6.12.13 Multiple Surfaces in Same Layer

Summary

The four stacked surfaces shown below were created from the same matrix. The first layer from the top is a wire frame, the second layer is a flattened contour line plot, the third layer is a color filled surface with lighting effect, and the bottom layer is a flattened color filled contour plot.

Minimum Origin Version Required: Origin 2015 SR0

What You Will Learn

This tutorial will show you how to:

  • Add multiple surface plots to a single graph layer
  • Explore ways in which you can customize surface plots

Steps

Create a Graph with Multiple Surfaces

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 Multiple Surfaces in Same Layer folder in Project Explorer (PE).
  2. Select the MBook8 worksheet and highlight all that data. From the Main Menu select Plot: 3D Surface: Colormap Surface. The graph window should appear as shown below:

  3. With the new graph window active choose Graph: Layer Contents.... In the Layer Contents - Layer 1 dialog box, select the MBook8 matrix in the left panel and click the Add plot button (the right-pointing arrow in the center of the dialog) three times. Click OK. This will add the same MBook8 data to the graph layer four times. Note that at this point there only a single plot, the following steps will change that.

  4. Double-click on the plot to open the Plot Details - Plot Properties dialog box. Select the first plot in the left-hand panel and in the Surface tab check the Flat box, check Shift in Z by percent... and enter 0 in the accompanying text box. Select the second plot, leave Flat unchecked, check Shift in Z... and enter 23. Select the third plot, check Flat, check Shift in Z... enter 65. Select the fourth plot, leave Flat unchecked, check Shift in Z... and enter 82. Click OK.

  5. Double-click on the Z axis, and in the Axes Dialog box, go to the Scale tab, make sure Z axis icon is selected and set From to 0 , and To to 900.
