How do I create a persistent bitmap in the XY graph's "PlotImages" property?

[DSV4_Seacliff]

I have found that overlaying 2D picture drawing elements such as lines, circles, and text is very useful, but the images drawn are not persistent (i.e. they disappear if another window is moved in front of the graph).  In Visual Basic 6.0, there is a property for pictureboxes called 'AutoRedraw" that allows drawing to a persistent bitmap that automatically redraws the graphics if the user moves other windows in front of the picturebox.  Is there a parallel feature in Labview 2009?  Another way to do this, perhaps?

Hello,

Is it possible to have you post your VI or screen shot of your VI to demonstrate your issue?

Thanks!

Thanks to both of you for replying.  Embarassed to say that I had a bug that was erasing the plotted images when i moved the mouse over the graph under certain circumstances - appeared like what I described, but it was not actually happening.  The drawn images are indeed persistent by default.  Which begs the question as to whether they can be drawn without the underlying persistent bitmap as is possible in VB6.  The only time I do it there is for speed . . .
