIS statement options LOGBASE= and LOGSTYLE=. See AXIS Statement for a complete discussion.
