Step chart

Generates a step chart for a data set, with the option to add drill-down trees for additional data sets. You must populate the data set by using a service.

Configuration properties

Under Configuration, set or modify the appearance and behavior properties for the view.

Screen size: A configuration property that has the Screen Sizes icon beside the property name can have different values for each screen size. If you do not set a value, the screen size inherits the value of the next larger screen size as its default value.

Theme definitions: Theme definitions specify the colors and styles for a view and determine its appearance. You can preview the look and feel of views in the theme editor. See Themes.

Restriction: If you encounter sizing problems when you display the chart in a collapsible panel, use the following code on the On expand event of the collapsible panel to adjust the chart size to the available space: ${CHART_CONTROL_ID}.refresh();

The appearance configuration properties for Step chart are shown in the following table:

Data series custom color style	Customize the color style for the data series. In the `NameValuePair`, `Name` is the series name and `Value` is the color specified as name, hexadecimal code, or RGB code. For example, `red`, `#ff0000`, `rgb(255, 0, 0)`. The property takes precedence over Data series color style.	`NameValuePair`
Show value labels	Display data point values above each point in the chart.	`Boolean`
Show breadcrumbs	When this option is enabled, the title shows the current position of the tree that the user can drill down into (depending on the menu selection).	`Boolean`
XY axis color style	The color style for the X and Y axes.	`String`
Gridlines style	The style for the horizontal gridlines.	`String`
X label rotation	The rotation in degrees for the X-axis label.	`Decimal`
X axis height	The height of the X axis.	`Integer`
Border radius	The radius of the chart.	`String`

The behavior configuration properties for Step chart are shown in the following table:

Table 2. Behavior configuration properties for Step chart
Behavior configuration property	Description	Data type
Chart data mode	Select whether to populate chart data from a service or from the configuration option. Note that trees users can drill down into are available only by populating through a service flow with appropriate Ajax access.	`String`
Data service	A service that populates the data series.	`Service Flow`
Data series	The `seriesName` is the name for the data series and `dataPoints` is the list of data points to include in the data series.	`String` for the `seriesName` and `DataPoint[]` for the list of `dataPoints`.
Enable menu	Enables the visibility of the menu. The menu is required if you have a tree that users can drill down into, or if you added menus.	`Boolean`
Number of Y axis ticks	The number of ticks on the Y axis. The value that you specify is not interpreted as an exact number but is adjusted to the best suitable tick count to provide optimal display.	`Integer`
Y axis tick precision	The number of decimal places to display for Y-axis value labels. The default number of decimal places is 0.	`Integer`
Min Y axis value	The minimum value on the Y axis.	`Decimal`

Use X axis culling	Show only the number of X-axis data tick counts, which is determined by the value of the Max X tick count property.	`Boolean`
Number of X axis ticks	The number of ticks on the X axis. The value that you specify is not interpreted as an exact number but is adjusted to the best suitable tick count to provide optimal display.	`Integer`
Show tooltip	When this option is enabled, hovering over data points in the chart with the mouse causes a tooltip to appear. The tooltip shows both the name of the point and its value.	`Boolean`
