12.3.8 Drawings Part

An instance of this part type contains the presentation and layout information for one or more drawing elements that are present on this worksheet.

A package is permitted to contain one or more Drawings parts, and each such part shall be the target of an explicit relationship from a Worksheet part (§12.3.24), or a Chartsheet part (§12.3.2). There shall be only one Drawings part per worksheet or chartsheet.

[Example: The following Chartsheet part-relationship item contains a relationship to a Drawings part, which is stored in the ZIP item ../drawings/drawing1.xml:

<Relationships xmlns="...">
  <Relationship Id="rId1" 
    Type="http:// .../drawing" Target="../drawings/drawing1.xml"/>
</Relationships>

end example]

The root element for a part of this content type shall be wsDr.

[Example: drawing1.xml refers to a chart that is the target of a relationship in the Drawing part's relationship item:

<xdr:wsDr xmlns:xdr="..." xmlns:a="...">
  <xdr:absoluteAnchor>
    <xdr:pos x="1518046" y="-1443632"/>
    <xdr:extents cx="8587382" cy="5848945"/>
    <xdr:graphicFrame macro="">
      <xdr:nvGraphicFramePr>
        <xdr:cNvPr id="24" name="Chart 24" descr=""/>
        <xdr:cNvGraphicFramePr/>
      </xdr:nvGraphicFramePr>
      <xdr:xfrm>
        <a:off x="0" y="0"/>
        <a:ext cx="0" cy="0"/>
      </xdr:xfrm>

      <a:graphic>
        <a:graphicData uri="http://.../chart">
          <a:chart relId="rId1"/>
        </a:graphicData>
      </a:graphic>
    </xdr:graphicFrame>
    <xdr:clientData/>
  </xdr:absoluteAnchor>
</xdr:wsDr>

end example]

A Drawings part shall be located within the package containing the source relationship (expressed syntactically, the TargetMode attribute of the Relationship element shall be Internal).

• Chart (§14.2.1)
• Diagrams: Diagram Colors(§14.2.3), Diagram Data(§14.2.4), Diagram Layout Definition(§14.2.5) and Diagram Styles (§14.2.6)
