Images on graphs [SOLVED]

Is there a way to display an image on a graph - for example, have an image inside of an annotation box? What I'm looking to do is add a plus and a minus sign to my graph to have it show the desired direction that the data should be going in. I also want there to be a tag over those images that provides more information - basically an alt text or hover help over the image.

Meghan just a little bit of searching on the forum would give you exactly what you need.

I published a dev tip on this several years ago and it's been raised as a topic several times

Thank you JG. I was able to successfully get an image into an annotation box. My next question then is: Is it possible to have a hover text on the annotation box? Any help or direction would be greatly appreciated.

Simple answer to that is unfortunately no.

There is no way to attach the equivalent of an ALT tag within WebFOCUS images.

However if you are just doing HTML output then you could use CSS to give you the hover functionality
based on a fixed area on the html page.

Here is an example
You will see reference to a file /approot/baseapp/hover.gif
This is just a 1x1 pixel transparent gif image that you will need to create.
You have to hold your graph to a location on the APP PATH (or other location that the webserver can see)
as it must be displayed in an HTMLFORM

In actual fact you can put anythng you want into the graph using the CSS map method.

The version below displays the report when hovering over the annotation, If you want to spend the time
and the number and width of the ordinal axis plot ponits is static then you could expand the method
and have a different report popup for every point, instead of using drilldowns.
(means pre generation all of the reports)

Thanks JG. Although this would probably work I think it's too much of a work around for what we are trying to do. I think we'll just stick to the image without the hover help - I don't think hard coding a static location is a usable idea for us. I do appreciate you sending the code over though and we may use this in the future.
