Data Tip View
For a Table data-tip, enable 'Shrink to Fit' in the Table Properties to minimize the data-tip footprint.
A Data Tip displays information about the current chart or table region using another Viewsheet component, such as another chart, text, Gauge, or Organization Components. The data tip is displayed as a tooltip (next to the pointer), and is adaptively filtered to show only data corresponding to the particular region of the chart or crosstab where the pointer is positioned. If the data tip utilizes a table or chart, the export features of the table or chart remain available in data tip view.
Walkthrough
In this example, you will create a chart that displays quantity purchased by company. When the user hovers the mouse over a given company, the Chart will display a Gauge as a Data Tip. This Gauge will display the average quantity purchased by the individual company.
1. Create a new Viewsheet based on the sample 'US Sales' Worksheet.
2. Drag a Gauge from the Component tree into the Viewsheet.
3. Configure the Gauge to display the average quantity purchased:
a. From the 'Sales' Data Block (top of the Component tree), drag the 'Quantity Purchased' field onto the Gauge. This binds the Gauge to the Data Block.
b. Right-click the Gauge, and select 'Gauge Properties' from the context menu. This opens the 'Properties' dialog box for the Gauge.
c. Under the General tab, change the 'Name' property to “QuantityGauge”.
d. Set the following limits: 'Maximum'=200, 'Minor Increment'=10, 'Major Increment'=25.
e. Under the Data tab, select 'Count' form the 'Aggregate' menu. This will display the number of records (orders) for each company.
f. Click 'OK' to close the 'Gauge Properties' dialog box.
g. Resize the Gauge to be about half the default size.
4. Drag a Chart element onto the Viewsheet grid.
5. Click the center of the Chart (or click the 'Edit' button at the top-right). This opens the Chart Editor. Make the following selections:
a. From the 'Dimensions' node in the Data Source panel, drag the 'Company' dimension to the 'X' field in the Data panel.
b. From the 'Measures' node in the Data Source panel, drag the 'Quantity Purchased' measure to the 'Y' field in the Data panel. This creates a chart that displays quantity purchased for each company.
c. Click the 'Edit Dimension' button, and select 'Ranking' to display only the top 10 companies. Click the 'Apply' button.

d. Right-click on the one of the Chart's X-axis labels, and select 'Axis Properties' from the context menu. Choose a slanted text rotation and a smaller font size to improve the axis appearance. Click 'OK'.
e. Resize the chart as desired.

6. Right-click the Chart, and select 'Properties' from the context menu. This opens the 'Chart Properties' dialog box.
a. Under the General tab, select 'Data Tip View'. From the adjacent menu, select the 'QuantityGauge' component.
b. To adjust the transparency of the data tip component (Gauge), enter a value in the 'Alpha' menu (or choose one of the preset values). A value of 0 indicates complete transparency; a value of 100% indicates complete opacity.

c. Click 'OK' to close the 'Chart Properties' dialog box.
Note: Data tips are not active in the Design view. Preview the Viewsheet to see them.
7. Preview the Viewsheet, and hover the mouse over different companies in the Chart to view the corresponding Data Tip (i.e., number of orders).

Note that the Gauge is not displayed as part of the Viewsheet layout. The Gauge appears only when you hover the mouse over one of the companies in the chart, and it then displays only the data for that particular company.
You can use a single component in both a Data Tip view and a Flyover View. If you designate a Data Tip component for Flyover duty, the component always remains visible on the Viewsheet.
