– cfish Self-adaptable (see p. 34) Cartesian fish-eye view. The effect of the Cartesian fish eye is similar to polar fish-eye view, only that the Cartesian coordinate system is transformed instead of the polar system. In this view horizontal and vertical lines remain horizontal and vertical after transformation, i. e. they are not bent as in the case of polar fish-eye view. – fcfish Cartesian fish-eye view with a fixed radius. Here the fish eye only shows a fixed radius around the focus, meaning the entire graph may no longer be visible. – dcfish Cartesian fish-eye view with a double focus. – pfish Self-adaptable (see p. 34) polar fish-eye view. The plane containing the graph layout is projected onto a sphere. Polar fish-eye view is a 3D look onto this sphere. – fpfish Polar fish-eye view with a fixed radius. Here the fish-eye view only shows a fixed radius around the focus, meaning the entire graph may no longer be visible. – dpfish Polar fish-eye view with a double focus. • width Type: integer Default value: Top-level graph: (width of root screen − 100) pixels Subgraphs: (width of the label for summary nodes) pixels Attribute of: top-level graph, subgraphs Description: The meaning of this attribute depends on its location. – top-level graph This attribute specifies the width of the display window in pixels. – subgraphs Here it specifies the width of the summary node in pixels. See also graph attribute height (p. 73) • x, y Type: integer Default value: Top-level graph: 0 pixels for both Subgraphs: unspecified for both Attribute of: top-level graph, subgraphs Description: The meaning of these attributes differ depending on whether they are specified for the toplevel graph or for subgraphs. – top-level graph Here these attributes specify the position of the graph window in relation to the root 90
screen, i. e. the x and y coordinates of the upper left corner of the graph window are specified in pixels. The origin of the root screen is in the upper left corner. – subgraphs Here they specify the x and y coordinates (in pixels) of the summary node in relation to the upper left corner of the graph window. The positions can also be specified via the loc attribute (p. 78). • xbase, ybase Type: integer Default value: 5 pixels for both attributes Attribute of: top-level graph, subgraphs Description: xbase, ybase specify the horizontal and vertical offset between the graph window and the upper left-hand corner of the graph, i. e. the position of the origin of the coordinate system in relation to the upper left-hand corner of the virtual window. In subgraph specifications they are the offsets from the frame of the box containing the subgraph. • xmax, ymax Type: integer Default value: (width of the root screen − 90) pixels for xmax (height of the root screen − 90) pixels for ymax Attribute of: top-level graph Description: These attributes specify the maximum size of the virtual window used to display the graph (see Figure 30). This is usually larger than the displayed part. The width and height of the displayed part cannot be larger than xmax and ymax. Only the parts of the graph inside the virtual window are drawn. The virtual window can be moved over the potentially infinite coordinate system by special positioning commands (see p. 13). Note: It is advisable to set xmax, ymax so they do not exceed the size of the root screen so as to get good performance. • xraster, yraster Type: integer Default value: 1 pixel Attribute of: top-level graph, subgraphs Description: These attributes specify the horizontal and vertical raster distance for the position of nodes. The center of a node is aligned to this raster. • xlraster Type: integer Default value: 1 pixel Attribute of: top-level graph, subgraphs 91
