Adding a Numeric Action Slider


The Numeric Action Slider allows the entry of a numeric parameter.

Whenever the slider value is changed, the associated action is executed.


1.     After double-clicking or drawing a rectangle on the dashboard canvas, click  on the Select Part pane then click the Numeric Action Slider  icon.

The Numeric Action Slider pane is displayed, and the Numeric Action Slider part is added on the dashboard canvas.

For this example, the following parameters are defined:

Parameter Name


Default Value




Slider Value




These parameters are used on the Title of the Line graph (e.g., Price History for {Ticker} with Slider Value = {Slider Value:0.00%}).


2.     The numeric action slider can be configured to either be a Standalone or a Form component.

When set to Form, the numeric action slider can be connected to any form controller on the same dashboard. The parameters that the action part can set depends on how the form is configured.



An action form part must be defined first to associate the numeric action slider as a component. Refer to Adding an Action Form more information.


A line connects the component to the associated form.


If the numeric action slider should not be connected to a form, it can be set to Standalone instead. Select the Target Parameter that will be updated by this action part.
