Help formatting data into 3d surface

[8bitbanger]

Hi Folks,

I'm struggling trying to display some data in a 3d plot. I'v studdied the example here but am getting no where! http://forums.ni.com/ni/board/message?board.id=170&message.id=433150&query.id=1242328#M433150

Basically the data I'm interested in viewing is a 2d array. Each row in the record represents a size bin (52 total rows). Each of these rows is divided into discrete scatter angle bins (16 total columns). SO, each element represent a relative light intensity, at a discrete angle, at a particlar size.

I don't understand how a 2d dataset gets correlated into X,Y,and Z matrix formats.

Any pointers?

Regards,

Jamie

Go to that thread you linked and then open the link to thread with the car example. It is a very simple example that you can poke at. Play with that example and get familiar with what values do what. If you still have trouble massaging the data into a shape/form that serves your needs, post back.

Trying to help,

Thanks for the reply. I did have a look at that example, but unfortunately it isn't of much help. I'll continue to mess with it, but it easily obscures (I think) the principals of data formatting requirements for 3d plot by an overwhelming amount of data points. ie I have no idea what point is what on that plot, where it should be....etc

I honestly don't know what expect with my dataset - I basically just want to visualize several 1d arrays over 'time' ('time' being the bin sizes). I thought there would some sort of easier way to go about this, but the 3dplot is all I could find.

Cheers,

Jamie

100 data points in a 3d graph is small.

I suggest you change one of the values and re-run it to see which point you changed. Repeat with other points until you figure it out.

If 100 points is too many, empty the array and put your own data in to start.

Still trying to help and not giving up,
