Change Series Orientation

[silken_solitude]

How to I change the series orientation? 

I would like to plot my data on the X axis as opposed to the default y axis.

e.g.

dataChart.Value(1, 0) = 32

plots 32 on the y axis. I would like to plot 32 on the X axis.

dataChart.Value(1, 0) is the Y-Value, dataChart.XValue(1, 0) is the X-Value.

Hey Frank,

Thank for the quick reply!

I tried what you suggested but Im getting an error.  Heres a snippet of my code.

 On Timer tick:

  'Plot on Chart
  'Switch real-time styles once buffer is full
  If nOffset = BufferSize Then
  dataChart.RealTimeSettings.Style = SoftwareFX.ChartFX.RealTimeStyle.NoWaitArrow
  dataChart.Refresh()
  End If

  ''Set Communication Channel styles
  ''These COD values instruct Chart FX about the Realtime settings
  ''the chart, values and legend.
  Dim nCOD As SoftwareFX.ChartFX.COD
  nCOD = SoftwareFX.ChartFX.COD.XValues Or SoftwareFX.ChartFX.COD.RealTime
  nCOD = nCOD Or SoftwareFX.ChartFX.COD.ScrollLegend

  ''Add a point for each sereis to the right of the chart
  ''Using the legend property, set the legend values

  dataChart.OpenData(COD.XValues Or COD.AddPoints, 2, 1)

  dataChart.XValue(1, 0) = dataPoint
  dataChart.Legend(0) = Str(nOffset + 1)
  dataChart.CloseData(nCOD)
  nOffset = nOffset + 1

 

The Error:

System.NullReferenceException was unhandled
