echo rank on the [Red], [Green] and

• Method 2:
1) Select [31] on the [Rank].
2) Set the RGB values for 31 echo

3) Interpolate the RGB values be-
tween the maximum rank and minimum rank on the [Fitting To Curve] with the fol-
lowing curves (setting range: -20 to 20).
Setting range > 0: Logarithmic curve, useful to emphasize the weak echoes.
Setting range = 0: Straight line
