SharePoint 2013 & SQL Server Reporting Services

Question

Hi there,
We are developing a web application in sharepoint 2013 in which we are using authentication mode="Windows”.  We have used a custom web part containing report viewer control for showing charts and reports, that we have
developed using SSRS ( *.rdl files) and have all the .rdl files within Sharepoint Document Library.
To start with, we were getting the error “Report Server has encountered a SharePoint error. (rsSharePointError) The user does not exist or is not unique.” To fix this, we changed <identity impersonate="false"
/> from <identity impersonate="true" /> at web.config level which did the trick.
However, we are now facing another issue wherein tabular reports are renedered ok in SharePoint through report viewer custom web part but chart based reports are not rendered. The chart image is not displayed.  
Can somebody please help with a resolution?
The code snippet for rendering the report is given below for reference purposes
Thanks in advance
Monica

+ ReportPath;
            litReportHeading.Text = ReportPath;
            reportViewerControl.ServerReport.ReportPath = reportFullPath;
            reportViewerControl.ServerReport.ReportServerUrl =
new
Uri("http://c4968397007/_vti_bin/ReportServer");
            reportViewerControl.ProcessingMode = Microsoft.Reporting.WebForms.ProcessingMode.Remote;
            Microsoft.Reporting.WebForms.ServerReport
serverreport = reportViewerControl.ServerReport;
IReportServerCredentials irsc =
new
ReportViewerCredentials("username",
"password",
"domainName");
            rvControl.ServerReport.ReportServerCredentials = irsc;
            rvControl.ServerReport.Refresh();
