Navigating the plot

Auto-follow, zoom, pan, cursor and the plot context menu.

3 minute read

Most navigation is done with the mouse directly on the plot; the View panel holds the toggles.

View panel

Row	Control	Function
Auto-follow	switch	Keep the newest data in view (on by default)
Zoom	▣	Zoom to area — drag a rectangle; click again to return to scroll zoom
	↺	Reset zoom
Display	cursor	Show the measurement cursor (on by default)
	grid	Show grid lines
	⏸	Pause the plot

Mouse and keyboard gestures

The plot itself understands these gestures — the same list is available in the plot as a small Plot controls card:

Gesture	Effect
Scroll	Zoom in and out around the pointer
Shift + scroll / drag	Zoom or pan the X axis only
Ctrl / Cmd + scroll / drag	Zoom or pan the Y axis only
Alt + scroll / drag	Zoom or pan both axes
Middle-drag	Pan
Drag an axis	Pan that axis alone
Right-click	Plot context menu

While a modifier key is held, the plot switches to panning and shows a badge naming the active axis; releasing the key returns to the previous mode.

The card can be dragged anywhere over the plot and closed with its ×. Bring it back from the context menu (Show plot controls); the choice is remembered.

Auto-follow

With auto-follow on, the X axis scrolls to keep the latest samples visible — the normal mode during live acquisition. Any zoom or pan that leaves the incoming data behind switches it off automatically.

Re-enable it with the Auto-follow switch, the Home key, or Ctrl+A.

Zooming

Scroll zoom (default) zooms around the pointer. For a precise window, click the Zoom to area button and drag a rectangle:

Reset zoom (toolbar ↺, Ctrl+Z, or Reset view in the context menu) returns to the default window; Reset view additionally re-enables auto-follow.

Cursor

The cursor follows the pointer across the plot, marks where it crosses every visible trace, and labels each crossing with that trace’s Y value in the trace colour. The X position is shown at the bottom of the cursor line.

Pausing

Pause (⏸ or Ctrl+P) freezes the plot while data keeps streaming in the background — useful for reading a moment that just went by. Press it again to resume.

Item	Action
Reset view	Reset the zoom and re-enable auto-follow
Zoom to area / Zoom to mouse	Switch zoom mode (only the inactive one is listed)
Refresh	Clear the buffered points of all traces and start drawing fresh
Show / Hide plot controls	Toggle the gesture card
