3D Contour Plots
- Quick Tab 3D Contour Plots
- Quick TabSelect the Quick tab of the 3D Contour Plots dialog 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, in which you can select the x-, y-, and z-axis variables for the graph. The selection that you make will then be displayed in the area of the dialog 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.
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. 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. If you have specified to define your own custom values, then specify the custom low value in the Min field.
