You have chosen to analyse your conceptual representation using the PrinGrid Map method.
The PrinGrid principal components analysis algorithm treats the It rotates the space to represent the points as much as possible in a space of lower dimensionality.
It plots the You can show or hide a list of the parameters that control what is displayed.
Clicking on There are five sub-sections to the PrinGrid Map Parameters panel: the top row of controls, the "Plot" section, the "Text" section, the "Style" section and the "Use" section.
In the top row:
Clicking on the "Continue" button at the far right returns to the main page.
Clicking on the "PrinGrid Map" button causes the plot to be produced again with the new parameters.
Clicking on the "Image" button on the left displays a menu of options for preserving the current plot: The "Plot" check box when checked causes the PrinGrid Map analysis to be plotted.
The "Title" check box when checked causes the plot to be titled.
The "Numbers" check box when checked causes the The "Variance" check box when checked causes the percentage variance in each lower dimensional component to be shown.
The "Axes" check box when checked causes the axes of the lower-dimensional space to be shown.
The "Labels" check box when checked causes any axes to be labelled with the proportion of variance they represent.
The menu at the right allows the data to be anlyzed to be specified as Distances or Covariances.
The "Power" value specified the Minkowski metric to be used for distances.
On the left of the next two rows are check boxes to specify whether the On the right of these rows are further controls for the plot: -
The "Margins" values specify additional space extending the axes and Voronoi diagram, if any (e.g. "20, 30" specifies 20px horizontally and 30 vertically, a single number specifies both, and a V after the numbers specify they only apply if a Voronoi diagram has been specified).
The "Voronoi" check box when checked causes a Voronoi diagram to be plotted for the The "Dimensions" check box when checked causes the The "Means" check box when checked causes dimensions to be centred on the The next row provides further controls for the plot: -
The "Scale" value specifies the overall scale of the plot.
The "Cutoff" value specifies the minimum proportion of variance for a component to be considered.
The "C/E" value specifies the ratio between the range of The "Spread" check box when checked causes the The three menus in the next two rows specify which components will be plotted.
The "Reverse" check box next to each menu if checked specifies that the component will be plotted reversed.
The "3D" check box when checked causes causes a 3D plot to be generated.
The three numbers following it specifying the degrees of rotation of each axis in the 3D plot..
The "Scree" check box when checked causes a scree plot from a principal components analysis to be shown.
The "Title" check box when checked causes the plot to be titled.
The "Compare" check box when checked adds a plot of the expected random distribution, whichs allows the number of significant components to be estimated by comparison.
The "Scales" text box takes up 4 numbers separated by spaces. The scree plot parameters are common to Map and Synopsis—changing them in one applies them to the other.
The "Text" check box when checked causes the PrinGrid Map analysis to be output in textual form.
The check boxes determine whether percentage variance in each component and the loadings of the The "Style" sub-section top row allows the font and font size used in the plot to be changed,
and the plot to be shown without a background or in black and white.
The next three rows enable the colors used in the plot to be specified
by clicking the color swatches.
The final row enables the identifier used in the plot title to be specified.
An item may be created on the "Options" page named "ID" and used as a customized identifier for the grid,
and/or some combination of the name, note, date and time may be specified.
If nothing is specified the default identifier is the name followed by the note in parentheses.
The style parameters are common to all analyses so that changing them in one applies consistent changes to the others.
The "Use" sub-section specifies whether only selected The "All" button at the top selects all If any of the "Data Types" check boxes on the main page are checked this sub-section also gives the options to use The selection and weight parameters are common to all analyses so that changing them in one applies them to the others.
