    [CLOSED] Chart Line

    Hi,

    I'm with a problem in my chart, I'm not getting put the records the way like, not sure if it is possible, follows the records.

    Records:
    Date Description Percentage
    30/06/2012 With maturity 30 days 16.42
    30/06/2012 With maturity 60 days 28.28
    30/06/2012 With maturity 90 days 21.8
    30/06/2012 With maturity 180 days 33.5
    31/07/2012 With maturity 30 days 27.11
    31/07/2012 With maturity 60 days 20.95
    31/07/2012 With maturity 90 days 18.62
    31/07/2012 With maturity 180 days 33.32

    Chart Code:
    <ext:Chart ID="chtGrafico" runat="server" Animate="true" Width="800" 
        Height="500" Frame="true" Hidden="true" InsetPadding="30">

    I would like have two columns in CategoryAxis(30/06/2012, 31/07/2012) and in my right legend, I would like(With maturity 30 days, With maturity 60 days, With maturity 90 days, With maturity 180 days) refers to column Description(for each item would be a different line on the chart).

    Thanks.

    Hi,

    Could you provide a mockup to understand the requirement better?

    The following chart that I rode with the ideal result, see if you can understand, based on records provided in the table.

    Hi,

    My idea is similar to that found below:

    http://jsfiddle.net/existdissolve/dkJb9/

    Post:
    http://www.sencha.com/forum/showthre...408#post870408

    I would like to gather the information they retrieve, create one row for each.

    Thanks.

    Thanks for the mockup.

    Well, four lines means that you should define four LineSeries.

    You will get an item in the Legend for each LineSeries.

    I agree, but the data are dynamic legend, in the example that I have put four items can return items to be X.

    Thanks.

    I would implement it something like this.

    Example
    <%@ Page Language="C#" %>
    
    <%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
    
    <script runat="server">
        class Item
        {
            public string Date { get; set; }
            public string Description { get; set; }
            public double Percentage { get; set; }
        }
    
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!X.IsAjaxRequest)
            {
                Store store = this.Chart1.GetStore();
                store.DataSource = new object[]
                {
                    new 
                    {
                        Date = "30/06/2012",
                        Descriptions = new string[] { "With maturity 30 days", "With maturity 60 days" },
                        Percentages = new double[] { 16.42, 28.28 }
                       
                    },
                    new 
                    {
                        Date = "31/07/2012",
                        Descriptions = new string[] { "With maturity 30 days", "With maturity 60 days" },
                        Percentages = new double[] { 27.11, 20.95 }
                       
                    }
                };

    Hi,

    This example is correct, I need exactly this, but my data is dynamic, I can't put the fixed LineSeries, I think I'll build it in code-behind.

    It's possible to building this dynamic?

    Thanks.

    Yes, you should create LineSeries and, probably, convert the initial data in code behind. It all is possible.
  10. #10
    Okay, I'll try to implement it in code behind.

    Thanks.
