virtual |
The text properties used to label the lines.
Note that both vertical and horizontal justifications will be reset to "Centered" prior to rendering.
If the TextPropertyMapping array exists, then it is used to identify which text property to use for each label as follows: If the scalar value of a line is found in the mapping, the index of the value in mapping is used to lookup the text property in the collection. If there are more mapping values than properties, the properties are looped through until the mapping is exhausted.
Lines with scalar values missing from the mapping are assigned text properties in a round-robin fashion starting from the beginning of the collection, repeating from the start of the collection as necessary.
