Hello dbishop9,

You can view our online samples here.

The sample in particular that might interest you is the scatter line chart sample.

You can view the code by clicking on the "Source Code" tab at the top.

The documentation on the Scatter Line chart can be found in our online help.

If you would like more help with this, I can forward your post to Developer Support, and they can provide assistance with setting up a sample.

Here is a sample that shows how to set Annotations in the .aspx file.

You can also view the documentation on annotations.

Let me know if there's anything else!

Here is a sample about how to display data point labels.  The page load event has some code for showing the labels. It sets the this.UltraChart1.ScatterChart.ChartText[0].Visible property.

I found this API page for the ChartText property.

Please look at the sample and its code and see if that works.  That data point label implementation might be specific to the sample.  If it is not useful, I can forward your post to developer support, and they can open a case for you.

Here is the link that will give you more details on dynamically creating ChartText Collection and setting properties:
 
<http://help.infragistics.com/NetAdvantage/ASPNET/2010.2/?page=Chart_Apply_Chart_Text_Labels.html>

Refer to the code on above link. You can add ChartText to other types of chart also.

Please let me know if you have any further questions with this matter.

Thanks,

I followed the "getting started" topic in the help to come up with this code behind for creating the data (just as an example).

        protected void Page_Load(object sender, EventArgs e)
        {
            this.UltraChart1.DataSource = GetColumnData();
            this.UltraChart1.DataBind();
        }

        private DataTable GetColumnData()
        {
            DataTable mydata = new DataTable();

            mydata.Columns.Add("Series Labels", typeof(string));
            mydata.Columns.Add("XValue", typeof(int));
            mydata.Columns.Add("YValue", typeof(int));

            mydata.Rows.Add(new Object[] { "Mercury", 5, 20 });
            mydata.Rows.Add(new Object[] { "Venus", 10, 20 });
            mydata.Rows.Add(new Object[] { "Earth", 15, 20 });
            mydata.Rows.Add(new Object[] { "Mars", 20, 20 });

            return mydata;
        }

Then I did what Swetha suggested.  I set the Column value differently each time, but I'm not sure that it matters.  Setting the Visible property on each item might be the key.  Here's how it appeared in the .aspx page.

            <ChartText>
                <igchartprop:ChartTextAppearance ChartTextFont="Arial, 7pt" Column="0"
                    ItemFormatString="Mercury" Row="0" Visible="True" />
                <igchartprop:ChartTextAppearance ChartTextFont="Arial, 7pt" Column="10"
                    ItemFormatString="Venus" Row="1" Visible="True" />
                <igchartprop:ChartTextAppearance ChartTextFont="Arial, 7pt" Column="15"
                    ItemFormatString="Earth" Row="2" Visible="True" />
                <igchartprop:ChartTextAppearance ChartTextFont="Arial, 7pt" Column="20"
                    ItemFormatString="Mars" Row="3" Visible="True" />
            </ChartText>

I hope that information helps you with setting it in the code behind.

I have attached a screenshot.  I can upload my sample project if you'd like, but I simply explored the designer and property windows.
