Mark data source

[Pujol1986]

Hello, i'm making a gantt chart and i have to change the mark text.

I have a lot of options to show different information, but i have to show a specified data that i have in a dataset.

how i can change the datasource of the Marks?

can i change the Marks text like the color of the gantt bars?

exemple:

Gantt1.Colors(0) = Color.Red

thanks.

Hi Pujol1986,

Yes, you have several options here:

1. You can assign it directly to Labels StringList:

Code: Select all

			gantt1.Labels[0] = "first bar";

2. You can add them when populating series using Add method:

Code: Select all

			gantt1.Add(startDate, endDate, y, "first bar", yourColour);

3. You can assign them using a datasource and LabelMember property as shown in the examples here:

Hi Narcís,

i test the code but it change the label of the task and i don't want it.

i need to change only the Mark of the task, for exemple:

I have a Task that have the Label "Máquina 105" and i want to show in the Mark the % of task completion.

If i put the code that you give me the label will change it's value to % of task completion.

how can i change the Mark value without changing the label of the task?

Thanks.

Hi Pujol1986,

To modify the marks without modifying the axis labels, you could use gantt's event GetSeriesMark, for example, to modify the first mark:

Code: Select all

Private Sub Gantt1_GetSeriesMark(ByVal series As Steema.TeeChart.Styles.Series, ByVal e As Steema.TeeChart.Styles.GetSeriesMarkEventArgs) Handles Gantt1.GetSeriesMark
        If e.ValueIndex = 0 Then
            e.MarkText = "my custom label"
        End If
    End Sub

it's done.

thanks.
