As of version 3.0 of the ARTeMIS Modal software, the Processed Data Window support defining the Mode Markers manually.

A special feature that is presented across data set boundaries in all 2-dimensional displays, having a frequency abscissa, is the so called Mode Marker Lines. The lines are used to indicate where you believe that modes are present in the frequency domain.

The reason for this feature is that all modes almost never reveal themselves clearly in a single display. A specific transducer might be placed in a node of a mode which will make it impossible to see the mode in the corresponding auto-spectral density display. A reference might also have difficulties in seeing a specific mode for a specific data set, whereas it is very easy in another data set. It can therefore be difficult to have a clear picture of how many modes are present in the data. This is the reason for using the Mode Marker Lines that are global to the project.

Creating a Mode Marker Line

The only places the lines can be added and edited is in the Processed Data window.

Put the cursor at the frequency where you believe there is a mode as shown below:

When you have placed the cursor right-click on the mouse to activate the context menu. Select the menu item Mode Markers, New:

The Mode Marker Line is now created and look as shown below:

You can now move the cursor to another position and create more Mode Marker Lines as shown below:

The Mode Marker Lines will now be shown in all 2D-displays having a frequency abscissa.

Editing the position of a Mode Marker Line

To edit the position a Mode Marker Line move the mouse close to Mode Marker Line you want to edit. When you get close enough the color and style of the line will change as shown below:

While the line is highlighted right-click on the mouse to activate the context menu. Select the menu item Mode Markers, Edit:

The display is now put in an edit mode. If you click somewhere on the display with the mouse the Mode Marker Line will move to the frequency position closest to the point. You can also keep the left mouse button pressed and drag the Mode Marker Line to the desired position. To stop editing the position, click on the desired position and it will stop the edition mode. You do not have to select the Mode Marker Line to perform this operation.

Delete a Mode Marker Line

To delete a single Mode Marker Line move the mouse close to Mode Marker Line you want to delete. When you get close enough the color and style of the line will change as shown below:

While the line is highlighted right-click on the mouse to activate the context menu. Select the menu item Mode Markers, Delete:

This operation will remove the Mode Marker Line from all displays where it is shown.

Delete all Mode Marker Lines

To delete all Mode Marker Lines right-click on the mouse to activate the context menu. Select the menu item Mode Markers, Delete All:
