Y axis parameters

Previous chapterNext chapter Show allShow all    Hide allHide all

In this dialog and in the dialog Curve parameters the curve parameters are defined.

Configurable options are:

Axis type

Defining of the scaling of the Y-axis

- Linear

Linear division of the Y-axis

- Logarithmic

Logarithmic division of the Y-axis


Position of the Y-axis in the diagram. (0 = Left, 100 = Right)


Define representation range of the process variables within their configured technical limits. (Zoom function)

Axis subdivision

Definition of the axis subdivision

- Main subdivision

Number of main subdivisions with value indication

- Lower subdivision

Number of subdivisions between two main subdivisions

- Tick length

Length of the main subdivision lines (pixel)

Grid lines

Representation of help lines on the main subdivisions


Automatic setting of scaling and axis subdivision in online operation.


Position of the axis labelling




Defining of the axis colour (CAUTION: Can be configured independently of the trend curve colour)

After the configuring of the trend curves and the associated Y-axis parameters, the new trend curve is accepted into the diagram by pressing the "OK" button. It is displayed in the diagram as an available trend curve (trend curve name, process variable name).

For each trend curve the corresponding type of processing (active, with Y-axis) has then to be laid down. The configuring is done by marking the trend curve in the window and setting the appropriate option.
