Adding a data source to an object
Creating and configuring data entities
Snapshots, tickers and multi-tickers are all data entities -- combinations of specific data
from a data source (more than one data source in the case of multi-tickers), and instructions
on how to display the data once it has been linked to an object (e.g. in ticker format, as a
snapshot value).
The following sections describe how to create and edit data entities:
•
“Creating a snapshot” on page 6-7
• “Creating a ticker” on page 6-9
• “Creating a multi-ticker” on page 6-11
• “Editing and deleting data entities” on page 6-12
• “Renaming or saving a copy of a data entity with a new name” on page 6-12
Creating a snapshot
A snapshot is a table of data values that is periodically refreshed. Use a snapshot to display
a single data value, in contrast to a ticker which cycles through a set of values.
To create a snapshot:
1.
Open Xpanel’s Asset Browser (Ctrl+A) and select the D ATA tab.
2. Right-click on the schema that you want to add the snapshot to and select the N EW
S NAPSHOT command.
The D ATA S NAPSHOT S ETTINGS window appears.
3. In the S NAPSHOT N AME field enter a name for your snapshot.
4. In the D ATA SOURCE drop-down list, select one of the data sources that is already
defined in the schema.
The Data Setting fields that are displayed depend on the type of data source selected.
If the Data source is an Excel Spreadsheet:
• Verify the E
XCEL FILE path (read-only) and specify the sheet name in the
S HEET NAME field.
If the Data source is a text file:
• Verify the T
EXT FILE path (read-only).
If the Data source is an RSS:
• Verify the URL path (read-only).
If the Data source is a database:
a.
Select one or more tables from the S ELECT TABLE ( S ) section (hold down the SHIFT
or CTRL key for multiple selections)
b. Select the columns to be returned from the query in the S ELECT R ETURN
C OLUMN ( S ). To change the titles of selected columns, click the E DIT C OLUMN
N AMES button. When the C OLUMN H EADERS dialog box displays, click in a column
name to make the text editable.
