that code didnt work but it gave me what i needed to find it. It was very close here is it is
chart1.AxisY.Style = chart1.AxisY.Style ^ SoftwareFX.ChartFX.
AxisStyle.BreakZero;
this removes the Mysterious Y axis zero line
Thanks a Million CarlosAc I searched high and low in the chart properties for many hours trying to remove this unwanted line.
