To access bitmaps programmatically and assign them to the graph
background, you can use the following steps:
Insert a bitmap resource into your Visual C++ project. Import an
existing bitmap or create a new one. This example will assume the
default resource ID for the bitmap is IDB_BITMAP1.
The CWGraph Object has three Images, indexed as follows: 1)Caption 2)
Graph Frame 3)Plot Area. This example uses index 3 since we want to
assign a new bitmap to the plot area of the graph.
In a simple example, you can add the following code to the event
handler for a button on the dialog. The SetPicture property takes an
IPictureDispatch. Use a CPictureHolder instance to create and return a
reference to the bitmap, then assign this to the Plot Area Imag
e:
CPictureHolder cph;
cph.CreateFromBitmap(IDB_BITMAP1);
m_graph.Images(COleVariant(3.0)).SetPicture(cph.GetPictureDispatch());
This will load the bitmap into the plot area of the graph.
