Is there any way to add an item/control that can be used within Visualization Studio?  In particular, I was thinking scrolling text would be a useful item to add.

I'm not sure I understood the q, so this may be missing the point. The text element in visi studio will do scrolling text, Barratts visis play with text a lot. Just put the necessary math expression in the location equation.

Maybe thats not what you meant though.

Is there doco somewhere on the math expressions?

I can't find any documentation of how to set the various settings in vis studio to control images ad text etc.

I guess I just don't know where to look!

Thanks for the suggestion.  I needed "in-place" text scrolling which may be possible with math expressions but it sure would be nice to have some documentation of this stuff...

Hi again

I dont come here that often. Cant find my scrolling text stuff... too many visis!

The default text location equation looks something like:
x1=0;y1=.4;x2=1;y2=.6
where x1,x2,y1,y2 control the outer boundaries of the text area.
All you need do is add some maths so those numbers steadily change. Eg y2=t;t=t+.01 or similar

Maybe later add maths to deal with limits to keep it on screen.

Check out barrett-word-text2.mjv for a demo.

Note x1,x2,y1,y2 are interdependant with other variables eg font size, so change everything just a little at a time, else its liable to go off screen leaving you with no info where its gone. Theres no error report, trace, or variable print.
