Plot Area Properties
Position the mouse pointer in the Plot Area and right-click to display a context menu. On the context menu, click Plot Area Properties. IML Studio displays a dialog box containing the
following tabs:
- Surface
This tab provides the following controls:
- Axis Locations
- This option button specifies the location of axes. There are four options:
- At midpoint
- The origin of each axis is placed at the midpoint of the range of the variable for that axis.
- At minima
- The origin of each axis is placed at the minimum value of the variable for that axis.
- 3 sections
- Each axis is placed on an edge of the bounding cube surrounding the data so that the axis interferes as little as possible with viewing the data.
- Off
- No axes are displayed.
- Surface Drawing Modes
- This option button specifies the attributes of the surface added to the rotating plot.
- Transparent mesh
- The surface is drawn as a wire mesh, but hidden-line removal is not performed.
- Opaque mesh
- The surface is drawn as a wire mesh and hidden-line removal is performed.
- Block color mesh
- The surface is drawn as a patch of rectangles in which each rectangle is a single color.
- Smooth color mesh
- The surface is drawn as a patch of triangles in which each triangle is a single color.
- Stacked contours
- The surface is not drawn, but contour levels are drawn.
- Stacked contours mesh
- The surface is drawn as for Opaque mesh and also contour levels are added as for Stacked contours.
- Off
- No surface is displayed.
- Contour Projections
- These options specify whether contours of the data are shown in the (X,Y) plane.
- Show contour lines
- This check box specifies whether contours for the surface are shown projected onto the (X,Y) plane.
- Show contour areas
- This check box specifies that region between projected contours are filled with color.
- Show contour values
- This check box specifies whether projected contour lines are labeled by the value of the Z axis variable.
- Contours
This tab is exactly the same as that for the contour plot. See Contour Plot: Plot Area Properties.
- Grid
The plot uses a computational grid to fit a surface to the data. The algorithm that computes the surface uses a grid superimposed on the (X,Y) plane. This grid consists of (NumXLines
- 1) subdivisions along the X axis and (NumYLines - 1) subdivisions along the Y axis. Generally, more subdivisions results in a smoother surface whereas fewer subdivisions results
in a rougher surface.
This tab provides the following controls:
- Show grid
- This check box specifies whether to display a grid on the displayed surface.
- Colors
- These drop-down color selectors specify the color of the grid when seen from the front (positive Z direction) or back (negative Z direction).
- If the surface drawing mode is such that hidden lines are displayed, the Front color is used for the entire computational grid.
- Resolution
- These options specify the resolution of the computational grid used to fit a surface to the data. X lines specifies the resolution of the computational grid in the X direction;
Y lines specifies the resolution of the computational grid in the Y direction.
