How can I map a 1D data set (line) into a 2D image (grid)?

[shotskie]

I am relatively new to LabView still, and would appreciate any advice or guidance.

In my measurement system, data is taken as a function of distance only (time also, but I can worry about that later).  The result is an intensity measurement as a function of distance, I(z).  In reality, my 1D line is not straight, it is laid out in the shape of a grid, which I know the specific dimensions of.  I would like to create an image that shows intensity in the shape of this grid, I(x,y).

My first effort was starting with a blank image, and assigning rows/columns of pixels a color (temperature) according to the measured value.  But I have had little luck with this so far.

Can anyone offer some advice as to how I can create such a 2D image?  How can I map a line into some arbitrary grid shape? 

Thanks,

Aaron

How is the 1D array laid out in 2D? Can you attach a typical example.

(Sometimes all you need is to reshape the 1D array into 2D, then wire it to an intensity graph. Any other mapping require a bit more code, but probably won't be difficult either).

I have attached an image to better illustrate my situation.

I start with a 2D array of Space and Time.  At any one moment in time, I have a 1D array of Intensity as a function of Distance.  This 1D array I would like to map to some 2D space, a function of (x,y) rather than just length.  This is because, during experiments my 'line' is laid out in some grid pattern.  Suppose I am using a series of temperature sensors attached to a rope, and this rope is laid out into a grid along one plane.  I would like to know the temperature across the plane.

I would like to do this at every point in time, to create a map of temperature across the grid as a function of time.

In the image, I call out points Zl and Zm to call out that I know how the indices of my 1D space array correlate to actual positions in real space.  I am not sure how to recreate such an image, though, in LabView.

Initialize an 2D array with all zeroes and keep in in a shift register. using "replace array subset", replace elements according to the scaled 2D indices (x,y) with the current temperature (z) value. See how far you get....

The 2D array worked great!  Thank you for pointing me in the right direction.
