How to combine Vision Acquisition & XYgraph

[MartinO.]

Hi everybody,

I would like to know if it is possible to combine a real-time acquisition with a XY graph. Actually I have a XY graph with a plot and I would like to put the camera acquisition in the background for instance, but my main goal is to have a mark on my camera acquisition's panel with the same scale than the XY graph. Any Idea ?!
Is it possible ? and if it's not, is there any other solution ?

Best Regards,
MartinO.

Martin,

You could probably make the XY graph with a transparent background and put an image display underneath, but it would be difficult to match the scales.

I would recommend using the overlay functions to draw lines and points directly on the image display.  This way there is no rescaling required.  It is pretty easy to do.  One trick is to use overlay bitmap to draw small icons (cross, plus, dot, etc.) on the image.  These show up better than a single pixel point.  Just remember to offset the XY coordinates to align the icon properly.
