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 Activity Instances 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 Activity Instances 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 and 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 a workflow contains many activities, it is recommended to set the Label Angle in the Properties section of the control to ensure that labels are displayed properly and do not overlap   
• The value of the Activity Instances Chart is the fully qualified name of the activity on the x-axis. When clicking on a bar, pie slice or column (depending on the type of Chart used) in runtime, the value of the Chart will be the name of the activity clicked and can subsequently be used to bind properties or configure rules
• 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
• 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 properties are available as Input Mapping properties and in the Context Browser when using rules for mapping to other controls. These properties are additional to those mentioned in the Properties section of this topic, but are only available for interaction with rules:
  Workflow Instance ID -  Can be used to filter the Activity Instances Chart down to a specified Workflow Instance ID
  Activity Display -  The Activity Name of the selected Activity. The name is displayed without the Folder and Process Name 
  
• When clicking for example the bar, pie slice or column of an Activity Instance Chart, the activity representing that bar can be used to populate a User Performance  Chart. The following rule can be configured to effect this in runtime:
  Event: When a control on the View raises an event
  Action: Execute a control's method
  Configuration: Map the Activity Instances Chart to the Activity Name filter of the User Performance Chart
  
  

The Activity Instances Chart control is available in the Reports section of the Controls found in the View Designer.
