29.16.4 Color Map Surface

Color-Map-Surface

Data Requirements

• Worksheet: Select at least one Z column (or a range from at least one Z column). If the Z column has associated XY columns, then the XY columns are used; otherwise, the worksheet's default XY values are used.

• If you have XYZZ data, want to plot a 3D surface and set the second Z as colormap, you can specify the mapping column on Fill tab of the Plot Details dialog.

or

• Matrix: A matrix of Z values.

• If you have two matrices and want to color map a surface plot using a second matrix, these two matrices should be in same matrixsheet as matrix objects.

or

• Image: the active page of an Image window

Creating the Graph

Activate the matrixsheet/image window or select required data from worksheet.

From the menu, choose Plot > 3D: 3D Color Map Surface.

or

Click the Color Map Surface button on the 3D and Contour Graphs toolbar.

Template

• glCMAP.OTP (OpenGL)
• Cmap.OTP

(Installed to the Origin program folder).

Notes

The Z values determine a surface of X and Y grid lines and fill color from a color map.
