Multiple dynamic lines in chart

Hi all,

I want to create a linechart with a dynamical number of lines. Is there an example online? Any good practices?

The general idea is:

grid.onrow(s)select => getdata => add to chart

In somewhat more detail:

Code:

(grid multiselect)

chart.series.remove();

store.load({
      params: { (multiselect)
      }, 
       callback: function(xxxxx) {
               each(row) {
                    var serie = {
                             type: 'line',
                              data  = data
                          };
                    chart.add(serie);
               }
      }
}

chart.redraw();

Is this a sensible way to solve this?

Any comments or suggestions appreciated.
