EvGrid methods

Description

SetDepthRangeGrid

SetDepthRangeGrid(EDepthRangeGridMode GridMode, double Separation)

Summary

Set the grid mode and separation of the depth/range grid lines.

Parameters

GridMode
Specify the depth/range/reference-line mode of the depth/range grid. Use an enum for EDepthRangeGridMode.
Separation
The distance between depth/range grid lines.

Return

None.

Example

option explicit
Dim vEchoviewCom: Set vEchoviewCom = CreateObject("EchoviewCom.EvApplication")
 
Dim vEvFile: Set vEvFile = vEchoviewCom.OpenFile("C:\Myriax\Echoview\Echoview5\Test.EV")
Dim vEvVariablesCollection: Set vEvVariablesCollection = vEvFile.Variables
Dim vEvVariable: Set vEvVariable = vEvVariablesCollection.FindByName("Sv V1 telegrams T1")
 
Dim vlineCollection: Set vlineCollection = vEvFile.Lines
Dim EvLine: Set EvLine = vlineCollection.FindByName("Line2")
 
vEvVariable.Properties.Grid.SetDepthRangeGrid 2, 20.0 
' eReferenceLine = 2
 
vEvVariable.Properties.Grid.DepthRangeReferenceLine = EvLine
MsgBox "LINE is " + vEvVariable.Properties.Grid.DepthRangeReferenceLine.Name

Note: Test.EV is an EV file that contains a line called Line 2. The snippet uses Line 2 as a reference-line for the deph/range grid.

SetTimeDistanceGrid

SetTimeDistanceGrid(ETimeDistanceGridMode GridMode, double Separation)

Summary

Set the grid mode and separation of the time/distance grid lines.

Parameters

GridMode
Specify the time/distance mode of the grid to be used. Use an enum for ETimeDistanceGridMode.
Separation
The distance between time/distance grid lines.

Return

None.
