Interactive markers can be moved alongside the assigned base axis with a mouse click. By doing so, the interactive marker will always be positioned on the defined tick marks of the base axis: always on the tick mark that is nearest to the mouse position.

The interactive marker’s appearance can be set in the same way as for user-defined markers Marker.

Visibility

If you select this option, the interactive marker will be displayed. The visibility can also be controlled via the button in the toolbar.

General

In the General area, you can set the name and the color of the interactive marker, as well as the drawing layer and the related base axis.

Top cap / connection

The interactive marker consists of a top and a bottom cap (symbol) and a connecting line. For each element, you can select a style as well as define its size and visibility. Apart from the display styles triangle and square for the top and bottom cap, you can also select an image. You can select a image mode to display the image:

• None: the image is displayed in its original size

• Stretch: the image is adjusted in height and width to the object

• Zoom: the image is adjusted to the set size in the original size ratio

The positions of both caps can be configured independently with a fixed value or dynamically with a signal.

If the interactive marker is visible (green line in the picture above), a table will be displayed below the diagram that shows the x and y values of all curves that are defined at the marked position. The interactive marker can be moved by a mouse click. It will then jump to the tick mark that is nearest to the mouse position.
