Data Browser Plot Window

The Plot window could be considered the "main" window of the Data Browser. Its title bar displays the name of the associated configuration file, or "<not saved>" for a newly created Data Browser instance that is not (yet) saved to a configuration file. plot

Plot Window Button Bar

The button bar on top of the plot window provides interactive pan and zoom operations. In case the button bar is not visible, use the plot's context menu to re-enable it.

Selecting a Y Axis

If a plot has multiple Y-Axes, most of the Zoom and Pan operations described above can operate on all axes or only a selected Y-Axis. To select a Y-Axis, simply click onto the Y Axis. The axis will redraw in a slightly wider line width, and grid lines in the plot further emphasize the selected axis.

To de-select a Y-Axis, click on the X-Axis or just outside the actual plot region and Y-axes area.

'Rubberband' Zoom

You can zoom into the plot by 'rubberbanding' a rectangle: Click at start point, drag rectangle, release, and the plot will zoom into the selected region.

Sample Markers

When clicking into the plot window, a marker is placed next to the nearest sample, displaying the channel name, value and other information about the sample. You can place multiple markers.

To remove markers, use the plot's context menu.

'Drop' PVs

You can use Drag-and-Drop to add PVs to the plot by dropping PVs into the plot region itself, or onto a Y-Axis. When dropping onto the Plot, the new PV is added with its own new Y-Axis. When dropping onto an existing Y-Axis, the PV is added to that Y-Axis.
