The ScatterGraph sample describes how you can use Microsoft® Direct3D® for graphic visualization. It uses the RenderToSurface features of the Microsoft® Direct3DX framework to render text and bitmaps dynamically.

Right-click the sample's interface to display a shortcut menu. The following table list the available menu commands.
| Command | Action |
|---|---|
| Load Data From File | Loads new data from a .csv (comma-delimited) file. A .csv file can be exported from Microsoft Excel or any spreadsheet program. |
| Reset Orientation | Resets the viewpoint to a known state. |
| Show Connecting Lines | Connects the data points if the order of the data is important. |
| Show Height Lines | Makes it easier to see the y-value in comparison to the other values. |
| Show Foot Lines | Makes it easier to see the x-z relationship. |
| Show Base Plane | Shows the plane where y=0. |
| Auto Rotate | Turns rotation on and off. |
The file must be formatted so that the first row and columns are headers that title the data. A header can contain the tag TEXTURE:filename.bmp to indicate that it contains a picture. The rest of the data must be numeric. See Bargraphdata.csv in (SDK root)\Samples\Multimedia\VBSamples\Media for an example.
Holding the mouse button and dragging rotates the graph.
