RE: Random order in chart

I don't have time to map this out in any detail, but I would use <counter> elements chained together with the 'current' function to encode the possible combinations of screen positions. This thread contains some more hints on this approach: http://www.millisecond.com/forums/Topic2148.aspx.

Good luck!

BTW, the 'current' option in '/select' might also be useful in the number to letter mapping (1->A, 2->B)...

Random order in chart

Hi all,
I need to design experiment that has one quite complicated part...

Imagine a chart which has 3 categories horizontaly, and 2 verticaly.
It gives 6 places where you could put some informations (Graph 1)

Graph 1 :)

X | Y | Z
$| 1 | 2 | 3
&| A | B | C
----------------

In the chart there are text informations and they can be coded as a text stimuli as well as image - doesn't metter.

All information are definied (1,2,3 and A,B,C).
Conections between numbers and letters are definied as well.

If 1 then A
If 2 then B
If 3 then C

I need to have those 3 boxes (horizontaly - X,Y,Z) randomly asign to information for each participant.

In other words I'm looking for way to design random order for location for each number inside those 3 boxes, and way to define from start connection between numbers and letters in those boxes.

How to do it?

I have script where I have a static information, but I'm not sure where to start coding with this random order.

Need to say one more thing.
Each information is hidden under a red box during the experiment.
Participants can use the mouse to see what's under those red boxes, however he can see only one information at once.
