Winform strip line requirements - Branched from F 34133

[U. Korsmit]

Hi Jenith,

The platform is winforms :vb.net.

The version is:  28.1.33

No special or other settings.

The code snippet is the snippet used above: ChartStatLines_6068.zip 

This is unfortunatly not in the correct language.

for the errors, I just deleted the form building line about the orientation.. This parameter does not seem to exists  (anymore).

For the license error, I removed the file with the license key (.licx) from the application. Then it worked.. The greatest question remain (the one that I was trying to solve reading this snippet...). So therefore, the snippet is not so relevant anymore but the only question that remains: 

And, how to do this without double values on the X-axis. I have string values, and the same string is present multiple times... The horizontal line must go from the primary Y-axis over the complete chart width.

the X-axis are string labels: 4,5,6,......52,1,2,3,4. These are weeknumbers, But no real numbers ofcourse!!!.. As you see, these values can not be sorted while they must stay in the order of the underlaying table. There is 2 times (Week) 4. (next week, it will be week 5).

So I can not work with min and max value but must be on coordinates or something. 

The sorting is off, while the graph is build in the order 

EDIT: Maybe I should ask this in another forum post: 

While the width of the chartstripline is not easy to control (I can not give ith a width of 0,01) I get big lines if I display something in smaller values. Therefore I want to go back in displaying the data in a line graph (and solving the above by getting all X-vaules from the similar datatable as the displayed columns). I can easiliy draw a nice controlled target line. However, on the drawn target line, I want to put on the line some text. That is easy with a chartstripline but not easy with a normal line.. How to do this? ChatGPT suggest annotations, but I can not find any annotation properties in syncfusion.

Hi Korsmit,

 

We have prepared a sample in WinForms VB .NET, similar to the one you previously provided. We've modified the double value axis to a category axis using string labels. Please review the attached sample for your reference.

 

Here is a simple code snippet:

 

Private Sub InitializeComponent()

    Dim resources As New System.Resources.ResourceManager(GetType(Form1))

    Me.chartControl1 = New ChartControl()

    Me.SuspendLayout()

 

    Me.chartControl1.Legend.Anchor = AnchorStyles.Top Or AnchorStyles.Right

    Me.chartControl1.Legend.Location = New Point(450, 172)

    Me.chartControl1.Legend.Name = ""

    Me.chartControl1.Legend.Size = New Size(76, 28)

    Me.chartControl1.Legend.TabIndex = 3

    Me.chartControl1.Location = New Point(0, 0)

    Me.chartControl1.Name = "chartControl1"

    Me.chartControl1.PrimaryXAxis.Orientation = Orientation.Horizontal

    Me.chartControl1.PrimaryXAxis.LabelRotate = True

    Me.chartControl1.PrimaryXAxis.LabelRotateAngle = 45

    Me.chartControl1.Text = "Essential Chart"

 

    Me.Name = "Form1"

    Me.Text = "Sample"

    AddHandler Me.Load, AddressOf Me.Form1_Load

    Me.ResumeLayout(False)

End Sub

 

  Protected Sub InitializeChartData()

      Dim random As New Random()

      Dim weekLabels As String() = {"4", "5", "6", "7", "8", "9", "10", "11", "12",

                                    "13", "14", "15", "16", "17", "18", "19", "20",

                                    "21", "22", "23", "24", "25", "26", "27", "28",

                                    "29", "30", "31", "32", "33", "34", "35", "36",

                                    "37", "38", "39", "40", "41", "42", "43", "44",

                                    "45", "46", "47", "48", "49", "50", "51", "52",

                                    "1", "2", "3", "4"}

 

      For i As Integer = 0 To 1

          Dim series As New ChartSeries("Series " & i, ChartSeriesType.Column)

          For j As Integer = 0 To weekLabels.Length - 1

              series.Points.Add(weekLabels(j), New Double() {random.Next(500)})

          Next

          series.Text = series.Name

          series.Style.DisplayShadow = False

          Me.chartControl1.Series.Add(series)

      Next

 

      Me.chartControl1.PrimaryXAxis.DrawGrid = False

      Me.chartControl1.PrimaryYAxis.DrawGrid = False

  End Sub

Query: I can not work with min and max value but must be on coordinates or something. 

Thank you for your understanding and continued support.
