The graph section of the ‘Trace Display’ in the ‘Diagnosis’ context can be moved, zoomed and re-scaled. The changes can be made with the following mouse-keyboard combinations:
|
Adjustment |
Required action |
Behaviour |
|---|---|---|
|
Move graph |
|
The mouse pointer is displayed as a hand. The graph moves with the mouse motion. |
|
Zooming with the zoom box |
|
The zoom box will stretch from the start point to the current mouse position. Releasing the [left mouse button] will zoom the zoom box. |
|
Zooming with the mouse wheel |
|
Zooming will occur as soon as the mouse wheel is moved. |
|
Rescaling the axis |
|
The scaling follows the movements of the mouse when the [left mouse button] is pressed. |
If a graph is moved, zoomed or re-scaled with these actions, the ‘Previous View’ command can be used to return to the previous view and the next view can be opened with the ‘Next View’ command.
This history goes back to when the changes were made. The history is cleared when the view is reset to its initial state.
Double-clicking on the graph or the 
‘Reset View’ button resets all display changes.
Combining Y-axes of elements with the same unit
Signals with the same unit can be scaled together on a common Y-axis. The number of Y-axes in the graph is reduced accordingly. The reduction and combination of Y-axes can increase the clarity of the graph view.
-
Click the element name in the recording list whose Y-axis is to be combined.
The line with the element name is highlighted.
-
Press and hold the [Ctrl key].
-
Click other element names with the same unit.
The line is also highlighted.
-
Repeat the previous step until all required elements are selected.
-
Select the Combine Axes command in the context menu of a selected item.
The scales of the Y-axes of previously selected elements are combined on a single Y-axis.
Changing signal colour of an element
Signal colours can be set individually.
-
Select the ‘Change color’ command in the context menu of the element.
A dialogue box for changing the signal colour opens.
-
Select predefined colour or set custom colour by entering the RGB value or the hex value (6-digit).
The selected or defined colour is displayed as a preview in the dialogue.
-
Click the ‘Apply’ button in the dialogue.
The dialogue closes and the selected colour is imported into the graph view.
‘Add user defined channel’
You can add a custom channel to an existing recording. Custom channels enable the following:
-
View of individual bits of a recorded signal in the diagram (calculation bit mask)
-
Calculation of measurement data with formulas and graphical representation of the results in the diagram for further analyses
-
Select the ‘Add user defined channel’ command in the context menu of the recording name.
A dialogue box for adding a custom channel opens.
The dialogue provides input fields for the channel name and the unit and has a selection of calculations (e.g. bit mask). -
Enter channel name and unit and select a method from the ‘Calculation’ list.
Step 2: depending on the selected method the dialogue displays the names of the allowed recording channels.
-
Select the channel from the ‘Source channels’ list.
Step 3: the dialogue displays additional input fields depending on the selected channel.
-
Edit input fields and confirm settings with the ‘Apply’ button.
The dialogue closes and the custom channel is added to the list of elements and displayed graphically in the graph.
Adding the measuring bar
Simple measurements related to the X-axis and the Y-primary axis can be made in the graph with the measuring bar. Measuring bars can be added to the graph using the following mouse-keyboard combinations:
|
Measuring bar type |
User action |
Behaviour |
|---|---|---|
|
Measuring bar with dimensional reference to the X-axis |
Drag with [Alt] + [Shift] + [left mouse button] pressed |
The measuring bar will stretch to the entire graph height. |
|
Measuring bar with dimensional reference to the X-axis and to the Y-primary axis |
Drag with [Shift] + [left mouse button] pressed |
The measuring bar will stretch from the start point to the current mouse position. |
Measuring bar with dimensional reference to the X-axis
Symbol Delete
Measuring bar with dimensional reference to the X-axis and to the Y-primary axis
Depending on the measuring bar, the distance between the measuring bar edges is displayed with reference to the X-axis or with reference to the X-axis and Y-axis. Clicking on the ‘Delete’ symbol in the measuring bar will remove the measuring bar from the graph. If the scaling of the Y-primary axis or the X-axis is changed, all measuring bars are removed from the graph. This action cannot be undone.
Cursor with measured value display
The cursor of the graph can be activated and deactivated with the 
Show/Hide Cursor symbol in the title bar of the working section. The cursor works in the following
two modes:
|
Mode |
Description |
|---|---|
|
Line |
If the time is plotted on the X-axis, a line is shown in the graph. The position of the line is attached to the mouse cursor. At the intersection points of the line with the graph curves, information boxes are displayed with the name and the current Y-value of the signals. The time is displayed in an information box on the X-axis. |
|
Cross-hair pointer |
If time is not plotted on the X-axis, a cross-hair pointer is shown. The position of the crosshairs is attached to the mouse pointer. If the mouse cursor is over one or more data points, an information box with the corresponding Y-value and signal name is displayed at this position per data point. |
