Dear Sir,
I want to bind data to a chart gantt in order to have :
- Start Date
- End Date
- Y value
- Color
- Label

I tried this solution without success :

Code: Select all

 public class GanttData
    {
        public DateTime Start { get; set; }
        public DateTime End { get; set; }
        public int Y { get; set; }
        public string Label { get; set; }
        public Color Color { get; set; }
    }

          public MainWindow()
        {
            InitializeComponent();

            List<GanttData> lstData = new List<GanttData>();

            GanttData data1;
            
            data1 = new GanttData();
            data1.Color = Colors.Red;
            data1.Start = DateTime.Today;
            data1.End = data1.Start.AddDays(3);
            data1.Label = "Un";
            data1.Y = 1;
            lstData.Add(data1);

            data1 = new GanttData();
            data1.Color = Colors.Green;
            data1.Start = DateTime.Today.AddDays(1);
            data1.End = data1.Start.AddDays(1);
            data1.Label = "Deux";
            data1.Y = 2;
            lstData.Add(data1);

            tChart.Aspect.View3D = false;
            tChart.Header.Text = "Gantt MultipleNextTasks";
            tChart.Legend.Visible = false;

            Gantt gantt = new Gantt(tChart.Chart);
            gantt.ConnectingPen.Visible = false;
            gantt.LabelMember = "Label";

            gantt.Add(lstData);
          }

What is wrong ?
Could you please help me ?

Thank you

Regards,

Philippe

Of course. Your class should look like this:

Code: Select all

  public class GanttData
  {
    public double Start { get; set; }
    public double End { get; set; }
    public int Y { get; set; }
    public string Label { get; set; }
    public Color Color { get; set; }
  }

which you can consume like this:

Code: Select all

    private void InitializeChart()
    {
      List<GanttData> lstData = new List<GanttData>();

      GanttData data1;

      data1 = new GanttData();
      data1.Color = Color.Red;
      data1.Start = DateTime.Today.ToOADate();
      data1.End = DateTime.FromOADate(data1.Start).AddDays(3).ToOADate();
      data1.Label = "Un";
      data1.Y = 1;
      lstData.Add(data1);

      data1 = new GanttData();
      data1.Color = Color.Green;
      data1.Start = DateTime.Today.AddDays(1).ToOADate();
      data1.End = DateTime.FromOADate(data1.Start).AddDays(1).ToOADate();
      data1.Label = "Deux";
      data1.Y = 2;
      lstData.Add(data1);

      tChart1.Aspect.View3D = false;
      tChart1.Header.Text = "Gantt MultipleNextTasks";
      tChart1.Legend.Visible = false;

      Gantt gantt = new Gantt(tChart1.Chart);
      gantt.ConnectingPen.Visible = false;
      gantt.LabelMember = "Label";
      gantt.ColorMember = "Color";
      gantt.StartValues.DataMember = "Start";
      gantt.EndValues.DataMember = "End";
      gantt.YValues.DataMember = "Y";

      gantt.DataSource = lstData;
    }

Dear Christopher,

Thank you very much for your reply.
I applied your code but the result is wrong about the date displayed.

Is it possible also to insert mark inside, different of label ?

Thank you

Hello Phillippe,

Many apologies for not seeing that issue earlier - I have added it to our ticket tracker with id=1621 and have already resolved it, meaning that a resolution to this problem will be found in the next maintenance release, due out in the middle of this month. I'm afraid to say that there is no workaround available to this issue.

Dear Christopher,

No problem, until the release I resolved in this way :

Code: Select all

           foreach (GanttData data in lstData)
            {
                gantt.Add(data.Start, data.End, data.Y, data.Label, data.Color);
            }

Is it possible to have the Marks with different value ?
How to do it ?

Hello Phillippe,

You always have the option to do something like this:

Code: Select all

    private void InitializeChart()
    {
      List<GanttData> lstData = new List<GanttData>();

      GanttData data1;
      DateTime date = DateTime.Today;

      for (int i = 0; i < 3; i++)
      {
        data1 = new GanttData();
        data1.Color = Color.Red;
        data1.Start = date;
        date = date.AddDays(3);
        data1.End = date;
        data1.Label = "Un " + ((i > 0) ? i.ToString() : "");
        data1.Y = 1;
        lstData.Add(data1);
      }

      date = DateTime.Today.AddDays(1);

      for (int i = 0; i < 3; i++)
      {
        data1 = new GanttData();
        data1.Color = Color.Green;
        data1.Start = date;
        date = date.AddDays(3);
        data1.End = date;
        data1.Label = "Deux " + ((i > 0) ? i.ToString() : "");
        data1.Y = 2;
        lstData.Add(data1);
      }

      tChart1.Aspect.View3D = false;
      tChart1.Header.Text = "Gantt MultipleNextTasks";
      tChart1.Legend.Visible = false;

      Gantt gantt = new Gantt(tChart1.Chart);
      gantt.ConnectingPen.Visible = false;
      gantt.Marks.Visible = true;

      foreach (GanttData data in lstData)
      {
        gantt.Add(data.Start, data.End, data.Y, data.Label, data.Color);
      }
    }

which will give you the following chart:

Christopher,

Yes, but the first 'Mark' value is the same of the Label !
No other possibilities to avoid this ?

Thank you

Hello Phillippe,

Yes, you can use Custom Labels, e.g.

Code: Select all

    private void InitializeChart()
    {
      List<GanttData> lstData = new List<GanttData>();

      GanttData data1;
      DateTime date = DateTime.Today;

      for (int i = 0; i < 3; i++)
      {
        data1 = new GanttData();
        data1.Color = Color.Red;
        data1.Start = date;
        date = date.AddDays(3);
        data1.End = date;
        data1.Label = "Un " + ((i > 0) ? i.ToString() : "");
        data1.Y = 1;
        lstData.Add(data1);
      }

      date = DateTime.Today.AddDays(1);

      for (int i = 0; i < 3; i++)
      {
        data1 = new GanttData();
        data1.Color = Color.Green;
        data1.Start = date;
        date = date.AddDays(3);
        data1.End = date;
        data1.Label = "Deux " + ((i > 0) ? i.ToString() : "");
        data1.Y = 2;
        lstData.Add(data1);
      }

      tChart1.Aspect.View3D = false;
      tChart1.Header.Text = "Gantt MultipleNextTasks";
      tChart1.Legend.Visible = false;

      Gantt gantt = new Gantt(tChart1.Chart);
      gantt.ConnectingPen.Visible = false;
      gantt.Marks.Visible = true;

      foreach (GanttData data in lstData)
      {
        gantt.Add(data.Start, data.End, data.Y, data.Label, data.Color);
      }

      tChart1.Axes.Left.Labels.Items.Add(1, "Uno");
      tChart1.Axes.Left.Labels.Items.Add(2, "Dos");
    }

which gives me:
