I've tried to display an image in the XRT/graph data area background as described on Pages 91-93 of the XRT/graph Programmer's Guide and Reference Manual.
However, I don't see anything displayed. How can I resolve this?
Ensure that you have data attached to the XRT/graph widget. If there is no data defined, no data area will be drawn, and therefore no data area background image will be drawn.
If you have data, but you are trying to use an image other than an XPM, XWD, or GIF image as the background, ensure that you are following the steps on Pages 144-5 of the XRT/graph Programmer's Guide and Reference Manual to register new image types (JPG and PNG support is offered).
