Selecting the horizontal scale in the echograms
The horizontal scale controls how "fast" the echograms move from right towards left across the ME70 presentation. You can change the horizontal scale on the Horizontal Axis page in the Echogram dialog box.
Context
The echogram travels from right towards left across the ME70 presentation. On the Horizontal Axis page you can choose the horizontal scale of the echogram. This controls the "speed" of the echogram.
•  Distance: The horizontal scale is based on sailed distance. Select resolution and unit.
•  Time: The horizontal scale is based on time. Select resolution and unit.
•  Ping: The horizontal scale is based on the number of transmissions (“pings”) made. Select View Size to specify that the number of horizontal pixels shall define the number of displayed horizontal pings using one ping per pixel.
•  Speed: The horizontal scale is based on the relative speed you choose. Select speed with the ruler.
