Axis values not getting displayed in ASP.NET Chart control

I am using asp.net charts in my application, i have given the axis values from code behind. I added the on page load but the problem when i go directly to that page the graph will not appeare but if i reload the same page it will appeare. this happens when i publish the application and try on IIS, but there is no problem before publish (while run in VS).

What should i do to resolve this error..??
