Print error when x.inverted is set to TRUE

User (Legacy)

Recommended Posts

I'm using ChartFX for .NET v6.2 and Visual Studio.NET/Windows Form/VB.NET to 

create a scrollable Gantt chart. See attachment for chart visual. When I

try to print the chart from the toolbar, it generates a run-time error. See

below for code and error message. Note in my code that if I set the

x.Inverted property to False, then no run-time error is generated when I


Please advise on solution.





Sub DrawChart()

Dim InitStart As DateTime = #6/1/2005#

Dim InitStartOA As Double = InitStart.ToOADate

Dim PointCount As Integer = 70

Dim y, x As Axis

Chart1.Scrollable = True

x = Chart1.AxisX

x.PixPerUnit = 20

x.Step = 1

x.Inverted = True 'If set to False, then no run-time error

y = Chart1.AxisY

y.Step = 5

y.Min = InitStartOA

y.Max = InitStartOA + (2 * PointCount) + PointCount

y.LabelsFormat.Format = AxisFormat.Date

y.LabelAngle = 90

Chart1.OpenData(COD.Values, 1, COD.Unknown)

Chart1.OpenData(COD.IniValues, 1, COD.Unknown)

For i As Integer = 0 To PointCount

Chart1.IniValue(0, i) = InitStartOA + i 'start

Chart1.Value(0, i) = InitStartOA + i + (2 * i) 'finish

x.Label(i) = "Task " & i




End Sub
