Bar graph: Bar group
Properties in this group control the appearance of the graph’s bars, including gradient style, color, and fill style. The group also includes properties that control the visibility and appearance of the text used to display bar values, including font, color, size, and position. You can also specify an image to be displayed within each bar.
Bar group properties
This group contains the following properties:
barGradientStyle
Select one of the following in order to set the gradient style of the bars:
None: Default setting.
Shaded: Display bars with a flat gradient
Rounded: Display bars with a rounded gradient
This property is in the Bar property group.
barImage
Specifies an image (.gif, .jpg, or .png file) to display in each bar. Select the name of the image file from the drop down menu, or enter the pathname of the file. The drop down menu contains the names of image files located in the current directory (typically, the dashboards directory of your project directory, under your Apama installation’s work directory), as well as image files located in the first level of subdirectories. If you enter a pathname, use an absolute pathname or a pathname that is relative to the current directory.
Note: If necessary, the image will be stretched to fit the bar size.
This property is in the Bar property group.
barProperties
Specifies the color and fill pattern for each bar in the graph. In the Object Properties window, double-click on barProperties in the Property Name field to bring up the Bar Properties dialog. In the Bar Properties dialog you can assign attributes to each bar in a bar graph.
The dialog contains three columns of fields:
Bar: There is one entry for each bar that is currently displaying data in the bar graph. The Color and Fill Pattern columns list the current settings for each bar.
Color: Select the ellipsis button in the Color column and choose a color from the palette to set the color of the bar. Close the Color Chooser window.
Fill Pattern: Select the ellipsis button in the Fill Pattern column and choose a pattern from the palette to set the fill pattern of the bar. Close the Fill Pattern window.
Note: The fill patterns in your bar graph are ignored unless the
barGradientStyle property is set to
None.
The dialog contains the following buttons:
Add Bar Property: Click to add a Bar Property entry. This does not add a bar to your graph, it adds a bar entry so that you can set properties for bars that will display data that is not yet available. This is useful if the data attachment is not available when you setup your bar graph, or if the number of rows or columns returned by your data attachment varies.
Delete Bar Property: Removes the last bar property entry from the
Bar Properties dialog.
OK: Applies values and closes the dialog.
Apply: Applies values without closing the dialog.
Reset: Resets all fields to last values applied.
Clear: Clears all fields. Detaches object from data source (once Apply or OK is selected).
Cancel: Closes the dialog with last values applied.
