ZED Graph dynamically y max value change

hello everyone

i need some help in plotting a graph in my application first i tell you what am i doing...

here

myPane.YAxis.Scale.Min = 0;
myPane.YAxis.Scale.Max = 100;


 if (myCurve_1.Points.Count > 250)
 {
     myPane_1.XAxis.Scale.Min = myPane_1.XAxis.Scale.Min + 1;
 }
 if (y > myPane_1.YAxis.Scale.Max)
 {
     myPane_1.YAxis.Scale.Max = y;
 }

 if (y < myPane_1.YAxis.Scale.Min)
 {
     myPane_1.YAxis.Scale.Min = y;
 }
 x_1 = x_1 + 1;
 zgc.AxisChange();

according to my code it will change y axis scale max value if y is greater then max value so it increases the scale but when that high value peak passed it did not change the max value... actually i have no logic to plot it like for example i have utorrent in which graph scale is changing according to the max value but it remains same when high value curve is in the graph when it passed away it changes the scale according to next high value.

kindly help me creating a logic also tell me how would i know through coding that high curve is passed.

Thanx
