Charts
About Charts
You can use charts to evaluate asset data using various views.
- You can access a collection of tags, tag attributes, and tag expressions that are associated with a chart within the Analysis template. Some charts use pairs of tags where the actions are based on the pairs rather than the individual tags.
- When creating a chart, you can save the analysis view, making it available as a Analysis Template.
- You can set your timezone preference and data resolution. Important: Data resolution and date range selected are related.
- You can add different chart types to a single card. For information on the minimum number of tags required to create a chart, refer to Chart Types.

Access a Chart from an Alert
You can use an Analysis View template to review performance charts associated with an alert and to gather evidence to help resolve the alert. This is applicable to both Asset Data and SmartSignal alerts.
About This Task
When an asset source connects to the time-series database, designated analytics parse the data using threshold values. If one or more threshold values are not met, Essentials generates an alert using an associated alert template.
Analysis View templates automatically populate the asset and assign a default time range and view for the chart.
When you select a SmartSignal Analysis View chart in an alert, all of the generated alerts for the selected asset are visible in the Tag Browser.
Procedure
Add a Chart to a Card
You can add multiple Analysis V2 and SmartSignal charts to a card. You can add up to 60 charts to a card. You can then modify the chart name, select a chart type, and then begin plotting the chart.
Procedure
What To Do Next
Arrange the Chart Order on a Card
Procedure
Resize a Chart
A default size is set for a chart based on user preferences. You can increase the height of a chart to improve the vertical resolution and view a clearer picture.
Procedure
- Access the chart that you want to resize.
- In the page heading, select
, and then select the size based on your requirement. You can also pause over
in a chart to increase the chart size to extra large or return to the default size.
Export a Chart
About This Task
- PNG
- CSV
- The chart image
- All legends on the axes
- The chart registers with the tag names and asset names
If the UoM of a chart has been changed, the standard UoM appears in the exported file; otherwise the source UoM appears.
This topic describes how to export a single chart. If you want to export all the charts on a card, refer to Export a Card.

Procedure
What To Do Next
- Save the chart as a template.
- If you have added threshold lines to an existing template, modify the template to save your changes.
Zoom in Chart Data
About This Task
- Along the x-axis: Allows you to control the time range available for analysis. This method is applicable to Time Series and X-Y charts only.
- Along the y-axis: Allows you to control the range of values that are relevant for the analysis. This method is applicable to Time Series and X-Y charts only.
- Along both the axes: Allows you to zoom in along both the axes, based on the center of the chart. This is the default option.
- You can undo or reset the zoom settings.
- When you zoom in a chart, the data resolution is set to default or the actual number of data points, whichever is less.
- If there are multiple charts in the view, zooming in one of the charts magnifies the remaining charts as well.
- The zooming in setting is synchronized across Analysis charts or SmartSignal charts but not both.
Procedure
Reset Zoom for Chart Data
Resetting the zoom for a chart removes all the zoom settings that you have applied.
About This Task
Adding a new tag resets the zoom settings automatically. However, muting or unmuting a tag does not reset the zoom settings.
Procedure
Add a Chart as an Evidence in an Alert
You can save an Analysis V2 chart as evidence in an alert so that others can see the health of the asset without having to access the Analysis V2 module.
Before You Begin
About This Task
Procedure
Add a Chart as Evidence in a Case
You can save an Analysis V2 chart as evidence in a case so that others can see the health of the asset without having to access the Analysis V2 module.
Before You Begin
About This Task
- When an analysis template associated with a certain alert triggers the alert, it creates a case in the alert. You can view the case that is generated by the alert. You can then navigate to the Analysis section in the Case Detail page where you can view the templates associated with the alert and the name of the alert.
- When a large number of analysis templates (for example, 20) are associated with an alert, if the alert triggers and a case is created from that alert, you can view the Analysis section in the Case Detail page, which lists all of the analysis templates with the alert name as the source.
Procedure
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.
