vb.net setting the scale to a chart to maximum

Question

I have a line chart in VB using the standard WinForm Chart control (System.Windows.Forms.DataVisualization.Charting.Chart). On the Y axis is the amount of cars, on the X axis is the time. Each point is submitted every hour. it looks like this:

As you can see the time (X-axis) is displaying correctly, it shows 1 then 2 then 3 and so on.. but as the chart gets bigger it starts removing the grid on the x values, as well as their labels, like so:

Please can someone inform me as to how I can prevent the graph from automatically removing the x values label.

Thank you, and I have not provided code because I have tried everything and none of it seems to work. I have a feeling its somewhere in the properties for the graph.

EDIT:

Here is the code that I use to generate the chart.

Dim lightvehicleaveragetime As New Series
lightvehicleaveragetime.Name = "Light Vehicle"
lightvehicleaveragetime.ChartType = SeriesChartType.Spline
Form3.Chart1.Series.Add(lightvehicleaveragetime
lightvehicleaveragetime.IsValueShownAsLabel = True
lightvehicleaveragetime.BorderWidth = 3

The rest of the code runs in a while loop, and everytime the hour changes, it will add:

lightvehicleaveragetime.Points.AddXY(hour & ":" & minute & ":" & seconds, alllightvehicleentriesgraphtime)
lightvehicleaveragetime.LabelToolTip = time
lightvehicleaveragetime.MarkerStyle = MarkerStyle.Circle
lightvehicleaveragetime.MarkerSize = 5
lightvehicleaveragetime.MarkerColor = Color.Black

Answer 1

It seems as if you need to restrict the x axis values to be hours. the interval type or minor/major grids might help. Have you tried

  Chart1.ChartAreas(0).AxisX.IntervalType = DateTimeIntervalType.Hours

and try setting

  Chart1.ChartAreas(0).AxisX.Interval = 1
