Graphics

00:00 ⟶ 00:04

In this video, we'll cover the core features of graphic displays in Nexus.

00:04 ⟶ 00:08

Graphics in Nexus have a unique relationship to PARCview.

00:08 ⟶ 00:17

When a graphic is opened in Nexus, an instance of PARCview is created in the background that 

renders images of the display and sends them to the Nexus front-end.

00:18 ⟶ 00:25

This means that graphics must initially be created and configured in PARCview, but can be interacted with in Nexus.

00:26 ⟶ 00:31

Note that any changes made to the display in Nexus will not be saved to the graphic file.

00:31 ⟶ 00:38

All settings established in PARCview will be present in the Nexus graphic, including the update rate and custom scripting.

00:39 ⟶ 00:45

However, the update rate of Nexus graphics can be customized to adjust responsiveness and CPU usage.

00:46 ⟶ 00:52

Zooming can be performed by holding down Control and scrolling the mouse wheel or pressing the plus and minus keys.

00:53 ⟶ 00:58

Scrolling the mouse wheel without holding down Control will pan the display up or down.

00:58 ⟶ 01:03

Tags can be added to trend elements by dragging and dropping from Tag Browser.

01:04 ⟶ 01:10

The options menus for the trend display and tags can be launched by right-clicking on the element's plot area and Tag Info Grid.

01:11 ⟶ 01:16

An element that is bound to a tag will display a question mark when hovered over.

01:16 ⟶ 01:21

Right-clicking the bound element allows users to open Tag Info and trend the tag.

01:22 ⟶ 01:25

Double-clicking the bound element will also trend the tag.

01:25 ⟶ 01:35

Nexus can also be configured to pass the tag to an external application when an element is double clicked, 

replacing the default behavior of launching a new trend.

01:36 ⟶ 01:42

A bounded tag can be added to embedded or non-embedded displays by dragging and dropping from the element.

01:43 ⟶ 01:48

The File menu can be used to copy an image of the graphic to clipboard or to a new browser window.

01:48 ⟶ 02:01

Finally, as with all other Nexus displays, graphics have a unique URL linking directly to the display that can be bookmarked, 

shared with other users, or used to embed the graphic in a website via iframes.
