You can view each data value for a stream by choosing it from the Sequential Data Store.

-
Select View Data.
By default, the last data value available for the stream displays. However, you can change which data values are displayed by editing the Query Type dropdown. See the heading below for more information.
Tip: You can manually add data values to a stream by adding an event. For more information, see Add event.
Edit query type
Edit the query type for the stream to view its first value, last value, or a range of data.
To edit the query type, ensure that the First Value/Last Value/Range Query button is enabled. Then select a value from the Query Type dropdown.
|
Query Type |
Description |
|---|---|
|
Get First Value |
Gets the first recorded value for the stream. |
|
Get Last Value |
Gets the last recorded value for the stream. |
|
Get Range Values |
Gets a range of recorded values for the stream. For more information on setting a range, see the heading below. |
Range values
Ranged value queries get a range of recorded values for a stream. You can either query by count of data points or by range between a start and end index.
To query by count, select By count and configure the following parameters:
|
Parameter |
Description |
|---|---|
|
Start Index |
The start index for the range. Choose a date and time. By default, this value is the current date and time. |
|
Count |
The maximum number of data values returned by the query. By default, this value is 100. |
|
Reversed |
The order that data is queried from the start index—forward or reversed. When set to True, the query returns data searching reversed through time (reverse chronologically). When set to False, the query returns data forward through from the provided start index (chronologically). By default, this setting is set to True. |
To query by range, select By range and configure the following parameters:
|
Parameter |
Description |

Select Apply to apply your parameters and execute the query. The data values included in the query are listed on screen, and they are plotted in a graph as well. For streams with multiple properties, you can view different data values included in the stream by editing the X Axis and Y Axis dropdowns, as depicted in the image below.
