04 Plots and Cursors

The plot area contains three elements: an axis, the configured plots and cursors. Cursors are part of a view, like plots and folders, but they are not visible in the view configuration hierarchy. So, if you change the view, you also change to a different set of cursors.

Views

A view combines a freely configurable set of plots organized in the form of a tree. Users can define multiple views and choose between them at any time to get the information they need.

Plots

Plots are easily configurable specific representations of signal data. Plots may have a common zoomable and scrollable axis (e.g. the time of the trace) or they may be adjusted into the window size (charts).

Cursors

Cursors allow navigation and measurement within signals.
Users can specify any number of cursors. A dedicated details area shows the current position and delta distances.

H210 View - How to add a cursor

Initially, one cursor is part of a new view.

To add more, press the "Add new Cursor" button in the toolbar or use the context menu of the Axis or Cursor Details.
Change color and/or name in the opened dialogue.
To get rid of a cursor, use the context menu of the cursor (right click on the grip), or the context menu of the axis to delete all cursors.

H211 View - How to switch between cursors

If you have more than one cursor, you may need to switch between them. You can activate a cursor or simply make the cursor visible (by changing the axis position).

In the context menu of a cursor, you find the commands:Activate previous/next/Cursor 0--3 to activate another cursor and make it visible (go to its location)
and Show active/Cursor 0--3 to only make a cursor visible (go to its location).
Single-click the cursors in Cursor Details to activate the cursor;
Double-click the cursors in Cursor Details to aktivate and make the cursor visible (go to its location).
It is even easier to use the keyboard shortcuts (see 18 Keyboard Shortcuts).

H212 View - How to move in time (or other domain)

You can move the the axis and cursor by:

Use the horizontal scrollbar.
Left click on the axis and move.
Use the mouse wheel plus the SHIFT key.
Left click on the wave area and move (this moves the active cursor).

H213 View - How to make a domain range visible

You can make a given range in time (or frequency,..) visible by:

To zoom in/out relative to the active cursor, use the buttons in the toolbar or use the keyboard (+,-).
To zoom in/out relative to the mouse, use the mouse wheel plus the CONTROL key.
To zoom fit, use the Zoom fit command in the toolbar.
Left click on the wave area (with the CONTROL key) and select the area that you want to zoom in or out. Release the mouse to zoom in/out.

Adding, Activating and Deleting Cursors

Initially, one cursor is part of a new view. To add more, press the "Add new Cursor" button in the toolbar or use the context menu of the Axis or Cursor Details. To make a cursor active, you need to press the grip of the cursor in the cursor track of the axis, or you select the cursor in the Cursor Details field. To get rid of a cursor, use the context menu of the cursor (right click on the grip), or the context menu of the axis to delete all cursors.

Switching between cursors

If you have more than one cursor, you may need to switch between them. You can activate a cursor or simply make the cursor visible (by changing the axis position).

In the context menu of a cursor, you find the commands:

Activate previous/next/Cursor 0--3 to activate another cursor and make it visible (go to its location)
Show active/Cursor 0--3 to only make a cursor visible (go to its location).

Instead of using the context menu, you can click on the cursors in Cursor Details :

Single-click to activate the cursor;
Double-click to aktivate and make the cursor visible (go to its location).

It is even easier to use the keyboard shortcuts (see 18 Keyboard Shortcuts).

Moving in time (or frequency,...)

Use the horizontal scrollbar.
Left click on the axis and move.
Use the mouse wheel plus the SHIFT key.
Left click on the wave area and move (this moves the active cursor).

If you move the cursor outside of the plot area, the axis will change to keep the cursors visible. Coloured arrows on both sides show you the speed modes (depending on the mouse’s position relative to the plot area).

Zoom in/out or fit

To zoom in/out relative to the active cursor, use the buttons in the toolbar or use the keyboard (+,-).
To zoom in/out relative to the mouse, use the mouse wheel plus the CONTROL key.
To zoom fit, use the Zoom fit command in the toolbar.
Left click on the wave area (with the CONTROL key) and select the area that you want to zoom in or out. Release the mouse to zoom in/out.

Move to next/previous event

Select the signals (which may be multiple) that you want to iterate. Press Goto Previous/Next Event in the toolbar or use the keyboard shortcuts (see A02 Keyboard Shortcuts).

Moving up/down the signals - expand/collapse folders

To scroll in vertical area, just use the scrollbars, the mouse wheel (without CONTROL keys) or the keyboard (UP, DOWN, PAGE_UP, PAGE_DOWN, POS1, END) as you would do in another editor. Use the SPACE key to expand or collapse folders, or use the tree control.
