Generate your chart first then pass the chart to your new form. The chart created will be the same size as your form.

VB

'Create form
Dim MyForm As New Form
'Create chart
Dim Chart1 As New Chart
  'Add series and format the chart
  Chart1.ChartAreas.Add("Area51")
  Chart1.Series.Add("Speed")
  Chart1.Series("Speed").ChartType = SeriesChartType.Bar

  'Populate the chart data (Remember that X and Y need to be numbers, No Strings)
  For Each line As String In IO.File.ReadAllLines("C:\FolderWithData\MyData.csv")
    Dim points() As Double = Array.ConvertAll(line.Split(","c), Function(s) CDbl(s))
    Chart01.Series("Speed").Points.AddXY(points(1), points(0))
  Next

  'Add chart to the new form and disdplay it
  MyForm.Controls.Add(Chart01)
  MyForm.Show()

This will not work you can not use strings in Points.AddXY, only numbers, like X and Y coordinates. You need to add labels to your data to put the names in.

VB

this.chart1.Series["Speed"].Points.AddXY("James", "90"); NO!

chart1.Series["Speed"].Points.AddXY(0, 90);
chart1.Series["Speed"].Points.AddXY(1, 18);
chart1.Series["Speed"].Points.AddXY(2, 83);

Good luck
