WinForms: highlighting X and Y axes

Question

I'm making a program to graph parabolas, and I want to make the X and Y axes (the ones from (0,0)) a different color. I haven't found any options to do so, and the only solution I've found is to make a large grid and set its increment to half the graph's size. Is there an alternative?

I used the default chart control. I'd expect something like:

You can set Crossing for axis to move the axis to center of chart. Also you can set LineWidth for axis to make it thicker. Also you can set ArrowStyle to have an arrow at the end of axis.

For example, to have a chart like this:

Use such code:

private void Form1_Load(object sender, EventArgs e)
{
    //Set Chart Margins
    this.chart1.ChartAreas[0].Position.Auto = false;
    this.chart1.ChartAreas[0].Position.X = 10;
    this.chart1.ChartAreas[0].Position.Y = 10;
    this.chart1.ChartAreas[0].Position.Width = 80;
    this.chart1.ChartAreas[0].Position.Height = 80;

    //Configure X Axis
    this.chart1.ChartAreas[0].AxisX.Crossing = 0;
    this.chart1.ChartAreas[0].AxisX.Interval = 1;
    this.chart1.ChartAreas[0].AxisX.LabelStyle.Enabled = false;
    this.chart1.ChartAreas[0].AxisX.LineWidth = 2;
    this.chart1.ChartAreas[0].AxisX.ArrowStyle =
        System.Windows.Forms.DataVisualization.Charting.AxisArrowStyle.Lines;

    //Configure Y Axis
    this.chart1.ChartAreas[0].AxisY.Crossing = 0;
    this.chart1.ChartAreas[0].AxisY.Interval = 5;
    this.chart1.ChartAreas[0].AxisY.LineWidth = 2;
    this.chart1.ChartAreas[0].AxisY.LabelStyle.Enabled = false;
    this.chart1.ChartAreas[0].AxisY.ArrowStyle =
        System.Windows.Forms.DataVisualization.Charting.AxisArrowStyle.Lines;

    //Set Chart Type
    this.chart1.Series[0].ChartType = 
        System.Windows.Forms.DataVisualization.Charting.SeriesChartType.Spline;

    //Set Data
    var p = new List<PointF>();
    for (int i = -5; i <= 5; i++)
    {
        p.Add(new PointF(i, i * Math.Abs(i)));
    }
    this.chart1.DataSource = p;
    this.chart1.Series[0].XValueMember = "X";
    this.chart1.Series[0].YValueMembers = "Y";
    this.chart1.Series[0].IsVisibleInLegend = false;
}
