Bar graph: Interaction group

Properties in this group control various forms of interaction between the end user and the graph, including scrolling, highlighting, and activating commands, drill downs, and tooltips.

The group includes the following properties:

Assign a command or group of commands to this stock chart by right-clicking on the command property name in the Object Properties window. Select Define Command and choose SYSTEM, APAMA, or MULTIPLE. For information on the Define Command dialog, see Building Dashboards in Developing Apama Applications.

Once a command or command group has been assigned to this object, you can activate it from a deployed dashboard or from the Dashboard Builder:

Web-based deployment: Single click on the object or else right click on it and select Execute Command from the popup menu.

Local deployment: By default, single-click on the object or else right-click on it and select Execute Command from the popup menu. To override the default, select Tools > Options in the Builder (do this before you generate the deployment package), and uncheck Single-Click for Drill Down and Commands in the General tab. This allows the end user to use either a double click or a right click.

When you activate a command, any defined drill down substitutions are performed, and then the comand is executed.

If you assign multiple commands, the commands are launched in an arbitrary order, and are executed asynchronously; there is no guarantee that one command will finish before the next one in the sequence starts.

This property is in the Interaction property group.

Select this property to automatically close the window that initiates a SYSTEM command when the command is executed successfully. This applies to SYSTEM commands only, and is not supported at all for thin-client, Web-page deployments.

With APAMA commands, the window is closed whether or not the command is executed successfully. For MULTIPLE commands, the window closes when the first command in the command group succeeds.

This property is in the Interaction property group.

By default, when the end user executes a command (see the command property), the command confirmation dialog is disabled. To control this option for each individual object, use the commandConfirm check box. If confirmation is required for a MULTIPLE command group, a single confirmation dialog is presented; if you confirm the execution, all individual commands in the group are executed with no further confirmation. If the you cancel the execution, none of the commands in the group is executed.

You can also override the confirmation status of individual objects with an application-wide policy. Select Tools | Options and choose from three confirmation values:

Do not confirm: Indicates that no commands require confirmation (regardless of each object's confirmation status).

Confirm all: Indicates that all commands require confirmation (regardless of each object's confirmation status).

Use object confirm flag (default): Indicates that the confirmation status of each object will determine whether confirmation is required.

This property is in the Interaction property group.

Use this property to write your own text for the confirmation dialog. Otherwise, default text is used. See commandConfirm.

This property is in the Interaction property group.

Use this property to direct a dashboard to assign data-table column values to specified dashboard variables when the end user activates a drilldown on this object. In the Object Properties window, double-click on drillDownColumnSubs in the Property Name field to bring up the Drill Down Column Substitutions dialog.

The dialog has the following fields and buttons:

Substitution String: Enter the dashboard variable next to the name of the data table column whose value you want assigned to the variable. Press Enter.

Add Column: Enter the name of a column and click the Add Column button to insert a column into the table.

The Column Name list is populated based on the table's data attachment. If you have not yet attached the table to data, this list is empty.

Once you have selected which column values to pass in as substitutions, double-click on any element in your object to open a drill down window that displays corresponding values.

This property is in the Interaction property group.

Use this property to control how a drill down display is activated. Select one of the following:

Element Only to enable a drill down display only when you double-click on an element of the chart, such as a bar or candlestick.

This property is in the Interaction property group.

To specify a drill down display, double click on drilDownTarget in the Property Name field to bring up the Drill Down Properties dialog. See Drill-Down Specification.

This property is in the Interaction property group.

Select this property to enable tooltips for your bar graph. To display a tooltip, point to a bar or trace marker with your mouse. The tooltip will contain information from your data attachment about that bar or marker.

This property is in the Interaction property group.

Select this property to enable bar highlighting. To highlight a bar in red, point to the bar.

This property is in the Interaction property group.

Select one of the following to set the behavior of the x-axis scroll bar in the graph:

As Needed: Display the scroll bar when there is not enough space to display all of the bars in the plot area. Each bar uses at least minSpacePerBar pixels along the x-axis.

This property is in the Interaction property group.

Specify the height of the horizontal scroll bar and the width of the vertical scroll bar, in pixels.
