Thank you very much!

I changed the axisX to this:

 axisX:{
            intervalType: "minute",
            xValueType : "dateTime",
            valueFormatString: "HH:mm" ,
            labelAngle: -50
        },

And I can see the graph now!

small question… in my x ax, I see HH:mm instead of the values. also standing on a point will show the timestamp as 34200000 for example…
How did you set the axisX to show it correctly?

Thanks a lot!!!
