Issue Details

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

Solution

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 
     
    1. 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 
     
    1. 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:
