I have a sensor data whose value varies from 0 to 65536 as the data type is uint16. I want to draw a 2D plot which should vary from -3000 to +3000 on X-axis with respect to time.
For example if in my data set I get
0 equivalent to -3000
32768 equivalent to 0
65536 equivalent to 3000
Please kindly excuse if the question is very trivial as I am beginner to MATLAB.
Thanks

If your data is uint16 then it varies from 0 to 65535.

your_data = uint16(randi(65536,1000,1)-1);
scaled_data = -3000 + round(6000 .* (double(your_data) ./ 65536));
Please accept an answer if it helps you.
