Chart doesn't show Pie view

[André_van_Haren]

I would like to see a Pie view in my Chart, but the chart only shows the Legends at the top of the page, the space below it is empty. When I switch to let it show a Bar view, everything shows correctly. Why can’t I see a Pie view?
The Chart object property in the Inspector is set to Pie. This is the code for creating the Chart:

// Set the title of the chart
StepWords.Title = winmain.ListBoxStories.CellValueAt(winmain.ListBoxStories.SelectedRowIndex,0)
me.TitleFontName = "Times New Roman"
me.TitleFontSize = 24
me.TitleColor = &c63930000
me.LegendColor = &c63930000
me.LegendFontSize = 18
me.LegendFontName = "Times New Roman"

// Define the 12 steps of the Hero's Journey and add labels for each story step with percentage 
Dim heroJourneySteps() As String = Array("Home", "Challenge", "Mentor", "Edge", "No Return", "Antag. Help.", "Antag. Test", "Despair", "Chain Break", "Fight Ready", "Confrontation", "Resolution")

// Add labels for each story step
For nn As Integer = 0 To heroJourneySteps.Ubound
  StepWords.AddLabel(heroJourneySteps(nn))
Next

/// Set the mode of the chart to pie
StepWords.mode = DesktopChart.Modes.Pie

// Create a new dataset with the word count for each story step and add it to your chart:
Var Steps As New ChartLinearDataset("Word Count", Color.Red, True, storyStepWordCount)

// Add the dataset to the chart
StepWords.AddDataset (Steps)

You need to use ChartCircularDataset and not ChartLinearDataset

Edit: note that ChartCircularDataset uses different parameters than ChartLinearDataset

Example using your code as the base:

// Set the title of the chart
Me.Title = "Test for André"
Me.TitleFontName = "Times New Roman"
Me.TitleFontSize = 24
Me.TitleColor = &c63930000
Me.LegendColor = &c63930000
Me.LegendFontSize = 18
Me.LegendFontName = "Times New Roman"

// Define the 12 steps of the Hero's Journey and add labels for each story step with percentage 
Dim heroJourneySteps() As String = Array("Home", "Challenge", "Mentor", "Edge", "No Return", "Antag. Help.", "Antag. Test", "Despair", "Chain Break", "Fight Ready", "Confrontation", "Resolution")

// Add labels for each story step
For nn As Integer = 0 To heroJourneySteps.Ubound
  Me.AddLabel(heroJourneySteps(nn))
Next

/// Set the mode of the chart to pie
// StepWords.mode = DesktopChart.Modes.Pie

Dim mypoints() As Double = Array(3.0,5.0,8.,10.,2.,1.,3.,7.,5.,9.,4.,3.)

Dim mycolors() As Color = Array(Color.Blue,Color.Red,Color.Yellow,Color.Brown, _
Color.Blue,Color.Red,Color.Yellow,Color.Brown, _
Color.Blue,Color.Red,Color.Yellow,Color.Brown)

Var Steps As New ChartCircularDataset("Word Count", mypoints, mycolors)

// Add the dataset to the chart
Me.AddDataset (Steps)
