Analysis Charts

About Analysis V2 Charts

Analysis V2 charts appear on cards contained in a view.

Features:

You can save Alert Analysis and Analysis View charts as Analysis Templates.
You can select multiple groups containing multiple charts.
When you add a chart to an Alert Template, any triggered alerts appear in the Alerts module, where they can be examined.
You can access public or private templates, or a new Time Series Analysis or Event Data Analysis view in the View Selector.
You can access data related to assets that are not available in Essentials by importing the data. The data is then used to create tags.
You can specify whether a template is public or private.
You can specify whether a template is for an instance or a class.
You can set the time zone, data resolution, data source, system of measure, and data quality of a chart. However, these settings are not available for SmartSignal charts.
The default date range for an Alert Analysis is seven days before and after the event date. However, if the current date is earlier than the end date, the current date is considered.
The default start date for a Time Series Analysis View is 15 days prior to the current date.

The selected configuration or the default value for the Time Zone (), Data Resolution (), Data Source (), System of Measure (), and Data Quality () drop-down list boxes appears for each settings option. You can select different options in these list boxes. These options are not available for SmartSignal charts.

The Event Data Analysis View uses a selected number of events prior to a date and time selected by you to determine the time range for the selected event type. You can also select the number of seconds pre- and post-events to refine the amount of data surrounding the selected events.

As you plot tags for an Alert Analysis View or a Time Series Analysis View, a Plotted Tags list appears in the Plotted Tags section. The list appears as a hierarchy with nodes for cards and charts, and plotted tags or plotted tag series listed below.

Event Data Analysis view chart types are limited to Time Series, X-Y, or Polar charts. After you have selected the number of events for an Event Data Analysis view, added two tags, and selected View Data, an Event Frames list appears in the Tag Tree Browser that contains the number of events selected. Each event is identified by a date and time and is global for the all charts on the view. As you add cards and plot tags, a Plotted Tags list appears in the Plotted Tags section. Tags are represented below the main card node. You cannot manipulate tags in the Plotted Tags list. Muting and unmuting of data is controlled in the listed event frames, not the plotted tags. The Event Data Analysis View does not support multiple assets.

The tag name, correlated tags, unit of measure, a description, and the asset appear on the Tag Information Table. Tag information is hidden by default.

Note: The Tag Information Table does not appear on an Event Data Analysis View.

You can sort by the following values:

Tag name
Data point or value
Unit of measure (UoM)
Muted tags

You can also perform the following tasks:

Show tag information.
Configure analysis chart settings.
Add a chart below the selected chart.
Modify a chart.
Arrange a chart.

Note:

Selection of common chart controls such as zoom, cross-hair, and so on is applied across all the charts in a card and also across all the charts in any other card in the view. Any new charts added to the cards also retain the common chart controls selection made in one card. Deleting the chart or the card or moving to another card does not change the common chart controls selection. The sub configuration options of the common chart controls do not open for all the charts on which the selection is propagated.
The common chart control selections are reset when you select another chart control outside the common controls and refresh the chart.
When navigating to Analysis V2 from an Alert, the selection of common chart controls is retained on the charts.
The selection of common chart controls is retained on the Event Data Analysis charts.

Create a Time Series Analysis Chart

Use Time Series Analysis to review data requests or to create new analysis view templates.

About This Task

You can select the type of adhoc analysis charts with which you want to work. The Time Series Analysis uses time series data for the asset context you select. You can save a Time Series Analysis view as a template, which can then be applied to an Alert Template, triggering an alert in the Alert module.

You can add additional assets, add cards and charts, select a layout, change the date range, mute and unmute tags, plot tags, filter tags, plot tag expressions, and make other necessary modifications. You can plot up to 70 tags in a Time Series Analysis chart.

You can create a new ad hoc analysis without saving the one on which you are currently working. When you navigate away from the current ad hoc analysis, a message appears, indicating that you will lose unsaved changes to the current ad hoc analysis view. Select Continue to create a new view with no tags plotted.

Note: Consider saving the current ad hoc analysis as a template prior to navigating away.

Procedure

In the Applications menu, navigate to the HEALTH section, and then select Analysis V2.
Select Create Analysis > Time Series Analysis.
In the Asset Hierarchy, select an asset context.
The Time Series Analysis view appears with no tags plotted.
In the Select chart type box, select a chart type.
From the TAG BROWSER section, drag and drop the tags that you want to plot. You can plot tags that use different units of measure, displaying multiple y-axis numbering systems.
The Time Series Analysis chart is created.
Modify the chart as needed. For example, you can set the data source, data resolution, system of measure, and data quality.

About the Timing Diagram Chart

Using the Timing Diagram chart, you can analyze trends/patterns in data. It plots observations on the y-axis and time interval on the x-axis.

You can create a Timing Diagram chart from a Time Series Analysis template only. To create the chart, you must select the time range and add multiple tags. You can then compare multiple charts on the same card. The Plotted Tags section in the Tag Browser displays a hierarchy of the card, charts, and tags plotted on the chart in the view.

You can drag and drop tags from the Plotted Tags section to the two overlays that are available:

Logical Overlay: Logical tags are plotted on Y-axis as a stack. Each tag appears as a straight line with a unique color to identify the tag from the tag register. However, tags with values other than 0 or 1 are represented in a step-up manner in the chart.
Standard Overlay: Standard tags are plotted linearly

You can plot up to 40 tags on a chart, up to 20 of which can be logical tags. When you pause over a tag, the value of the logical tag appears in the tag register.

You can save the chart as a template.

Create an Event Data Analysis Chart

Use Event Data Analysis to review event data, or create new analysis view templates.

About This Task

Event Data Analysis allows you to compare the same event occurrence over time to see if it indicates a gradual degradation of an asset.

You can select the type of ad hoc analysis with which you want to work. The Event Data Analysis uses event-based data for the asset context you select. You can save an Event Data Analysis view as a template.

Note: You cannot save an Event Data Analysis template to an Alert Template.

You can save an Event Data Analysis view as a template, which can then be applied to an Alert Template, triggering an alert in the Alerts module.

The Event Data Analysis charts rely on the selection of an Event Type. Event Types are garnered from Alert Types, which are created for Alert Templates during tenant on-boarding.

Just as with Time Series Analysis charts, you can add cards and charts, select a layout, mute and unmute events, plot tags, filter tags, plot tag expressions, and make other necessary modifications. Event Data Analysis charts are event-frame-centric instead of tag-centric. Event Frames are the timestamped, prior instances of the selected Event Type. You can plot up to 70 tags in an Event Data Analysis chart.

You can select the number of events in the charts, determine the number of seconds prior to and after each event, and determine the date and time ending the event search to appear. The default ending time is the present date and time.

If you change any of the settings for the charts, you must select Update to make the changes in the charts.

Event Data Analysis charts have some limitations:

You cannot add multiple assets in the Tag Tree Browser, Tag Expressions or Search Browser panes.
You can add up to 40 events per tag in an Event Data Analysis.

Note: Consider saving the current ad hoc analysis as a template prior to navigating away.

Procedure

In the Applications menu, navigate to the HEALTH section, and then select Analysis V2.
Select Create Analysis > Event Data Analysis.
In the Asset Hierarchy, select an asset context.
The Event Data Analysis view appears with no tags plotted.
In the Select chart type box, select a chart type.

Enter values as described in the following table.


Field	Description
Event Type	Select the event type.
Events	Enter the number of events.
TO	Select the event end date and time.
Pre-Events and Post-Events	Enter the number of seconds of data before and after the event to appear.

As needed, set the data source, data resolution, system of measure, and data quality.
Select Apply.
From the TAG BROWSER section, drag and drop the tags that you want to plot. You can plot tags that use different units of measure, displaying multiple y-axis numbering systems.
The Event Data Analysis chart is created. Data for the number of selected events appears on the chart, and each event is listed in the Event Frames section in the Tag Browser. The Plotted Tags section contains the card names, chart names, and tags that are plotted for each card and chart.

Reorder Axes on a Chart

When you drag tags into a Parallel Axis chart, the order in which you plotted the tags matches the displayed order of the axes on the chart. You can change the order of the Y-axes after you have plotted at least three tags.

Before You Begin

Plot at least three tags on the chart.

Procedure

Access the chart for which you want to reorder the axes.
Perform one of the following tasks:
- Select a previously-saved Parallel-Axis chart.
- In Ad Hoc Analysis, select Parallel Axis from the Add Chart menu, and then plot at least three tags.
Select , pause over a vertical axis on the chart, and then drag and drop it to a new location on the chart.
All axes move over to accommodate the relocated axis.

Emphasize Data on Vertical Axes for a Chart

To manage tags, you can emphasize data on multiple chart axes, and select multiple areas on one axis to emphasize.

About This Task

You can de-emphasize extraneous data for Y-axes, displaying the irrelevant data as faded lines. You also can resize the selector boxes added to an axis.

Procedure

Access the chart on which you want to emphasize data.
Perform one of the following tasks:
- Access a previously saved Parallel Axis chart.
- Select Add Chart > Parallel-Axis, and then plot three tags.
Select , and then drag over a selected portion of the vertical axis.
To select a data portion to emphasize:
1. Select , and then drag your cursor over a selected portion of a vertical axis.
  A selector box appears. Data within the scope of the selector box is emphasized. Data not in scope is de-emphasized.
To enlarge or reduce the area, select one end of the selector box and drag to make the area larger or smaller.

Access Data Points on Charts

About This Task

You are able to select a section of data points in a chart and have that same time reflected across all the charts in a template. This is available for Time Series charts, X-Y charts, and Polar charts.

Procedure

In the Applications menu, navigate to the HEALTH section, and then select Analysis V2.
Access an analysis chart displaying plotted tags.
Select , and then highlight the data points you want to access.
When you select a period of time on a chart by marking a block on the chart, all the other charts in the card highlight the same period of time represented by the points selected on the chart. You can only highlight one chart at a time.

Filter Data Points on Charts

About This Task

You can filter selected data points in a chart and have the same time reflected across all charts in a template. You can filter data such that the selected data is either included or excluded in all the charts. This helps you to focus on the relevant data based on the selected data points and filter options in lasso selection. You can also use the lasso selection on a chart to filter out data in combination with other filters such as condition and value-based filters, zoom options, and mute tags options. This feature is available for Time Series charts, Parallel Axis, X-Y charts, Spiderweb, and Bar charts. You can enable this feature only in the Time Series Analysis and the CSV Analysis views.

Procedure

Access the chart whose data you want to filter.
Select .
By default, the selection is enabled. Using this option, you can select data points on both the x-axis and the y-axis. Alternatively, you can select or to select along the required axis only.
Select the data points that you want to filter.
Select or to include or exclude the selected data points in the visualization.
Note:
- The filter options become active only when you select and apply either xy-axes, x-axis, or y-axis options in the chart.
- The highlights on the data points based on earlier selections in the chart are removed when you select filter-in or filter-out.
Redraw data points in the chart and axis labels.
Based on the axis and filter options, the selected values appear or are excluded in the visualization. A message appears on the chart, indicating that the lasso filter is applied to the chart.
- If you navigate to analysis from alerts or cases and apply lasso filter selection to the data in the chart, you can save the selection state as an evidence to an alert or a case. You can access the chart evidence from the alert or case, modify the lasso filters and update the evidence, and save it again to the alert or case by overwriting the existing evidence or save it as a new evidence.
- You can filter data for lasso selections on a chart for selected time ranges, such that the selected data is visible in all the charts or excluded from the charts. The same time range is reflected on all the charts in a template.
- You can zoom the chart if the selected time range is at the beginning or end of the chart time range.
- The Lasso Filter Applied indicator appears for all charts in the card that are synchronized when the lasso filter is applied.

Upload a CSV file

About This Task

You can view data of assets that are not available in the Essentials server and visualize the data using the tags that are created for the uploaded data.

The CSV file must contain data in a specific format following certain conditions; otherwise, the upload fails. Based on the data that you have uploaded, tags are created. The tags are used to plot and export charts to visualize the data. The following is a sample of the CSV file.

The CSV file must include the following data:

Tag Name
Note:
- The tag name can include special characters.
- Each AssetName can be combined with the TagName, for example G12.DWATT.
Date and Time
Data for each tag

The CSV file must meet the following conditions:

The file format must be .csv or .xlsx.
The columns between the tag keywords and tag name must not be blank; all other columns can be blank.
The Tags and description keywords columns must have the timestamps for the tag data in the column that follows the tags.
The Tag column names must be prefaced with the keyword Tag/Tags.
The UoM column names must be prefaced with the keyword Unit/Units.
The tag description column name must be prefaced with the keyword Description.
The keyword prefixed rows must be placed before the timestamp data rows.
Rows with a NaN timestamp are not considered.
For a blank or a non-numeric data row, the column data for the tag is considered as NaN.

Note: When you upload an .xlsx file, the timestamp that appears does not show the seconds and milli-seconds. Hence, if the timestamp values are required, you must format the values in the excel column and save it before you upload the file. mm/dd/yyyy hh:mm:ss AM/PM is a sample format you can use to format the timestamp values.

Procedure

In the Applications menu, navigate to the HEALTH section, and then select Analysis V2.
In the Asset Hierarchy, select an asset context.
Select New CSV Template.
Select Choose File, browse through the files on your computer, select the .csv or .xlxs file that you want to upload, and then select Create.
The file is validated and then uploaded. After the file is uploaded successfully, the CSV Visualization Asset appears in the Tag Browser. You can expand CSV Visualization Asset to view the tags that are created based on the data available in the uploaded file.

What To Do Next

Plot charts using the tags to analyse the data for the virtual assets. You can only view the chart but cannot save it.
Export the chart.

Delete a Chart

If you delete a chart, all tags, reference curves, and tag expressions unique to the deleted chart are removed from the plotted tags list.

Procedure

Access the chart that you want to delete.
Select .
The chart is deleted and all its unique tags are removed from the Plotted Tags section.
