You can generate a WBMP PopChart image using the @_WBMP server command. For example, the following HTTP request will generate a WBMP PopChart image:
http://localhost:2001/?@_FILEexamples/apfiles/bar.pcxml@_WBMP
You can embed a WBMP image in WML simply by making it the source of an image tag. For example, the following image tag embeds the WBMP image we created with the HTTP request above. It also provides a description of the image (My PopChart) in case the browser cannot display images.
<img src="http://localhost:2001/?@_FILEexamples/apfiles/bar.pcxml@_WBMP" alt="My PopChart" />
