EMF file as destination

• During the next call to grDraw, the chart will be drawn in the <Name of EMF file> file.
• This file can be read by a tool that recognizes the EMF format.
• The size of this file can be defined by grWndSize.
• We recommend that you preview the chart before it is saved in a file.
• We recommend that you use grDestinationEMF rather than grDestinationWMF.

Differences between grDestinationEMF and grSaveEMF

• grDestinationEMF is used to define the destination of the next chart drawing. When grDraw is used, the chart will be drawn in the specified file and all the changes made since the chart was last drawn will be taken into account.
• grSaveEMF is used to save the chart in a file in EMF format. The image saved corresponds to the chart during the last call to grDraw. The changes made to the chart since grDraw was last called will be ignored.

Limits

• This function cannot be used with the Chart controls.
• This function cannot be used in the report editor.
• 3D chart: This function cannot be used: the DirectX software, used to handle the 3D charts, does not allow you create files in EMF format.

Creating and drawing a chart through programming

• create the chart (grCreate),
• add data (grAddData, grStockAddData and grScatterAddDataXY),
• define the chart destination (grDestinationBMP, grDestinationControl, grDestinationEMF, grDestinationWnd and grDestinationWMF),
• define the chart destination with the following functions:
  • grDestinationBMP,
  • grDestinationControl,
  • grDestinationEMF,
  • grDestinationWnd,
  • Versions 19 and later
    grDestinationImage,
    New in version 19
    grDestinationImage,
    grDestinationImage,
  • grDestinationWMF.
• draw the chart (grDraw).
