This index is used by the roles variable in OnGraphDraw, and indexes the information about a graphing role filler dimension.

Index GraphFillerInfo

The roles variable in OnGraphDraw contains information about the graphing dimensions depicted on a graph. Roles is indexed by GraphingRole and by GraphFillerInfo. Each graphing role may by filled by a graphing dimension (either an index or a value), and information about that graphing dimension is indexed by GraphFillerInfo.

The filler information that is provided (the elements of GraphFillerInfo) are as follows:

  • "Type": The type of this graphing dimension, either "Index", "Value" or Null.
  • "Source": Usually a Handle to the variable that corresponds to this dimension. This will be true for an index dimension, the main result, and a comparison variable. Less commonly, a filler may be the result of a computed expression, in which case this contains a parsed expression.
  • "Slice index": The comparison index, if there is one.
  • "Slice position": The 1-based position along the comparison index of this graphing dimension.
  • "Categorical": Boolean, true when this graphing dimension is categorical (i.e., not continuous).
  • "Min", "Max": The smallest and largest values in an axis scale.
  • "Log scale": True when the axis uses a log-scale.
  • "Log abs min": When the axis uses a log scale, the smallest absolute value of non-zero data.
  • "Rounding unit": (for internal use)
  • "Reversed": Boolean. True when the order of the axis values or key values are reversed.
  • "Labels": The individual labels in a categorical dimension. For a categorical value dimension, this will be the set of unique values, in the order determined by the domain and other factors.
  • "Value": A reference to the computed value for this dimension (i.e., the data being depicted). In general, this is an array that may have multiple indexes.
