I need to create a chart, preferably using MS Chart Controls, that looks like a stepline chart with the exception that color has to be filled in under the line. An area chart won't block off values like a stepline chart (it creates a direct, or curved, line from one point to another). An area chart does fill in the color the way I would like it to be but I want a stepline effect. What I guess I want is a StepArea chart. I would imagine that it should be possible but I haven't been able to configure it the way I want. how I can do this?

C#:
protected void Page_Load(object sender, EventArgs e) {
if (!IsPostBack) {
LineGraphFunction();
}
}
//code for line graph
protected void LineGraphFunction()
[code]....
HTML:
<cc1:LineChart ID="LineChart1" Width="500px" runat="server" ChartHeight="300" ChartWidth = "450" TooltipBorderColor="#D8D8D8" TooltipFontColor="blue"
ChartType="Basic" ChartTitleColor="#0E426C" Visible = "false" BorderColor="Blue" BorderWidth="1px"
CategoryAxisLineColor="#D08AD9" ValueAxisLineColor="#D08AD9" BaseLineColor="#A156AB">
</cc1:LineChart>
Problem is:
In the "LineChart", everytime last "y-axis" point is going out of graph (i.e., somewhere in the footer of x-axis)
X-axis Y-axis
3.4 5.2
5.3 7
2 8.7
1) like in above table, all the point will plot except the last x-axis and y-axis points. Also, y-axis value = 8.7 goes away from graph and comes in the footer of x-axis line.
2) like if x-axis = 3, y-axis=6, then 6 goes out of the graph and comes in footer of x-axis line.
But this problem occurs only when Im using SELECT query for a "particular Id" i.e.,
SELECT x,y from Table1 where Id='Gaug9' and DeletionDate is null
If I will remove where Id=' ' then it will work fine. But I need to plot graph based on particular Id's.

This is my aspx code :
<asp:Chart ID="ChartAlertes" runat="server" Width="500px">
<Titles>
<asp:Title Text="Nombre d'alertes et leurs status en fonction des filtres renseignés"
BorderColor="Black" Alignment="TopCenter">
</asp:Title>
</Titles>
[code]...
I display 2 Points (2 columns) in the Chart Control and I change the color of the each Points with :
ChartAlertes.Series[0].Points[0].Color = System. Drawing. Color.Red;ChartAlertes.Series[0].Points[1].Color = System.Drawing.Color.DarkOrange;
But sometimes, I have only 1 Point to display or nothing at all on the Chart. So I'd like to check If there are some Points before to put the color of each Point.
For example :
if (ChartAlertes.Series[0].Empty == false)
{
//...
}

I work with a tank of visual studio when I click to display the graph he shows not all points on the X axis
for example the table nbr_num_semaine_av contains values in order
(18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,1,2,3,4)
but the graph shows on the X axis only that 18, 38, 41
for (int k = 0; k < semaine.Count(); k++) {
Chart4.Series["Nombre de points terminés"].Points.AddXY(nbr_num_semaine_av[k], nbr_points_Termin[k]);
Chart4.Series["Nombre Total d'element"].Points.AddXY(nbr_num_semaine_av[k], nbr_element.Count());
}
Chart4.Series["Nombre de points terminés"].ChartType = SeriesChartType.Line;
Chart4.Series["Nombre Total d'element"].ChartType = SeriesChartType.Line;
Chart4.Series["Nombre de points terminés"].IsXValueIndexed = true;
Chart4.Visible = true;

I have a graph created with MS Chart like the following picture. As you can see the vertical lines are messed up with value of the top of each bar. Here's the mark-up for the graph:
<asp:Chart ID="chtNBAChampionships" runat="server">
<Series>
<asp:Series Name="Championships" YValueType="Int32" ChartType="Column" ChartArea="MainChartArea" IsValueShownAsLabel="true">
<Points>
<asp:DataPoint AxisLabel="Celtics" YValues="17" />
<asp:DataPoint AxisLabel="Lakers" YValues="15" />
<asp:DataPoint AxisLabel="Bulls" YValues="6" />
<asp:DataPoint AxisLabel="Spurs" YValues="4" />
<asp:DataPoint AxisLabel="76ers" YValues="3" />
<asp:DataPoint AxisLabel="Pistons" YValues="3" />
<asp:DataPoint AxisLabel="Warriors" YValues="3" />
</Points>
</asp:Series>
</Series>
<ChartAreas>
<asp:ChartArea Name="MainChartArea">
</asp:ChartArea>
</ChartAreas>
</asp:Chart>
I don't want the display the vertical line because it's messed up with the value on top of the each bar. How can I disable the vertical line?
