i’m new to Chart Control so i need some help

i have declared and created a new series in a event lets say FormLoad event. i want to use the same series to be used in an other event how can i do it

eg:

public void Form1_Load(object sender, EventArgs e)
        {
            Series Series1 = new Series();
            Series1.Name = "Series#";
            Series1.ChartArea = "ChartArea1″;
.
.
.

             Series1.Points.AddXY(varX, varY);  
.
.
.
               Chart1.Series.Add(Series1);
         }

i want this Series1 to be available even in other events(like some public variable) how do i do it please help
