27.14.4 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.

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 matrix sheet as matrix objects.

If you have XYZZ data, want to plot a 3D surface and set the second Z as colormap, you need first convert these two Z data to two matrix objects in same matrix sheet.

Creating the Graph

Activate the matrix sheet 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.
