[Resolved] : Report Builder Line chart Issue

Hello,

I have an Issue with Report Builder 2012, in a report with Line Chart.

I have this sample of data :

The Line chart used from the SQL Server Report Builder show me a chart like this :

As you can see, the blue line from Feb 2018 to Feb 2019 is not linked, I guess it is due to the fact that it cross the Yellow one.

I searched in this Forum and I tried a solution who looks like :

Private colorPalette As String() = {"#418CF0", "#FCB441", "#E0400A", "#05642E", "#1A3B69", "#BFBFBF", "#E0400A", "#FCB441", "DarkBlue", "Tomato", "Orange", "CornflowerBlue", "Gold", "Red", "Green", "LightBlue", "Lime", "Maroon", "LightSteelBlue", "Tan", "Silver"}
Private count As Integer = 0
Private mapping As New System.Collections.Hashtable()

    Public Function GetColor(ByVal groupingValue As String) As String

        If mapping.ContainsKey(groupingValue) Then
                Return mapping(groupingValue)
        End If

        Dim c As String = colorPalette(count Mod colorPalette.Length)
            count = count + 1
            mapping.Add(groupingValue, c)
            Return c
    End Function

Then I user the EmptyPoint Series property to call this Function. All details about this solution are given by this link :

The problem now after using this, my chart looks like this :

All the Yellow Part from June 2018 to the end of the Chart does not have to be drown because my Data for this Yellow line end at June 2018.

Does Any one can help please ? I Forgot Something ?

Thank you
