Security is applied to the controls to ensure that the data is seen by authorized individuals within an organization. Permissions are based on the process rights assigned to the process in Management Console:

• Users with Admin or View permissions will have access to the Report controls.
• Users with View Participate permissions will be permitted to view the Report controls from the point where the user has been part of the workflow.

1. Create a View
2. Drag the Workflow Duration Chart control onto the canvas. The control can be found in the Reports section of the Controls found in the View Designer, see the Properties section below 
3. Configure the properties of the Workflow Duration Chart control as required, see the Properties section below 
4. Add a rule to Run the Chart when the View is Initialized for example:
   Event: When a control on the View raises an event (When the View is Initialized)
   Action: Execute a control's method (Execute the Run Chart method)
   

• Always remember to create a rule to Run the Chart when the View Initializes
• When using a percentage for the width of the control and used in conjunction with the Save as PDF control, a pixel width is calculated and applied to the control’s width thus making the width of the Chart pixel based rather than percentage based. It is therefore advised to use a non-percentage based width when using the Chart with the Save as PDF control
• A Workflow name(s) needs to be mapped to the Workflow Duration Chart in order to populate the chart
• When using Custom Themes, be sure to specify the CSS classes for the elements
• The data of K2 workflows or processes created by any workflow designer such as K2 Studio, K2 Designer for Visual Studio, K2 Designer and K2 Designer for SharePoint  can be made available using the reporting controls 
• When using a percentage for the width of Chart controls and used in conjunction with the Save as PDF control, a pixel width is calculated and applied to the control’s width thus making the width of the Chart pixel based rather than percentage based. It is therefore advised to use a non-percentage based width when using a Chart with the Save as PDF control 

Report controls interact with each other through rules. By binding properties between different controls, data can be used to populate properties or set values in runtime.

• The following property is available in the Context Browser when using rules for mapping to other controls. This property is additional to those mentioned in the Properties section of this topic,  but is only available for interaction with rules:
  Selected Range - The range of the selected column. This property returns the start and end dates to be passed into other controls
  
• A rule can be created to open the Workflow Duration Grid when clicking on a record in a  Workflow Instances Chart. The rule will look like this:
  Event: When a control on the View raises an event
  Action: Execute a control's method
  Configuration: Map the Workflow Names filter of the Workflow Instances Chart to the Workflow Names filter of the Workflow Duration Chart
  
  

The Workflow Duration Chart control is available in the Reports section of the Controls found in the View Designer.
