Minimum Origin Version Required: Origin 2015 SR0

What you will learn

This tutorial will teach you how to:

  • Create the 3D Surface with side walls
  • Add a 3D scatter to the 3D Surface and include labels
  • Change the label position in 3D graphs
  • Add a line to connect the symbol and the label

Steps

Create the 3D Surface with side walls:

This tutorial is associated with <Origin EXE Folder>\Samples\Tutorial Data.opj.
Also, you can refer to this graph in Origin Central. (Select Help: Origin Central menu or press F11 key , and then open Graph Sample: 3D Surface)

  1. Open Tutorial Data.opj and browse to the 3D Surface with Point Label folder in Project Explorer (PE).
  2. Activate MBook4, and highlight everything. Select Plot:3D Surface: Color Map Surface from the main menu. A 3D Colormap graph will be generated as shown below:

  4. Select Format: Plot Properties in the menu to open the Plot Details dialog. (Or double click anywhere on the graph). If the left panel is not expanded use the Plot Details Expansion.png button on the bottom left of the dialog to expand it and select the first option under Layer1. In order to create and customize side walls, in the Side Walls tab, check the Enable box. Change the color of X and Y side walls to Gray and LT Gray.

Add the 3D scatter in the 3D Surface with labels:

  1. In order to add symbols in the desired position on the 3D graph, select Graph: Layer Contents from the main menu to open the Layer Contents dialog (Or double click on the layer icon 1 on the top left of the graph). In the dialog that appears, select Worksheet in Folder from the drop-down on the top left.
  2. Click on the Plot Type button shown below to specify 3D Scatter/ Trajectory/ Vector as the plot type:

  4. To add labels to the two symbols, double click on either one to open the Plot Details dialog. Make sure the left panel of the Plot Details dialog box is expanded and displaying Original under the Position1 plot-level. In the Label tab check the Enable box. In the Label From drop-down list, select col("Label") as the label source. Specify the Offset for the label as shown in the image below:

  6. To add leader lines to connect the symbols and the labels, when the graph window is active select Window:Script Window from the main menu and run the following script:
    layer.plot=2;
    set %C -ql 5;
    layer.plot=3;
    set %C -ql 5;

    Highlight the script and press Enter. Leader lines connecting the labels and the symbols will appear and the graph should resemble the image shown below:
