Workflow Duration Chart Control

1. Create a view.
2. Drag the control onto the canvas. You can find the control in the Reports section of the Toolbox.
3. Configure the properties of the control to display the data you want in the chart.
4. Run the view.

You can find the control in the Reports section of the Toolbox.

Report controls interact with each other through rules. When you bind properties between different controls, you can use the data to populate properties or set values. See the following points for using rules with control properties:

• You can use the following property in the context browser when you use rules for mapping to other controls. This property is in addition to those mentioned in the Properties section of this topic, but is only available for interaction with rules:
  Selected Range - The range of the column you select. This property returns the start and end dates that you can use in other controls
  
• You can configure a rule to open the Workflow Duration Chart when you click a record in a Workflow Instances Chart. To do this, configure the following rule:
  
  

The following events and methods are available on the control:
Rule Events:

• When [control] is Changed: This event executes when the control is set to a new value that is different from the previous value. You can use this event to trigger actions when the control is changed, for example execute the Run method.
• When [control] is Clicked: You can execute a rule condition or action when the control is clicked, for example populate another control.
• When [control] is Populated: This event executes each time the control is loaded. You can execute a rule condition or action when the control is loaded, for example execute the Run method of another report control.

Control Methods:

• Execute a control's Clear method: Clears the workflow data from the control. You can use this method to, for example, clear the workflow data and then execute a Run method using rule mappings of a different workflow.
• Execute a control's Run method: Gets the data from the database, applies configuration and rule settings, and then displays a graphic representation of the average duration and count of workflow instances over time.

Security on the Report controls ensures that the data is seen by only those who are authorized. Permissions are based on the process rights assigned to the process in Management Site:

• Admin or View permissions: You can access the Report controls.
• View Participate permissions: You can view the Report controls from the point where you are part of the workflow.

• The control is also available when designing forms
• When you use the control together with the Save as PDF control, and you configure a percentage for the width of the control, a pixel width is calculated and used instead. When using the chart with the Save as PDF control, set the width of the control in pixels.
• When you use custom themes, be sure to specify the CSS classes for the elements.
• You can use reporting controls to access the data of workflows created in any workflow designer, including the K2 Designer and K2 Designer for SharePoint.
• Certain combination configurations can impact performance, for example when you use a range of 90 days, grouped by hours, and you select the Full Spread option. This configuration is (90 days * 24 hours ) = 2160 columns that the chart renders. You can limit the range or deselect the Full Spread option if you experience performance issues.
