how to get the image using imshow for variable voltages

1 view (last 30 days)
I have used NI-6255 for extracting the variable voltages from the thermal sensor array of pixels by addressing each pixel
I want to get an image in gray-scale(imshow) based on the change in voltage i.e. for higher voltage brighter spot and low voltage darker spot.
sensor array pixels: 32x32 address lines :10

Sir,
code i wrote was
(after initializing )
start (ai);
data=getdata(ai);
imshow(data);
the window displayed is not showing any image corresponding to the voltage values fed, instead i get a single vertical line .

Is ai configured for multiple channels? If it is not then the getdata(ai) is going to return a vector rather than an array, and you will need to reorder or reshape() the vector to become a data array that you can imshow()
