Hello I have created a diagram Gantt, but I need to place to the body of the task the executed percentage, is possible this. I am working with the version Net (2003) in aspx Example:
Example:
Task
_________|
_________|
_________|__________________ ____________________
Task1____|__________________|#########B######|
_________|
_________|
_________|
_________| ______________
Task2____||#####A#####|
_________|_____________________________________________ _________02:00__________04:00_______________08:00........Hour

A: percentage of made task , B: percentage of the made task

Dataset:

StartValues|Y | EndValues | NextTasks |LabelMember |MarkValue
------------------------ --- ------------------------ -------- --------------------
2005-11-16 02:58:21.000|0|2005-11-16 03:00:10.000|-1|SC2|10
2005-11-16 02:58:21.000|1| 2005-11-16 03:00:10.000|-1|SC3|50
2005-11-16 04:56:48.000|0| 2005-11-16 05:08:22.000|-1|SC2|30
2005-11-16 04:56:48.000|1| 2005-11-16 05:08:22.000|-1|SC3|10
2005-11-16 05:50:18.000|0| 2005-11-16 06:01:53.000|-1|SC2|6
2005-11-16 05:50:18.000|1| 2005-11-16 06:01:53.000|-1|SC3|8
2005-11-16 06:59:02.000|0| 2005-11-16 07:00:51.000|-1|SC2|9

Dim Chart1 As Steema.TeeChart.Chart = GraficoWeb.Chart
Chart1.Aspect.View3D = False
Dim bubble1 As Steema.TeeChart.Styles.Gantt = New Steema.TeeChart.Styles.Gantt(Chart1)
bubble1.StartValues.DataMember = "StartValues"
bubble1.StartValues.DateTime = True
bubble1.EndValues.DataMember = "EndValues"
bubble1.EndValues.DateTime = True
bubble1.YValues.DataMember = "Y"
bubble1.LabelMember = "LabelMember"
bubble1.NextTasks.DataMember = "NextTasks"

Desire to obtain this, but is not possible to me Task :

Task
________|
________|
________| ______________ __________________
Sec3____||#####50#####| |#######10######| .......
________|
________|
________| .......

Hi mhisi,

To achieve that you could use a fake gantt series overlapping the existing one doing something like this:

Code: Select all

    private void Form1_Load(object sender, EventArgs e)
    {
      gantt1.FillSampleValues(5);
    }

    private void DrawGanttPercentages()
    {
      Steema.TeeChart.Styles.Gantt gantt2 = new Steema.TeeChart.Styles.Gantt(tChart1.Chart);
      gantt2.ShowInLegend = false;

      for (int i = 0; i < gantt1.Count; i++)
      {
        double percent = i;
        gantt2.Add(gantt1.StartValues[i], gantt1.StartValues[i] + percent, gantt1.YValues[i], Color.Blue);
      }
    }

    private void button1_Click(object sender, EventArgs e)
    {
      DrawGanttPercentages();
    }

I do not speak ingles reason why I believe that it was not explained, on the basis of dataset that this in the message is possible to place in mark a customized value I do not calculate of a percentage, if not but well an own value

Hi mhisi,

The approach I posted yesterday can also be applied to series feed by a dataset. Regarding custom marks, you can use GetSeriesMark event to customize the text.
