Add encoding for xError2 to a vega-lite spec.

null, the title will be removed.
Default value: derived from the field's name and transformation function (
timeUnit). If the field has an aggregate function, the function is displayed as part of the title (e.g.,
"Sum of Profit"). If the field is binned or has a time unit applied, the applied function is shown in parentheses (e.g.,
"Transaction Date (year-month)"). Otherwise, the title is simply the field name.
You can customize the default field title format by providing the
