GTILE Procedure

Missing Values, Negative Values, and Zero Values

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.
