What I have tried:

C#

<pre>void Page_Load(Object sender, EventArgs e)
        {   
            Chart.TitleBox.Label.Text = "Student Progress";
            Chart.Width = 750;
            Chart.Height = 550;
            SeriesCollection mySC = Calculate();
            Chart.XAxis.Label.Text = "Marks";
            Chart.YAxis.Label.Text = "No of Students";
            Chart.SeriesCollection.Add(Calculate());
           
        }

        SeriesCollection Calculate()
        {
            SeriesCollection SC = new SeriesCollection();
            Random myR = new Random(1);
            for (int a = 0; a < 4; a++)
            {
                Series s = new Series();
                s.Name = "Series " + a.ToString();
                for (int b = 1; b < 5; b++)
                {
                    Element e = new Element();
                    e.Name = "Element " + b.ToString();
                    e.YValue = myR.Next(50);
                    s.Elements.Add(e);
                }
                SC.Add(s);
            } 
            SC[0].Element.Color = Color.FromArgb(49, 255, 49);
            SC[0].Elements[0].Name = "English";
            SC[0].LegendEntry.Value = "13";
            SC[0].LegendEntry.Name = "10-15";
            
            SC[1].Element.Color = Color.FromArgb(255, 255, 0);
            SC[1].Elements[0].Name = "Maths";
            SC[1].LegendEntry.Value = "32";
            SC[1].LegendEntry.Name = "10-40";
            
            SC[2].Element.Color = Color.FromArgb(255, 99, 49);
            SC[2].Elements[0].Name = "Science";
            SC[2].LegendEntry.Value = "6";
            SC[2].LegendEntry.Name = "0-10";
            
            SC[3].Element.Color = Color.FromArgb(0, 156, 255);
            SC[3].Elements[0].Name = "Computer";
            SC[3].LegendEntry.Value = "18";
            SC[3].LegendEntry.Name = "15-30";
            return SC;
        }

Solution 1

Your question is a bit vague... I'll take a stab at it though...

C#

while (chart1.Series.Count > 0) { chart1.Series.RemoveAt(0); }

Hi Graeme
Thanks for your reply.I am using
Chart.SeriesCollection.Add(Calculate()); but it show my chart as well as Chart.DefaultSeries..... in the output

Graeme_Grant 2-Mar-17 6:44am

Did you try using it before loading your data?

Member 12605293 2-Mar-17 6:49am

Int the above snippet ,which has the datas From which I am getting the default one

Graeme_Grant 2-Mar-17 6:50am

I meant, did you try my code before you run yours to remove the default/any series?

Graeme_Grant 2-Mar-17 23:03pm

How did you go?

Member 12605293 3-Mar-17 0:02am

Yes sir thanks for your reply.Now I am getting another namespace issue,while putting code in .cs

This is my code and I require the relavent namespaces sir

protected void Page_Load(object sender, EventArgs e)
{
Chart.TitleBox.Label.Text = "Student Progress";
Chart.Width = 750;
Chart.Height = 550;
SeriesCollection mySC = Calculate();
Chart.XAxis.Label.Text = "Marks";
Chart.YAxis.Label.Text = "No of Students";
Chart.SeriesCollection.Add(Calculate());
Chart.DefaultSeries.DefaultElement.URL = "JavaScript: myAlert(\'Clicked on element %Name in series %SeriesName \')";
Chart.TitleBox.Position = TitleBoxPosition.Full;
Chart.TitleBox.Label.Font = new Font("TimesRoman", 10, FontStyle.Bold | FontStyle.Italic);
Chart.TitleBox.Label.Alignment = StringAlignment.Center;
Chart.TitleBox.Label.Color = Color.DarkBlue;
Chart.TitleBox.Background.Color = Color.FromArgb(225, 122, 212);
Chart.TitleBox.Padding = 7;
Chart.LegendBox.DefaultEntry.LabelStyle.Font = new Font("Arial", 10, FontStyle.Italic);
Chart.LegendBox.Line.Color = Color.FromArgb(56, 66, 177);
Chart.LegendBox.Line.Width = 2;
Chart.LegendBox.Background = new Background(Color.FromArgb(165, 174, 255), Color.FromArgb(233, 235, 240), 45);
Chart.LegendBox.Orientation = dotnetCHARTING.Orientation.Bottom;
}
SeriesCollection Calculate()
{
SeriesCollection SC = new SeriesCollection();
Random myR = new Random(1);
for (int a = 0; a < 4; a++)
{
Series s = new Series();
s.Name = "Series " + a.ToString();
for (int b = 0; b < 1; b++)
{
Element e = new Element();
e.Name = "Element " + b.ToString();
e.YValue = myR.Next(50);
s.Elements.Add(e);
}

SC.Add(s);
}
SC[0].Element.Color = Color.FromArgb(49, 255, 49);
SC[0].Elements[0].Name = "English";
SC[0].LegendEntry.Value = "13";
SC[0].LegendEntry.Name = "Between 10-15";

SC[1].Element.Color = Color.FromArgb(255, 255, 0);
SC[1].Elements[0].Name = "Maths";
SC[1].LegendEntry.Value = "32";
SC[1].LegendEntry.Name = "Between 10-40";

SC[2].Element.Color = Color.FromArgb(255, 99, 49);
SC[2].Elements[0].Name = "Science";
SC[2].LegendEntry.Value = "6";
SC[2].LegendEntry.Name = "Between 0-10";

SC[3].Element.Color = Color.FromArgb(0, 156, 255);
SC[3].Elements[0].Name = "Computer";
SC[3].LegendEntry.Value = "18";
SC[3].LegendEntry.Name = "Between 15-30";
return SC;
}

Please don't post code in the reply area. It loses formatting and makes readability difficult. The question area is the best place for it.

If the problem is different, start a new question and give specific details of what you are doing, code with the problem (including any other relevant code associated with the problem), any errors (including inner error messages), and how you are stuck. This will make it much easier for everyone.

Thanks sir I'l do:)
