AxisY.ConvertPhysicalUnitsToData returns negative value when AxisY is collapsed

[Ramya]

((ChartArea)(sender)).AxisY.ConvertPhysicalUnitsToData(e.MouseData.GetPosition(SetElementType(e.OriginalSource)).Y) is returning unbelievable negative values when the AxisY visibility is collapsed. Is this a bug????

Hi Ramya,

When the Axis is collapsed it doesn't participate in the layout cycle of WPF. This means that it doesn't measure itself and thus the axis doesn't know how long or wide it is. When you call this method it uses some default values ant this explains the strange results you are getting. If you need this method consider making the axis visible at least at startup (so that it can measure).

All the best,
