Object: TransformDataContextConstantXY
The TransformDataContextConstantXY object provides the input and output constants for the curve transformation of a curve with the Constant or Coordinate display type as an object in a 2D axis system in DIAdem REPORT. The user command receives the TransformDataContextConstantXY object as a parameter. Use the curve transformation user command only to manipulate the values of temporary copies of the input channels. REPORT objects such as the worksheet, the axis system, and the curves can only be accessed in read-only mode.
![]() | Note To test the example script, you must first save the second script and register it as a user command in the dialog box that opens when you select Settings»Extensions»User Commands. |
The following example generates an axis system with two constants and assigns the MyOnCurveTransformation user command to the second constant:
Dim oMy2DAxisSystem, oMyCurveLine, oMyCurveConstOrg, oMyCurveConstTrans, oMyPos, oMyLineShape, oMyXScaling, oMyYScaling Call Report.NewLayout() Set oMy2DAxisSystem = Report.ActiveSheet.Objects.Add(eReportObject2DAxisSystem, "My2DAxisSystem") Set oMyPos = oMy2DAxisSystem.Position.ByCoordinate oMyPos.X1 = 20 oMyPos.X2 = 80 oMyPos.Y1 = 20 oMyPos.Y2 = 80 Set oMyXScaling = oMy2DAxisSystem.XAxis.Scaling oMyXScaling.AutoScalingType = eAxisAutoScalingBeginEndManual oMyXScaling.Begin = 0 oMyXScaling.End = 70 Set oMyYScaling = oMy2DAxisSystem.YAxis.Scaling oMyYScaling.AutoScalingType = eAxisAutoScalingBeginEndManual oMyYScaling.Begin = 0 oMyYScaling.End = 70 Set oMyCurveConstOrg = oMy2DAxisSystem.Curves2D.Add(e2DShapeConstant, "MyOrgConstant") oMyCurveConstOrg.Shape.XConstant.Reference = 10 oMyCurveConstOrg.Shape.YConstant.Reference = 20 Set oMyCurveConstTrans = oMy2DAxisSystem.Curves2D.Add(e2DShapeConstant, "MyTransConstant") oMyCurveConstTrans.Shape.XConstant.Reference = 10 oMyCurveConstTrans.Shape.YConstant.Reference = 20 oMy2DAxisSystem.Settings.UseCurveTransformation = TRUE oMyCurveConstTrans.OnCurveTransformation = "MyOnCurveTransformation" Call Report.Refresh()
The user command adds the value 20 to the values of the constants:
Sub MyOnCurveTransformation(Context) Dim oMyDataContext Set oMyDataContext = Context.DataContext Select Case Context.DataType Case e2DCurveTransformDataTypeXY Call ChnCopy (oMyDataContext.XChannelNumberIn ,oMyDataContext.XChannelNumberOut) 'Copy the input channel into the output channel Call ChnSmooth(oMyDataContext.YChannelNumberIn, oMyDataContext.YChannelNumberOut, 100, "symmetric") 'Smooth the input channel and save the result as output channel Case e2DCurveTransformDataTypeXYY1 Call ChnCopy (oMyDataContext.XChannelNumberIn ,oMyDataContext.XChannelNumberOut) 'Copy the input channel into the output channel Call ChnSmooth(oMyDataContext.YChannelNumberIn, oMyDataContext.YChannelNumberOut, 2, "symmetric") 'Smooth the input channel and save the result as output channel Call ChnSmooth(oMyDataContext.Y1ChannelNumberIn, oMyDataContext.Y1ChannelNumberOut, 2, "symmetric") 'Smooth the input channel and save the result as output channel Case e2DCurveTransformDataTypeCXCY oMyDataContext.ConstXOut = oMyDataContext.ConstXIn + 20 oMyDataContext.ConstYOut = oMyDataContext.ConstYIn + 20 End Select End Sub
