I am tryting to develop a chart in Highstock where each marker got an individual color. When i push my Data in an Array like this :

      series.data.push([ 
       parseInt(Math.round(myDate.getTime())),
       parseInt(Math.round(myDate.getHours()))
       ]);

The Data is shown correctly, but when i try to set the color within each data-object like this, it doesn't work to show points.

          series.data.push([ {          
          x:   parseInt(Math.round(myDate.getTime())),
          y:   parseInt(Math.round(myDate.getHours())),
          marker:{fillColor: 'red'}} ]);

What am i missing?

Update: When i inspect it with firebug i can see that the series is set correctly within the chart object. so why does it now show up? :/
