The range plot element of the 1D Plot view can display up to three different range plots:
Binned range: Plots the average range over all pixels that are determined by the Pixel Binning Algorithm. This value

represents the current range in meters.
Smoothed binned range: Plots a time-based moving average of the binned range. To adjust the algorithm of the time-

based moving average, go to the 1D Plot Options view inside the Options tab. A greater SMA data buffer size might
result in a slower moving visualization.

Choose between two different algorithms to calculate of the averaged measurement results:
– Simple moving average (SMA): The mean calculated from the previous N data without any weighting. The SMA data
buffer size defines the magnitude used for SMA calculations.
– Exponentially weighted moving average (EMA): A type of infinite impulse response filter that applies exponentially
decreasing weighting factors. The weighting for each older datum decreases exponentially but never reaches zero.
EMA weight implies the quantifier used for the calculation of the EMA. Lower values result in less weighting of past
measurement outcomes and thus longer averaging times.
Sigma of binned range: The blue cloud determines the current time based on moving the standard deviation of the

sensor signal; inside the 1D Plot Options view, choose a deviation width of 1 sigma or 3 sigma.
