3D Contour Plots - Quick Tab

Graphical Analytic Techniques

Select the Quick tab of the 3D Contour Plots Startup Panel to specify the variables, fit, and contour style of the 3D contour plot as well as whether to include the raw data points in the plot.

Variables

Click the Variables button to display the standard variable selection dialog box, in which you can select the x-, y-, and z-axis variables for the graph. The selection made will be displayed below the Variables button.

Fit

You can fit one of several equations to the data or use one of the data smoothing procedures in the 3D contour plot by selecting one of the predefined functions on this tab.

Linear	Neg Expon Weighted LS
Quadratic	Spline
Distance Weighted LS	Wafer

Contour Style

You can display the contour as a series of Lines or Areas. See also, Calculating Contour Levels and Distance.

Show Raw Data Points

Select this check box if you want the raw data points to be overlaid on the graph contour.

Overlaid Contour Plot

The options in this group box are available when there are multiple z variables selected.

Overlaid Contour Plot

Select this check box to create an overlaid contour plot, where the variables are overlaid in one graph and identified by patterns and colors. The Z variables will be displayed in a text field where you can edit the contour range for each variable. Note that invalid range values will be ignored.

Define contour range. Select one of the options from the Define contour range drop down list to define the low and high contours.

Data mean +/- std dev. Use this option to define the contour range from to .

Data mean +/- std err. Use this option to define the contour range from to .

Data min-max. Use this option to define the contour range from xmin to xmax.

Fit range 25%-75%. Use this option to define the contour range from the 25th percentile to the 75th percentile of the data.

Custom min-max. Use this option to define your own custom contour range. Enter the custom values into the Min and Max fields.

Min/Max

If you have specified to define your own custom values, specify the low value in the Min field and the high value in the Max field.
