Add chart to VF page

I am trying to add a chart to a VF page with a standard controller.  The only examples of VF page charts work with controllers so when I try to add my chart as a extension I get he following error.  'Unknown construction 'BurnReportPieChartController.BurnReportPieChartController(ApexPages.StandardController controller)'  how can I add a chart to my page?  My controller and page are below.

COntroller 
public class BurnReportPieChartController {
    
 public List<PieWedgeData> getPieData() 
    {  
        List<PieWedgeData> data = new List<PieWedgeData>();
        List<SFDC_Project__c> install = new List<SFDC_Project__c>();  
        
        String sql = 'SELECT id, Logged_Billable_Time_All_Roles__c, Remaining_All_Budgeted_Hours__c FROM SFDC_Project__c';
        install = Database.Query(sql);
        for(SFDC_Project__c temp:install)
        {           
            data.add(new PieWedgeData('Logged Billable Hours',temp.Logged_Billable_Time_All_Roles__c));
            data.add(new PieWedgeData('Remaining Billable Hours',temp.Logged_Billable_Time_All_Roles__c));
        }
        return data;  
    }  
    
    // Wrapper class  
    public class PieWedgeData 
    {  
        public String name { get; set; }  
        public Decimal data { get; set; }  
        
        public PieWedgeData(String name, Decimal data) 
        {  
            this.name = name;  
            this.data = data;  
        }

Hi,

The issue here is that you are using your Apex Class as an Extension to a Standard controller. However you dont have a constructor defined in your class which will take a standard controller for initialization (Extension Constructor). Adding such a constructor to your class will resolve the issue.

Your class should look something like this: 
public class BurnReportPieChartController {

private SFDC_Project__c project ;

 //This is the extension constructor
 public BurnReportPieChartController (ApexPages.StandardController stdController) { 
     this.project = (SFDC_Project__c)stdController.getRecord(); 
    } 
    
 public List<PieWedgeData> getPieData() 
    {  
        List<PieWedgeData> data = new List<PieWedgeData>();
        List<SFDC_Project__c> install = new List<SFDC_Project__c>();  
        
        String sql = 'SELECT id, Logged_Billable_Time_All_Roles__c, Remaining_All_Budgeted_Hours__c FROM SFDC_Project__c';
        install = Database.Query(sql);
        for(SFDC_Project__c temp:install)
        {           
            data.add(new PieWedgeData('Logged Billable Hours',temp.Logged_Billable_Time_All_Roles__c));
            data.add(new PieWedgeData('Remaining Billable Hours',temp.Logged_Billable_Time_All_Roles__c));
        }
        return data;  
    }  
    
    // Wrapper class  
    public class PieWedgeData 
    {  
        public String name { get; set; }  
        public Decimal data { get; set; }  
        
        public PieWedgeData(String name, Decimal data) 
        {  
            this.name = name;  
            this.data = data;  
        }  
    }  
}
Kindly mark as solved if this resolves your issue.
