Function
The signal display in ibaQPanel has some extra functions compared to the usual trend graph display in ibaPDA. This document only describes the additional functions. The default functions of the display are mentioned in the ibaPDA manual.
The signal display also supports vector signals. Vector signals are specifically indicated groups. They are flagged with a 2D symbol in the signal tree.

|---|---|
 |
The desired signal group must be defined in the I/O-Manager of ibaPDA, in the category Groups. In order to display the group as vector signal in the signal tree, the option Vector has to be enabled during definition. |
If a vector signal is dragged onto a signal display, it will be shown in the 2D top view. The color scale can be based on percentage in auto scale mode or based on values in manual scale mode. The measured values do not have to be equidistant.
Moreover, the signal display supports text channels. If you drag a text channel on the signal display, the text above the curve is shown at the moment the new text signal was received. The font type of the text channels can be set in the properties of the signal display. The colors of the text channels can be displayed in the same way as the colors of the normal trend graphs.

The minimum height of a graph within the trend is 5* font size of "Axis font". |

Show signal visibility icons
Signal curves can be hidden or shown by clicking on the screen symbol before the signal legend. The display symbol changes from filled to empty. In the hidden state the curve is only masked, the signal label remains.
Disable Y-axes zoom
All operations and automatic zoom functions etc. for the Y-axis are deactivated. The user can only change the X-axis, the Y scaling remains.
Anchor markers
You can anchor the markers to the X-axis. Then the markers remain at their relative position in the trend graph and do not move while shifting or zooming.
Alternatively, the markers can also be anchored at the right/left position. Then, in pause mode, they remain at the right and left edges of the visible trend curve. This ensures that the marker table values are always displayed in relation to the selected section.
Align digital signals with legend
Digital signals will normally be shown in the lower part of the trend curve. With this selection digital signals will be shown at the height of the corresponding legend.
-
Allow text channel overlap
If this option is disabled, the overlapping of text messaged is prevented.
If messages of the text channel come in very fast succession (ms range), the text messages will be displayed in overlap nevertheless. Please note the relation between the cycle of the text channel and the update rate.
Configuration
The preferences/properties of the ibaQPanel trend graph differ from the standard trend graph in several aspects.
The trend graph, signals and Y-axis settings are the same as in the standard trend graph described in the ibaPDA manual.
