I think you should convert the string date representation to an actual datetime object before adding it to the chart. I didn't test it but something like this: (where yourDate is the string you used to pass to the chart)

Dim format as String = "MM.dd.yyyy"
Dim actualDate as Date = Date.ParseExact(yourDate, format)
chart.Series(chart.Series.Count - 1).Points.AddXY(actualDate, 4.9)

The chart can manage datetime object instead of strings and it has special code that deals with dates. If you do this you you can adjust how it is displayed by formatting:

chart.ChartAreas(0).AxisX.LabelStyle.Format ="MM.dd.yyyy"
chart.ChartAreas(0).AxisX.Interval = 1
chart.ChartAreas(0).AxisX.IntervalType = DateTimeIntervalType.Days

If you wanted to only display every other day change the interval to 2
