- * Data preprocessor used for preformatting a data.
- *
- * A data preprocessor is used in cases where a value from a dataset or label must be
- * displayed in another format or way than entered. This could for example be the need
- * to display X-values as a date instead of 1, 2, 3, .. or even worse unix-timestamps.
- * It could also be when a {@link Image_Graph_Marker_Value} needs to display values as percentages
- * with 1 decimal digit instead of the default formatting (fx. 12.01271 -> 12.0%).
