29.17.1 3D Scatter Graph

Mat-3DScatter

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

• A block of worksheet cells (virtual matrix)

or

• Matrix: A matrix of Z values.

Creating the Graph

Activate the matrixsheet or select required data from worksheet

From the menu, for worksheet data, choose Plot > 3D : 3D Scatter; for matrix data, choose Plot > 3D: 3D Scatter.

or

Click the Matrix 3D Scatter button on the 3D and Contour Graphs toolbar.

Notes

• To make this graph you must select columns designated as X, Y and Z.
• To plot the X error and Y error onto the 3D scatter,
  • organize the data columns as X, XErr, Y, YErr and Z, then highlight them all to plot a 3D scatter plot.
  • add X, Y and Z error bars to the graph after it is created by clicking Format: Plot, then clicking on the Error Bar tab of Plot Details and designating error bar datasets.
• If you want to plot a 3D scatter with Z error directly, you need to select one more Z data and then select Plot> 3D : 3D Scatter + Z Error bar. Of course, you can add Z error bars to an existing 3D scatter graph in the Error Bar tab of Plot Details.
