iis - ASP.NET MVC3 Chart Web helper doesnt work when hosted on IIS7 -

-

i'm using new chart helper method available in system.web.helpers assembly shown here

http://www.dotnetcurry.com/(x(1)s(jm1obicbiav03qq3dnxug2ap))/showarticle.aspx?id=597&aspxautodetectcookiesupport=1

it works fine when run app in visual studio's inbuilt server. when publish website virtual directory in iis on local machine, image doesnt show , in place "red cross" mark shows up.

i'm not using relative paths , static content available on server since can see other images displayed in app when published.

here's view

{img src="/home/getrainfallchart" alt="chart" /}

this action

    public actionresult getrainfallchart()     {          var key = new chart(width: 600, height: 400).addseries(                                charttype: "area",                                legend: "rainfall",                                xvalue: new[] { "jan", "feb", "mar", "apr", "may" },                                yvalues: new[] { "20", "20", "40", "10", "10" })                                .write();         return null;     }

do need copy dlls when publishing?

found solution

need work on iis when hosted on virtual directory

<img src = <%= url.content("~/home/getrainfallchart") %>" alt="chart" />
