<blockquote cite="mid:56B87251.7040903@laas.fr" type="cite">Hi
everyone, <br>
<br>
I just failed at placing an image behind a plot. <br>
I thought that would be easy: <br>
- create a figure <br>
- create an image uicontrol <br>
- create an axis <br>
- plot in the axis <br>
- set axis.filled="off" <br>
<br>
Apparently I was wrong. <br>
I did not find a way to overlap a plot with transparent
background over my image. <br>
It seems that the image is always above the plot no matter what
order the uicontrol/axes where created. <br>
I also tried to put both of them inside the same frame, but I
did not work either. <br>

You may use the z coordinate of your flat curves to manage
overlays, as in:<br>

You may then tune the scalebox factor. Actually, like with an uicontrol(style="image"), the imported image is inlaid and is not resized accordingly with the embedding graphical figure.
