replace a chart.serie with new values

Question

Is it possible to empty 1 serie in a chart that is constantly being built up with the help of a timer and fill it with 1 value? So that a straight line is put in the chart for this series.
So i want to update the Yvalue of a chart.serie. I found that i can read the Yvalues of a serie, but i do not know how to update them.
(I use c# winforms)

Check if this code meets expectations:

var points = chart1.Series[0].Points;

for( var i = 0; i < points.Count; ++i )
{
    points[i].YValues[0] = 1;
}

chart1.Invalidate( );

or

foreach( var p in chart1.Series[0].Points )
{
    p.YValues[0] = 1;
}

chart1.Invalidate( );
