Picture type Extended trend

The picture type Extended trend is used for displaying line graphics from online and archive values. (You will find more information on the pre-defined picture types in the chapter 'Pictures / Pre-defined picture types'.)

In contrast to the dynamic element trend graph it is possible to zoom, browse, query and scale online values (HD storage) and values from archives. The software module must have been licensed to use the function. The creation of the extended trend picture is done by selecting the respective picture type. You will find information about creating such a picture in the chapter Overview picture types.

On opening the picture an empty picture is opened and the menu Control elements in the menu bar is filled.

With the help of the control elements you can arrange the individual online operating elements in the picture (overall display; in the editor there is only a two-dimensional display). The function elements differ from one another by buttons (for on-line operation) and views (display of necessary display sums).

By selecting the entry Default in the menu Control elements all control elements are loaded with standard values at predefined positions.

`Default`	Automatically insert default elements If not all the control elements are needed, they can be removed one by one lateron. The elements can be moved and individually arranged.

Changes to the control elements in respect of size, orientation and arrangement are possible. Elements which are not needed in the on-line display or must not be present can be deleted from the picture (e.g. play, stop, refresh, etc.). The addition of other dynamic and static picture elements is also possible.

The activation of the picture with the extended trend function in on-line operation occurs via the use of the function "Picture switch".
