Hi Sebastien,
We regret very much for the delayed response. It is possible hide the line at the empty points by setting the IsEmpty property to true for the particualr ChartPoint.
Sample Code: if (this.chartControl1.Series[0].Points[i].YValues[0] == 0)
{
this.chartControl1.Series[0].Points[i].IsEmpty = true;
}
I have attached the sample that illustrates the same in this link below.
