ASP.net chart control: hide all lines (axes, etc.) except data points

问题

I'm trying to generate sparklines for a dashboard using the Microsoft chart control on ASP.net. Sparklines generally have no axes or anything other than the data points showing.

I've succesfully turned off most of the lines but I'm stuck with one horizontal and one vertical line I can't figure out how to get rid of. Here's what I see:

Here's what I want:

Here's an excerpt of the code I'm using (minus the actual data):

Chart2.Width = 100;
Chart2.Height = 60;
Chart2.BorderlineWidth = 0;

var name = "Northeast Region";
ChartArea area = new ChartArea(name);
area.AxisX.LabelStyle.Enabled = false;
area.AxisY.LabelStyle.Enabled = false;
area.AxisX.MajorGrid.Enabled = false;
area.AxisY.MajorGrid.Enabled = false;
area.AxisY.MajorTickMark.Enabled = false;
area.AxisY.MinorTickMark.Enabled = false;
area.AxisX.MajorTickMark.Enabled = false;
area.AxisX.MinorTickMark.Enabled = false;
area.BorderWidth = 0;

Chart2.ChartAreas.Add(area);
Series s = new Series(area.Name);
s.ChartType = SeriesChartType.Line;
s.ChartArea = area.Name;
s.Color = System.Drawing.Color.Gray;
foreach (var row in Data)
{
    s.Points.AddXY(row.StartDate, row.Sales);
}
Chart2.Series.Add(s);

Any ideas what I'm doing wrong?

Duh. I googled every possible combination of "hide" and "axis" and "line" but didn't Google "asp.net chart control sparklines" until after I posted this.

I was missing setting the LineWidth property on the ChartArea:

area.AxisX.LineWidth = 0;
area.AxisY.LineWidth = 0;

chart1.ChartAreas[0].AxisY.StripLines.Add(new StripLine()); 
chart1.ChartAreas[0].AxisY.StripLines[0].BackColor = Color.FromArgb(80, 252, 180, 65); 
chart1.ChartAreas[0].AxisY.StripLines[0].StripWidth = 40; 
chart1.ChartAreas[0].AxisY.StripLines[0].Interval = 10000; 
chart1.ChartAreas[0].AxisY.StripLines[0].IntervalOffset = 20;
