Adding A Line or Curve to a Graph In DIAdem

How do I display a line parallel to the X axis at a constant Y value on my DIAdem plot?

Follow the steps below to manually generate a graph from example data, and then add a constant line to the graph:

1. Go to your report tab

2. Add a Simple 2D Axis System to the report by clicking the 2D Graph icon, clicking on the Simple 2D Axis System, then dragging your cursor into the report window.​

3. Open the Data Portal and select the data you would like to plot. for this example we selected Noise_1 from DIAdem's example data. Drag this data into the Simple 2D Axis plot.

4. To add a line or curve, right-click the 2D Axis Plot » Display.

5. Select New Entry
 

 
6. Select Curve Parameters

7. To generate a constant line, select Constant from the left hand menu, and type the desired valueinto the field labeled X-constant. Click OK until you are back at the main graph.
 

 
8. You can now view the constant line on your graph.

Follow the steps below to programmatically generate a graph from example data, and then add a constant line to the graph:
 

1. This section of the code creates the Plot

Call PicLoad("Template") 
Call GraphObjNew("2D-Axis","2DAxis1") 
Call GraphObjOpen("2DAxis1") 
Call GraphObjNew("2D-Curve","New_Curve") 'Creates a new curve 
Call GraphObjOpen("New_Curve") 'Opens the curve object 
D2CChnXName = "EXAMPLE/Time" 
D2CChnYName = "EXAMPLE/Speed" 
Call GraphObjClose("New_Curve") 
Call GraphObjClose("2DAxis1") 
Call PicUpdate 
 

2. This section of the code creates a new constant curve, which is parallel with the X axis

call GraphObjOpen("2DAxis1") 
Call GraphObjNew("2D-curve", "Constant Y") 
Call GraphObjOpen("Constant Y") 
D2CCurveType = "Constant" 
D2CConstXName = "NOVALUE" 
D2CConstYName = "32" 
D2CurveColor = "green" 
Call GraphObjClose("Constant Y") 
Call GraphObjClose("2DAxis1") 
Call PicUpdate 
 

3. This section of the code creates a new constant curve, which is parallel with the Y axis

call GraphObjOpen("2DAxis1") 
Call GraphObjNew("2D-curve", "Constant X") 
Call GraphObjOpen("Constant X") 
D2CCurveType = "Constant" 
D2CConstXName = "30" 
D2CConstYName = "NOVALUE" 
D2CurveColor = "red" 
Call GraphObjClose("Constant X") 
Call GraphObjClose("2DAxis1") 
Call PicUpdate
 
If you run the code above you should see the following plot in the DIAdem report:
