# 2.2.3.9 Series

**Office**

A **series** is of a set of related **data points**
(section 2.2.3.10) that
are plotted in a **chart** (section 2.2.3.3). In addition to
specifying the **data points** of the **series** and the formatting
properties of the **data points**, a **series** can also specify a series
name and properties of the **data label** (section 2.2.3.11) and legend entries that are
associated with the **series**.

A **series** is defined by a sequence of records that
conforms to the **SERIESFORMAT** rule (section 2.1.7.20.1) specified by
the **chart sheet substream** (section 2.1.7.20.1) ABNF that contains a **SerToCrt**
record (section 2.4.256).

A **series** can either be of type included or excluded.
Included **series** are **series** that are shown in the **chart**.
Excluded **series** are not shown in the **chart**, but exist as **series**
in the file. A **series** is an excluded **series** if both of the
following conditions are satisfied:

The

**chart group**(section 2.2.3.7) type of the**series**is bar of pie, pie, or pie of pie.The

**series**is not the first**series**in the**chart sheet substream**to be on the**chart group**and contain in the second sequence of records that conform to the**AI**rule (section 2.1.7.20.1) a**BRAI**record (section 2.4.29) that contains an**ifmt**field that specifies a**formula**(section 2.2.2) that equals to a row or column that is not excluded from the**chart sheet**.

This occurs when the **chart group** is of type bar of
pie, pie, or pie of pie, and the **chart sheet** contains multiple **series**,
because these **chart group** types will only display the first **series**
of data on the **chart**.

All other **series** are included **series**.

The following records and rules define the significant parts
of a **series**:

The **Series** record (section 2.4.252) specifies the
type and size of the data in the **series**.

The four sequences of records that conform to the

**AI**rule specify**formulas**. The meaning of the**formulas**are specified as follows:In the first sequence, the value of the

**formula**specifies the name of the**series**. The**SeriesText**record (section 2.4.254) specifies a cache of the name of the**series**.In the second sequence, the value of the

**formula**specifies:A set of coordinates along the vertical value

**axis**(section 2.2.3.6) if the series is in a bubble or scatter**chart group**.A set of coordinates along the value

**axis**if the series is in any other**chart group**type.

In the third sequence, the value of the

**formula**specifies:A set of coordinates along a horizontal value

**axis**if the**series**is in a bubble or scatter**chart group**.A set of category (2)

**axis**labels that are distributed evenly along the category (2)**axis**based on their order in the set or a set of dates along a date**axis**is in any other**chart group**type.

In the fourth sequence of records, the value of the

**formula**specifies a set of scalar values used in a bubble**chart group**to define the size of the bubbles.

The sequence of records that conform to the

**SS**rule (section 2.1.7.20.1) specify the**data point**and**data label**properties for a**series**or individual**data points**of the**series**. If formatting is not specified for an individual**data point**, the**data point**inherits the formatting of the series. If formatting is not specified for the**series**, the**series**inherits the formatting of the**chart group**that contains the**series**. The**yi**field of the**DataFormat**record (section 2.4.74) MUST specify the zero-based index of the**Series**record associated with this**series**in the collection of all**Series**records in the current**chart sheet substream**that contains the**series**. Refer to the**data label**overview for an explanation of the**data label**and the conditions on this collection of records.The

**SerToCrt**record (section 2.4.256) specifies the**chart group**that contains the current**series**.The

**LegendException**record (section 2.4.153) specifies a legend entry in the**legend**(section 2.2.3.8) that corresponds to the**series**. If the**LegendException**record (section 2.4.153) specifies that the legend entry has non-default formatting, then the**attached label**(section 2.2.3.15) and the sequence of records that conforms to the**TEXTPROPS**rule (section 2.1.7.20.1) that follow the**LegendException**(section 2.4.153) and**Begin**(section 2.4.17) records specify the custom formatting of the legend entry. If the**fLabel**field of**LegendException**equals 0, the**attached label**MUST NOT exist.
