I've eliminated all the mvc html helpers from my code and generated the chart at client side, javascript. Since then, it doesn't show up any series in ie, firefox or even safari with webkit.
However, everything works fine in google chrome! Can you please help me?

Sorry, my fault. I used the new Date() to create values for the categorydatetimex with a string format that was good for chrome only.
yep, I've done that one before too ;-)
