When the GTILE procedure
finds missing values, negative values, or zero values, it does the
following:
-
The chart's size variable requires
nonmissing, positive values to create a tile for that observation.
If the value of the size variable is missing, a negative value, or
a zero value, the observation is not included in the chart.
-
The TILEBY= variable displays tiles
with missing values, negative values, and zero values. Each tile is
included in the chart, with its value displayed on the tile and in
the chart's data tip.
-
The COLORVAR= variable displays
missing values in a color that can be distinguished from the colors
in the color ramp.
Note: For Java, an indicator to
the right of the legend identifies the color assigned to missing values.
