Hi Thanks a lot for your answer, however it is not exactly what I want . I would like to have every point linked. Which mean that for the example you gave one should not see gap between 09/03/2012 and 12/03/2012 and between 16/03/2012 and 19/03/2012.

Do you know how one can do that ?

Thanks

Hi,

I just tried it bu it does not work because the null is replaced by a 0 , whcih is invisible to .NullHandling .

So, in such kind scenario ( where we are not able to set Null values ), my suggestion is to set 0 (zero) instead of Null. Also we will used option 2 with small modification to achieve desired behavior . Please take a look below at the new version of Option 2

ultraChart1.ChartType = ChartType.LineChart;
ultraChart1.Data.SwapRowsAndColumns = true;
ultraChart1.Axis.X.Extent = 120;
var a = from q in dt.AsEnumerable()
        where (double)q.ItemArray.GetValue(1) != 0
        select q;
ultraChart1.DataSource = a.AsDataView();

Let me know if you have any questions.

Regards

Hi,

The problem is that I am not filling my ultragrid with a datatable but with  a NumericTimeDataPoint. Moreover, it is not an ultrachart but a scatterchart.

Is option 2 is adaptable to this scenario ?

Thanks

Sorry, but I`m confused from your response.

 In my scenario I`m using DataTable as a datasource to our UltraChart. I`m not using UltraGrid.

Now, about the main task with the Points. I`m confuse why we should add a points (Saturday and Sunday ) to our Points collection. Just add one IF condition and exclude it (do not added this points to Points collection). 

Please let me know if you think that I misunderstood your scenario and questions.

Thanks, however, I have already removed Saturday and Friday that is the reason why you have spaces every 5 points on the graph I sent.

Thanks for provided code. My suggestion is to add IF condition and exclude the points for Saturday and Sunday. For example:

for (int i = 0; i < test.Rows.Count; i++)
{
    try
    {
        if (Convert.ToDateTime(test.Rows[i][0]).DayOfWeek != DayOfWeek.Saturday && Convert.ToDateTime(test.Rows[i][0]).DayOfWeek != DayOfWeek.Sunday)
        {
            InitNumeric.Points.Add(new NumericTimeDataPoint((DateTime)test.Rows[i][0], (double)test.Rows[i][9] * 100, "A", false));
        }
    }
    catch (InvalidCastException)
    {
        InitNumeric.Points.Add(new NumericTimeDataPoint((DateTime)test.Rows[i][0], Convert.ToDouble(null), "A", false));
    }
}  
 

Let me know if you have any questions.

Hi ,

this is my scenario :

        for (int i = 0; i < test.Rows.Count; i++)
                    {
                        try
                        {
                            InitNumeric.Points.Add(new NumericTimeDataPoint((DateTime)test.Rows[i][0], (double)test.Rows[i][9] * 100, "A", false));
                        }
                        catch (InvalidCastException)
                        {
                            InitNumeric.Points.Add(new NumericTimeDataPoint((DateTime)test.Rows[i][0],Convert.ToDouble(null), "A", false));
                        }
                                               
                    }

            for (int i = 0; i < test.Rows.Count; i++)
                    {
                        try
                        {
                            InitNumeric.Points.Add(new NumericTimeDataPoint((DateTime)test.Rows[i][0], (double)test.Rows[i][9] * 100, "A", false));

            ChartToStyle.TitleLeft.Margins.Bottom = -1;
            ChartToStyle.TitleLeft.HorizontalAlign = StringAlignment.Center;


        }

Maybe you should set this property:
ultraChart1.Axis.X.TimeAxisStyle.TimeAxisStyle = RulerGenre.Discrete;

Also, could you please upload your sample in this forum thread. I`ll be glad to research your scenario and I`ll try to find solution.
