Two series with different number of values.

[Sonia]

I want to use RadChart to show the evolution of an indicator value compared to an objective value along a configurable period.

A database query returns the list of values, however maybe there is no values for all the periods.

01/01/2013 47,32
01/02/2013 35,36
01/03/2013 60,53
01/04/2013 82,75

I made the DataBind from a SqlDataReader.

On the other hand i know the objective value at the begining of the period and at the end of the period, for example:

01/01/2013 20           //This is the objective value in the first period
01/12/2013 120 //This is the objective value in the last period

ChartSeries serieObjective = new ChartSeries("Objective") { Type = ChartSeriesType.Line };
serieObjective.Items.Add(new ChartSeriesItem(1, 20));


int periods = NumberOfPeriods(firstPeriod, lastPeriod);  //Returns the number of periods (in this example 12)
serieObjective.Items.Add(new ChartSeriesItem(periods, 120));
chart.Series.Add(serieObjective);


In my chart I only can see the first 4 periods as the first serie only has 4 values.
Therefore I cannot see the value of the second serie at the end of the period.

Any suggestion.
Thank you in advance.

Please help.
Anybody knows how to achieve that?

Hello Sonia,

I am not quite sure I understand your scenario completely. That is why, in case the information below does not help you, please open a new support ticket and send me a simple running project, demonstrating the problem that you have.

I created a simple test page to test your scenario but I was unable to reproduce the problem with the second line series not being fully visible. Here is the code of my test page for your reference:

<telerik:RadChart ID="RadChart1" runat="server">
</telerik:RadChart>

ChartSeries serieIndicator = new ChartSeries("Indicator") { Type = ChartSeriesType.Line };

serieIndicator.Items.Add(new ChartSeriesItem(1, 47));
serieIndicator.Items.Add(new ChartSeriesItem(2, 35));
serieIndicator.Items.Add(new ChartSeriesItem(3, 60));
serieIndicator.Items.Add(new ChartSeriesItem(4, 82));
RadChart1.Series.Add(serieIndicator);

ChartSeries serieObjective = new ChartSeries("Objective") { Type = ChartSeriesType.Line };

serieObjective.Items.Add(new ChartSeriesItem(1, 20));
serieObjective.Items.Add(new ChartSeriesItem(12, 120));
RadChart1.Series.Add(serieObjective);

You can review our online demos and documentation for additional information on RadChart for ASP.NET
AJAX.

All the best,

Thank you Tsvetie. Your sample has helped me to find the problem.
