why pie chart is showing value for only one field? - asp.net

Question

I am trying to use a pie chart and I expect 2 regions get displayed on it. But for my following code, only the last one is shown.
Code behind:
protected void Page_Load(object sender, EventArgs e)
{
DataTable dt = new DataTable();
dt.Columns.Add("status");
dt.Columns.Add("count");
DataRow dr = dt.NewRow();
dr["status"] = "safe";
dr["count"] = loadChart("safe");
dt.Rows.Add(dr);
dr["status"] = "unsafe";
dr["count"] = loadChart("unsafe");
dr = dt.NewRow();
dt.Rows.Add(dr);
Chart1.DataSource = dt;
Chart1.Series[0].XValueMember = "status";
Chart1.Series[0].YValueMembers = "count";
Chart1.DataBind();
}
Mark up:
<asp:Chart ID="Chart1" runat="server">
<series>
<asp:Series ChartType="Pie" Name="Series1">
</asp:Series>
</series>
<chartareas>
<asp:ChartArea Name="ChartArea1">
</asp:ChartArea>
</chartareas>
</asp:Chart>
output:
I want to see the safe portion also. I have value for it.how to resolve this issue ?

Answer 1

You are setting values in the same row twice:
DataRow dr = dt.NewRow();
dr["status"] = "safe";
dr["count"] = loadChart("safe");
dt.Rows.Add(dr);
//still in the same row
dr["status"] = "unsafe";
dr["count"] = loadChart("unsafe");
dr = dt.NewRow();
dt.Rows.Add(dr);
you should create new row and then set second values:
DataRow dr = dt.NewRow();
dr["status"] = "safe";
dr["count"] = loadChart("safe");
dt.Rows.Add(dr);
//new row creation
dr = dt.NewRow();
dr["status"] = "unsafe";
dr["count"] = loadChart("unsafe");
dt.Rows.Add(dr);
