P2 Explorer allows you to link to a trend via a URL. There are 2 ways of doing this:
- Sharing a link to a trend through the P2 Explorer framework.
You can link to a saved trend or a blank trend. - Creating a dynamic trend by manually entering a URL.
Security considerations
- When you share a saved trend, it will only be visible to people who have permission to view the workspace in which it is saved.
- People who do not have permission to view the included tags or attributes will not be able to view data for those tags or attributes.
Option 1. Sharing a link through Explorer
The simplest way of linking to a trend is by clicking the Share Link 
button on the Trend ribbon tab. This allows you to share the current state of a trend at any time (i.e. with the current selected options such as time range, sample interval, etc).
When a user clicks a link shared this way, the trend will either open in a tab inside the P2 Explorer framework, or as a separate tab in the browser.
When the Share Trend dialog box opens, you can simply copy and paste the URL into an email, or wherever you intend to use it.
Note: People who do not have permission to view the included tags or attributes will not be able to view data for those tags or attributes.
How the link is constructed
Saved trends are constructed differently to blank trends.
Saved Trends
When a trend is saved, it is assigned a unique number (called a GUID) that identifies the trend. The GUID is represented with a long sequence of letters and numbers. E.g. /Guid/5a594800-c01f-4f8f-a184-b390317842e6
The number after the GUID (e.g. /5) represents the current state of the trend, which is saved in the database with an incrementing ID every time this dialog box is opened.
You will notice the Frameless URL check box is automatically selected. This automatically appends ?frameless to the URL, which forces the link to open outside of the P2 Explorer framework (frameless). Frameless means that only the trend is displayed; there is no header or ribbon. If you want the URL to open within the Explorer framework, clear this check box.
Blank Trends
You can also share a trend that has not been saved - this is often called a "dynamic trend". Blank trends can be shared with anyone (tag permissions apply).
Blank trends do not have a GUID, rather they are identified by the state of the trend's variables, represented by the number after the trend (e.g. /8). This number is saved in the database with an incrementing ID every time this dialog box is opened.
Option 2. Dynamic trend via URL
You can choose to share a dynamic trend via a URL, which uses a list of variables to specify the tags on the trend and the state of the options. This allows you to link to a trend with certain options already selected, such as time range, sample interval, etc.
How the URL is constructed
The standard format of the trend URL is as follows:
[Explorer URL]/trend?[variable list]&frameless
To use a variable in the URL, add a question mark ? followed by the list of variables in the format variable name=variable value. Separate multiple variables with &.
Example:
https://perauthor01.petroleumplace.com/P2.Explorer/trend?
startTime=2014-11-01T00:00:00&endTime=2014-12-01T00:00:00
If you want the trend to be frameless, append &frameless after the list of variables.
Example:
https://perauthor01.petroleumplace.com/P2.Explorer/trend?
startTime=2014-11-01T00:00:00&endTime=2014-12-01T00:00:00&frameless

||||||||||||||||||||||||||||||||
|
selectedEntities |
The comma separated list of entities to show in the trace. Note: The URL parameters selectedEntities, templates, attributes, and attributeValues are all designed to be used together.

Format: Template name To specify a list of templates, use templates=template1,template2 etc Note: This variable was introduced in Explorer 4.4.1 |
||||||||||||||||||||||||||||||||
|
attributes |
The comma separated list of attributes to show in the trace. Note: The URL parameters selectedEntities, templates, attributes, and attributeValues are all designed to be used together.
