How to view OBIEE dashboards / Reports / Charts in IPAD?

The correct answer to this question is that you need to modify the default chart rendering type in OBI to PNG.

This will allow the rendered graph images to by pass the default rendering and display an image that is visible in the Safari browser as intended.

Please mark this as the correct answer as here is how to do this. You can find this in the OBI 10g Presentation Services admin guide documentation, http://download.oracle.com/docs/cd/E10415_01/doc/bi.1013/b31766.pdf

Oracle BI Presentation Services uses a third-party charting engine to render charts (PopChart Image
Server from CORDA Technologies, Inc.). You can override the default image type by modifying the
Oracle BI Presentation Services configuration file (instanceconfig.xml)

You need to create the elements <Charts> and </Charts> after the <ServerInstance> element, and
place your entries between the <Charts> and </Charts> elements.

Specifying the Oracle Business Intelligence Chart Image Type
You can override the image type generated by the PopChart Image Server. The internal default is
Flash.
The other choices are SVG (W3C Scalable Vector Graphics), PNG (W3C Portable Network Graphics),
and JPEG. Flash and SVG images provide the greatest degree of interaction because they support
mouseover behaviors (such as pop-up data labels), navigation, and drilling.

The following entry is an example:
<Charts>
<DefaultImageType>PNG</DefaultImageType>
</Charts>

Of course restart presentation services service and possibly boot the entire server if you are feeling saucy!
