yError2 API Reference

# yError2.aggregate(value)

Aggregation function for the field (e.g., "mean", "sum", "median", "min", "max", "count").

Default value: undefined (None)

See also: aggregate documentation.

# yError2.argmax(field)

Apply the argmax aggregate operation prior to encoding.

# yError2.argmin(field)

Apply the argmin aggregate operation prior to encoding.

# yError2.average(field)

Apply the average aggregate operation prior to encoding.

# yError2.bandPosition(value)

Relative position on a band of a stacked, binned, time unit, or band scale. For example, the marks will be positioned at the beginning of the band if set to 0, and at the middle of the band if set to 0.5.

# yError2.bin(value)

A flag for binning a quantitative field, an object defining binning parameters, or indicating that the data for x or y channel are binned before they are imported into Vega-Lite ("binned").

• If true, default binning parameters will be applied.

• If "binned", this indicates that the data for the x (or y) channel are already binned. You can map the bin-start field to x (or y) and the bin-end field to x2 (or y2). The scale and axis will be formatted similar to binning in Vega-Lite. To adjust the axis ticks based on the bin step, you can also set the axis’s tickMinStep property.

Default value: false

See also: bin documentation.

# yError2.ci0(field)

Apply the ci0 aggregate operation prior to encoding.

# yError2.ci1(field)

Apply the ci1 aggregate operation prior to encoding.

# yError2.count()

Apply the count aggregate operation prior to encoding.

# yError2.date(field)

Apply the date timeUnit operation prior to encoding.

# yError2.day(field)

Apply the day timeUnit operation prior to encoding.

# yError2.distinct(field)

Apply the distinct aggregate operation prior to encoding.

# yError2.field(value)

Required. A string defining the name of the field from which to pull a data value or an object defining iterated values from the repeat operator.

See also: field documentation.

Notes: 1) Dots (.) and brackets ([ and ]) can be used to access nested objects (e.g., "field": "foo.bar" and "field": "foo['bar']"). If field names contain dots or brackets but are not nested, you can use \\ to escape dots and brackets (e.g., "a\\.b" and "a\\[0\\]"). See more details about escaping in the field documentation. 2) field is not required if aggregate is count.

# yError2.timeUnit(value)

Time unit (e.g., year, yearmonth, month, hours) for a temporal field. or a temporal field that gets casted as ordinal.

Default value: undefined (None)

See also: timeUnit documentation.

# yError2.timeYM(field)

# yError2.title(value)

A title for the field. If null, the title will be removed.

Default value: derived from the field’s name and transformation function (aggregate, bin and 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., "Profit (binned)", "Transaction Date (year-month)"). Otherwise, the title is simply the field name.

Notes:

1) You can customize the default field title format by providing the fieldTitle property in the config or fieldTitle function via the compile function’s options.

2) If both field definition’s title and axis, header, or legend title are defined, axis/header/legend title will be used.
