Hello, by using the the "axes" and "imshow" command, it is possible to place a picture at a specified position in an existing figure / plot using. For example, see question + answer

How to place an image over existing plot.

However, the coordinates used by the "axes" command refer to the entire figure window. In my case, I want the picture displayed at positions which refer to the x / y axes of the main plot, i.e. (0, 0) shall not be the lower left corner of the figure, but the origin of xy coordinates of the plot.

Background: I am trying to built a work-around for a previous inquiry lnk Multiple (rotated) histograms in one xy plot. I have created multiple pictures (= identically scaled and rotated histograms), now I want show them "stacked": Their baseline should be at specified x coordinates of the xy-plot (e.g. x=1, x=2, x=3)

Thanks in advance for any input, Dan

It's possible. You just need to convert the axes1 position to figure position. Fairly easy to do this from scratch, but I recall seeing a FEX function for this... I'll see if I can find it

EDIT: this is the one I was thinking about

To insert an image does not require an overlaid axes. You can do it as in this example:

That said, using an overlaid axes might be desirable if you wanted the inserted histograms to actually be histogram objects instead of static screenshots.
