grDestinationWMF("MyChart", "C:\Charts\Chart.WMF")

Syntax

grDestinationWMF(<Chart name> , <Metafile name>)

<Chart name>: Character string (with quotes)

Name of chart to use, defined by grCreate.

<Metafile name>: Character string (with quotes)

Name of meta file where the chart will be saved. This metafile is created during the call to grDraw.

Remarks

Creating and drawing a chart by programming

To draw a chart:

create the chart (grCreate),
add data (grAddData, grStockAddData and grScatterAddDataXY),
define the chart destination (grDestinationBMP, grDestinationControl, grDestinationEMF, grDestinationWnd and grDestinationWMF),
draw the chart (grDraw).

WMF file for destination

During the next call to grDraw, the chart will be drawn in the meta file named <Name of Meta File>.
This file can be read by a tool that recognizes WMF format.
The size of this meta file can be defined by grWndSize.
We recommend that you preview the chart before it is saved in a file.

Differences between grDestinationWMF and grSaveWMF

grDestinationWMF is used to define the destination of next chart drawing. When using grDraw, the chart will be drawn in the specified file and all the modifications performed since the last chart drawing will be taken into account.
grSaveWMF is used to save the chart in a file in WMF format. The image saved corresponds to the chart during the last call to grDraw. The modifications performed on the chart since the last call to grDraw will be ignored.
