Answer 1

var xAxis = yourChartObject
            .ActualAxes
            .OfType<LinearAxis>()
            .FirstOrDefault(ax =>   ax.Orientation == AxisOrientation.X);
if (xAxis != null)
{
    xAxis.Maximum -= (points you want to move);
    xAxis.Minimum -= (points you want to move);
}

UPDATE:

I haven’t used it anytime but here is some thing. If you have datetime on X-axis most of the charts convert datetime into double value using ToOADate method. If that is the case with your chart as well first convert the value back to datetime then AddMinutes

This is how you do that

xAxis.Maximum = DateTime.FromOADate(xAxis.Maximum).AddMinutes(mintuestoadd);
