<\/p>\n

This article applies to version 4.3.1 of P2 Explorer.<\/p>\n

Overview<\/span><\/h3>\n

A trend displays time-series data, such as tags and attributes, as a line chart over a selected period of time.<\/p>\n

To create a trend, you need to open a new blank trend and then add tag or attribute data to this. The screenshot below shows a new trend, with two attributes:<\/p>\n

\"\"<\/a>

Trend Overview<\/p><\/div>\n\n\n\n\n\n
Trend Ribbon Tab<\/strong><\/td>\nUse the buttons on this tab to refresh, save, or share the trend. (Refresh, Save, Snapshot, Share Link, Print, Export CSV<\/em>)<\/td>\n<\/tr>\n
Selectors<\/strong><\/td>\nThe selections you make affect the time range of the chart, as well as how P2 Server fetches the data<\/a>, and how the trace line is displayed.<\/td>\n<\/tr>\n
\u00a0<\/td>\n\n\n\n\n\n\n\n\n\n\n
Time Range<\/em>:<\/td>\nThis defines the start and end date and time of your trend.<\/td>\n<\/tr>\n
Sample Method<\/em>:<\/td>\nThis is the method (for example, average) that P2 Server uses to collect your trend data.<\/td>\n<\/tr>\n
Sample Interval<\/em>:<\/td>\nThis is the interval (for example, 1 week) that P2 Server uses to collect your trend data.<\/td>\n<\/tr>\n
Y Scale Type<\/em>:<\/td>\nYou can choose Log (uses logarithmic data points) or Linear (uses actual data points).<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/td>\n<\/tr>\n
Trace<\/strong><\/td>\nThe trace displays time-series data, such as tags, over a period of time (Time Range)<\/em>.<\/td>\n<\/tr>\n
Range Selector<\/strong><\/td>\nThe highlighted section in the range selector matches the start and end of the trend time range<\/em>. Use the range selector as a longer trend, to help identify highs and lows. You can select smaller periods within the range selector, to pick a new time range<\/em>.<\/td>\n<\/tr>\n
Tags List<\/strong><\/td>\nDrag and drop tags, attributes or attribute values into this list to include them in the trace. Each one is assigned a legend colour.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Tutorial<\/span><\/h3>\n

In this tutorial we\u2019ll add a new trend, and then drop some attributes into the Tags List, to create a trace. We'll then experiment with features of the resulting trend.<\/span><\/p>\n

\"\"<\/a><\/p>\n

Let's go through this process, step-by-step.<\/p>\n

\n

Step by Step: Adding a New Trend<\/h3>\n

First we'll open a new trend and put some data on there. Next, we'll experiment with changing selections and using the range selector, and then we'll add a hairline with comments. Next, we'll save the trend. And finally, we'll locate and open the saved trend.<\/p>\n

If you have access to the training environment, you can follow the steps exactly as outlined here. Otherwise, you will need to adjust the configuration to suit your data.<\/p>\n

Step 1. Adding a New Trend<\/h4>\n

Open the Home<\/strong> tab on the Explorer ribbon, and click New Trend<\/strong>.<\/p>\n

\"\"<\/a>

Click New Trend<\/p><\/div>\n

A new Blank Trend<\/em> opens in Explorer, with the following defaults:<\/p>\n\n\n\n\n\n\n
Time Range<\/em>:<\/td>\nFrom<\/strong> 1 week To<\/strong> {current date and time}<\/td>\n<\/tr>\n
Sample Method<\/em>:<\/td>\nAverage<\/td>\n<\/tr>\n
Sample Interval<\/em>:<\/td>\n1 day<\/td>\n<\/tr>\n
Y Scale Type<\/em>:<\/td>\nLinear<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
\"\"<\/a>

New Blank Trend with Selector Defaults<\/p><\/div>\n

Note that the Page<\/strong> tab on the ribbon is replaced by the Trend<\/strong> tab.<\/p>\n

Step 2. Adding an Attribute or Tag to the Trace<\/h4>\n

Related: Searching for Tags and Hierarchy Attributes<\/a><\/p>\n

To add attributes or tags to the trace, you need to drop them into the Tags List<\/em>, or manually type in the names, if known. You can also add calculations to items in the tags list.<\/p>\n

Dropping an Attribute into the Tags List<\/em><\/strong><\/p>\n

To add an attribute to the Tags List<\/em>: Open the hierarchy navigator, select a hierarchy, then search for the attribute you want to trace and drag it into the tag list. Follow the steps below:<\/p>\n

1. Click the View<\/strong> tab on the Ribbon, then click Hierarchy<\/strong>.<\/p>\n

\"\"<\/a>

Click Hierarchy<\/p><\/div>\n

2. Select a hierarchy from the drop-down list, navigate through the hierarchy to find your entity, and click the Attributes<\/em> button to the right of that entity.<\/p>\n

In our example tutorial, we select the P2 Energy Solutions<\/em> hierarchy, and navigate to Derby<\/em> entity: New South Wales>Far North Coast>Glen Innes>Central>Derby<\/em><\/p>\n

\"\"<\/a>

Search the Hierarchy<\/p><\/div>\n

3. Select an attribute from one of the templates, and drag it onto the Tags List<\/em>. Now add another one in the same way.<\/p>\n

The attributes used in our example tutorial are: Derby[Water Injection Well]:THP!Actual<\/em> and Derby[Water Injection Well]:THT!Actual<\/em>.<\/p>\n

\"\"<\/a>

Drop Attribute onto Tags List<\/p><\/div>\n

Dropping a Tag into the Tags List<\/em><\/strong><\/p>\n

1. Click Tags<\/strong> on the View<\/strong> tab.<\/p>\n

2. Search for tags in the tags list that appears on a panel on the left. Drag and drop a tag onto the Tags List.<\/p>\n

Typing Values into the Tags List<\/em><\/strong><\/p>\n

You can type a known tag name or attribute name surrounded by curly brackets {}<\/strong>, for example: {gold} in the Tags List<\/em>, and then press enter.<\/p>\n

You can also type in a calculation, also surrounded by curly brackets {}<\/strong>, for example: {Derby:THP} * 2. Note that the attribute in this list only requires the entity name and attribute name (template name and attribute value are optional).<\/p>\n

The video below demonstrates how you would type in a tag name.<\/p>\n\r\n\t\r\n\t

 <\/p>\n

Step 3. Changing Trend Selections<\/h4>\n

In this step, we'll experiment with changing the Time Range<\/em>, Sample Method<\/em> and Sample Interval<\/em>, and the Y Scale Type<\/em>. Note that the selections affect how much data is returned, thus affecting the time taken to render the trend.<\/p>\n

Step 3.1. Changing the Time Range<\/strong><\/p>\n

The defaults are: From 1 week<\/em> to current date and time<\/em><\/p>\n

Select 3 months<\/em> from the Time Range<\/strong> drop-down list. Note how the trend range now extends for three months.<\/p>\n

\"\"<\/a>

A Trend Spanning 3 Months<\/p><\/div>\n

Note: <\/strong> If you select a long time range (such as three months or longer) there will be a lot of data returned, which will take longer than if you select a short range, such as 1 week<\/em>.<\/p>\n

Step 3.2. Changing the Sample Method<\/strong><\/p>\n

The default is: Average<\/em><\/p>\n

Select Linear Interpolate<\/em> from the Sample Method<\/a><\/strong> drop-down list.<\/p>\n

\"\"<\/a>

Trend with Linear Interpolate Sample Method<\/p><\/div>\n

Note:<\/strong> Raw<\/em> sample method will usually return the highest number of data points, potentially affecting performance.<\/p>\n

Step 3.3. Changing the Sample Interval<\/strong><\/p>\n

The default is: 1 day<\/em><\/p>\n

Select 2 weeks<\/em> from the Sample Interval<\/a><\/strong> drop-down list.<\/p>\n

\"\"<\/a>

Trend with 2 Weeks Sample Interval<\/p><\/div>\n

Note:<\/strong> The shorter your interval (for example 5 seconds<\/em> ) the more data required, potentially affecting performance.<\/p>\n

Step 3.4. Changing the Y Scale Type<\/strong><\/p>\n

The default is: Linear<\/em><\/p>\n

Select Log<\/em> from the Y Scale Type<\/strong> drop-down list.<\/p>\n

\"\"<\/a>

Trend with a Y Scale Type of Log<\/p><\/div>\n

Note:<\/strong> Negative or zero values cannot render in the logarithmic scale type.<\/p>\n

Step 4. Changing your Time Selection with the Range Selector<\/h4>\n

The Range Selector<\/em>, found below the Trace<\/em>, works together with the Time Range<\/em> selectors to set your trend time range. By default, the range selector has a highlighted section that matches the time range set by the date pickers, with an equal amount of time shown before and after.<\/p>\n

\"\"<\/a>

The Trend Range Selector<\/p><\/div>\n

Resizing the highlighted section<\/em><\/p>\n

1. Hover the mouse over the left or right edge of the highlighted section, until you see the mouse horizontal resize<\/em> pointer.<\/p>\n

2. Now click and drag to left or right. Note how the trend start and end time changes.<\/p>\n

Moving the highlighted section<\/em><\/p>\n

1. Hover the mouse over the central portion of the highlighted section, until you see the mouse move<\/em> pointer.<\/p>\n

2. Now click and drag the whole highlighted section to left (earlier) or right (later). Note how the trend start and end time changes.<\/p>\n

Changing the Range Selector start and end dates<\/em><\/p>\n

Click on the left or right arrow to move the start and end date of the range selector. Note that the dates on the highlighted section do not change; the highlighted section just moves across (to left or right) in relation to the changing start and end dates of the range selector.<\/p>\n

\"\"<\/a>

Moving the Trend Range Selector Start and End dates<\/p><\/div>\n

 <\/p>\n

The video below demonstrates the use of the range selector. Clicking Refresh<\/strong> resets the time range.<\/p>\n\r\n\t\r\n\t

 <\/p>\n

Step 5. Adding a Hairline and Comments<\/h4>\n

Add a hairline to view values (if any) for all trended tags at a particular point in time. You can leave a comment for a trended tag at the hairline point, or view and reply to other comments.<\/p>\n

\"\"<\/a>

Trend Hairline<\/p><\/div>\n

New Hairline<\/strong><\/p>\n

Click a point on the trace to get a hairline, a vertical line marking out this time, with an information box to the side.<\/p>\n

To remove the hairline, close information box (click X on the top right corner).<\/p>\n

To move the hairline, either drag it along the trace, or add a click another point on the trace.<\/p>\n

Hairline Date and Time<\/strong><\/p>\n

This is displayed at the top of the information box, ordered by highest to lowest tag value at the hairline point.<\/p>\n

Each tag is identified by its trace legend and its full name. The tag value (if any) is displayed to the right, followed by a comment icon.<\/p>\n

Adding a Comment<\/strong><\/p>\n

To add or view comments, click the comment icon for a tag. See below for more on comments.<\/p>\n

The video below demonstrates working with hairlines and comments.<\/p>\n\r\n\t\r\n\t

Step 6. Adding, Viewing and Replying to Comments on a Trend Tag<\/h4>\n

Comments can be added to tags on a trend. You can reply to comments, locate comments on a trace, and even search for a range of comments by changing the search times in a comment window for a particular tag. All tag comments within the range are listed in the comment window, in order of most recent<\/p>\n

Note that you cannot remove comments.<\/p>\n

\"\"<\/a>

Tag Comment Search Times<\/p><\/div>\n

Step 6.1. Adding a Comment<\/strong><\/p>\n

1. Click the comment icon on the hairline information box, to open a blank comment window.<\/p>\n

2. Type in a comment, then click Add<\/strong>.<\/p>\n

\"\"<\/a>

Add a Comment<\/p><\/div>\n

Step 6.2. Replying to Comment<\/strong><\/p>\n

Comments are indicated on the trace by a vertical, dotted line.<\/p>\n

1. Click the comment icon to open the comment window. (You can click the comment icon again to close the comment window.)<\/p>\n

\"\"<\/a>

Locate and Open the Comment<\/p><\/div>\n

2. In the comment window, click reply<\/em>, then type in a response and click Add<\/strong>.<\/p>\n

\"\"<\/a>

Reply to the Comment<\/p><\/div>\n

Step 7. Saving Your Trend<\/h4>\n

Open the Trend<\/strong> tab on the Explorer ribbon, and click Save<\/strong>.<\/p>\n

\"\"<\/a>

Click Save on the Trend Ribbon<\/p><\/div>\n

The Save Trend<\/em> window opens. Type in a Name<\/em> for your trend, and select a Workspace<\/em> from the drop-down list, or click Create new workspace<\/em>, then click Save<\/strong>.<\/p>\n

\"\"<\/a>

Save Trend<\/p><\/div>\n

Step 8. Search for a Trend<\/h4>\n

Now that you have created and saved your trend, here is how you can find it again:<\/p>\n

1. Open the Home<\/strong> tab on the Explorer ribbon, and click Workspaces<\/strong>.<\/p>\n

2. Click the workspace that contains the trend (for example, Tutorials<\/em>).<\/p>\n

3. Click Trends<\/strong> in the main area.<\/p>\n

4. Type the trend name in the Filter Trends<\/em> search box.<\/p>\n

5. Click on the trend thumbnail to open it.<\/p>\n
